What is the function of cactus?
Cactus has many uses and great contribution to medicine. The whole plant is used as medicine (except thorns). It can be harvested all year round. Fresh or sliced and dried. Has the effects of clearing away heat and toxic materials, relaxing muscles and tendons, activating collaterals, removing blood stasis, relieving swelling, relieving intestinal toxicity, cooling blood, stopping bleeding, invigorating stomach, relieving pain, and relieving cough. For gastric and duodenal ulcers, hemorrhoids, acute dysentery and cough; Externally used for treating parotitis, mastitis, carbuncle and furuncle, external hemorrhoid, snake bite, burn and scald.
2. Vegetable consumption:
Cactus, as a vegetable, is also a kind of use. Cactus has always been a traditional food in the United States, and it is an indispensable characteristic vegetable and fruit in people's daily life. People wash and chop the cactus and cook it in soup, or bake it on the stove, or make it into pie stuffing, or pickle fresh cactus directly, and some use cactus to make wine (tequila). Edible cactus is one of the vegetables with the highest vitamin B2 and soluble fiber, and cactus is high in potassium, low in sodium and low in sugar, and its sugar content is lower than lettuce and cucumber.
3, indoor greening:
The simplest use of cactus is indoor greening, and it is called "oxygen bar" at night. Cactus mostly breathe at night when it is cool and humid. When breathing, inhale carbon dioxide and release oxygen. Don't underestimate that cactus is a master of dust adsorption, others are still masters of dust adsorption! Placing a cactus in the antimony star room, especially hydroponic cactus (because hydroponic cactus is cleaner and more environmentally friendly), can purify the environment.
4. Other uses:
Cactus is also used in many aspects, such as beauty and water storage. Cut the cactus with a knife to get juice and apply it to your face. /kloc-Wash with clean water after 0/5 minutes, which has the effect of whitening and hydrating. There is a layer of wax on the surface of cactus, and the leaves have evolved into needles, which reduces the external area and thus reduces water transpiration; Cactus contains toxic alkali, which can act on the central nervous system after eating, causing various hallucinations. It was an important plant in Peru from the first century to the seventh century.
Cultivation of cactus:
1, water and spray water
Terrestrial cactus has obvious growth period and dormancy period, so it needs watering in the growth period, and less or even no watering in the dormancy period. Epiphytic type, the temperature is kept above 65438 02℃ in winter, and it can be watered and sprayed all year round; When the temperature is kept below 12℃ in winter, watering can be reduced and water spraying can be stopped as appropriate. When watering, master the principle of "dry thoroughly, don't do it without watering"; The water temperature should be as close to the soil temperature as possible. Water should be done early (before sunrise) and late (after sunset) in summer and10am ~1/am in winter. And pour the water directly on the pot soil, otherwise it will affect the beauty of the thorn. In addition, water should be sprinkled on the ground in summer to increase air humidity.
Step 2 apply fertilizer
Fertilization should follow the following principles: timely, appropriate and targeted. Fertilization should be carried out in spring and autumn, every 20 days 1 time, and in the early morning or evening on sunny days. If the basin soil is dry, sprinkle some water on the basin soil and then fertilize it, with the concentration of 0.05% ~ 0.2%. Pour 1 time the next morning, and the effect will be better. Land fertilization needs fertilizers rich in potassium, phosphorus and less nitrogen, while epiphytic fertilization needs more nitrogen.
3. Lighting equipment
Lusheng prefers sunshine, especially in winter. Generally, tall, cylindrical and flat cactus is resistant to strong light and can be placed outdoors in summer without shading; Smaller spherical species prefer semi-cloudy environments in summer. In summer and high temperature season, from June to August, a round plastic film is covered around the growth point at the top of Jinhu, so that all parts of the sphere grow evenly. Epiphytic cactus needs semi-cloudy environment all year round.
4. Temperature
The optimum temperature for cactus growth is between 20 ~ 35℃. Terrestrial land does not require high temperature in winter dormancy period, and the temperature can be maintained at 4 ~ 7℃ while keeping the basin soil dry. Epiphytic winter requires higher temperature, so it is appropriate to maintain 10 ~ 13℃ or higher. When the temperature reaches 30 ~ 35℃ in summer, the growth rate of most cacti will slow down, and sometimes some kinds of stems will turn yellow or be burned. At this time, it is necessary to shade the sun and sprinkle more water on the ground to reduce the temperature.
5. Air
Most cactus flowers are native to desert open areas, with good ventilation and fresh air. Therefore, in the hot weather in midsummer, it is necessary to do a good job of ventilation and cooling in breeding places. The cultivation greenhouse should be in an air circulation environment, and more windows, skylights and other vents should be set up to facilitate ventilation in hot summer weather. When necessary, equipment such as exhaust fan, hair dryer or electric fan can be installed to enhance the air circulation effect of the environment and promote the safe summer of cactus flowers.
6, pests and diseases
There are bacteria and fungi that harm cactus flowers, but the problem is not very serious. As long as the cultivation conditions are improved, the management measures are appropriate, and the prevention and control of pests and diseases are two-pronged, it is easy to achieve good results. Common diseases and insect pests mainly include:
(1) Rot disease. Its pathogens are bacteria and fungi. The occurrence of this disease is often related to improper watering, poor drainage of basin soil and excessive continuous humidity. Immediately after finding the diseased plant, cut off the diseased plant tissue with a sharp knife, smear the incision with charcoal powder or sulfur powder, control watering or changing pots at the same time, and carry out cutting or grafting respectively. It is best to spray 800 ~ 1000 times of 40% copper oxychloride suspension on planting sites and plants regularly for prevention and control, but mainly to improve ventilation conditions and avoid excessive continuous humidity.
(2) Insects and other animals are harmful. There are mainly scale insects, red spiders and clams. 50% omethoate emulsion 1000 times can be sprayed to control scale insects; The control of red spider can be sprayed with 600 times of 20% dicofol wettable powder or 1000 times of 40% dicofol emulsifiable concentrate; To control rats and tide insects, 2000 times of Robam solution can be sprayed around flower stands and flowerpots; To control snails and clams, lime powder can be sprayed around flowerpots, and 8% mirex granules can also be applied; To control cockroaches and ants, drugs for killing cockroaches and ants or sugar water can be added and mixed with trichlorfon drugs for poisoning.
I don't like growing flowers, and neither do my parents, but in order to green the environment, they bought some pots of flowers from the market and put them on the balcony.
There is also a cactus that is not very eye-catching. Why is it called "cactus"? I don't know, maybe it's called "cactus" because its shape is different from human limbs.
"Every morning, I will water those flowers casually, because if I water them too much, they will die easily.
I have also heard that cactus doesn't like drinking water very much, so it is watered every three or four days.
My cactus is dark green and full of thorns, probably because it is not disturbed by the outside world, so there are many thorns on it.
A cactus, a bit like the shape of a cucumber, is connected together, and some hold together like brothers and never part.
Spring is coming, the grass is sprouting, the flowers are in full bloom, the rain is raining, and the fragrance is fragrant, which constitutes a beautiful and perfect spring scene.
But who can notice cactus? It does not covet fame and fortune, and never gives in to difficulties.
Sometimes I also find that there are countless cracks in the soil of cactus, and the soil is rough and dry, but it doesn't mind at all and still stands on a colorless ceramic basin made of soil.
What is this for? In order to contribute to the world, add green to the world, absorb carbon dioxide, release fresh air and make the environment fresher.
Although this flower is beautiful, it is too fragile and easily broken.
Gradually, I fell in love with cactus unconsciously, because its noble quality has always attracted me, and I want to learn from it.
Autumn has come and gone. The cold wind came, the grass withered and the leaves turned yellow.
But the cactus is unwavering, still so green and strong.
It is not afraid of difficulties, dare to fight against them, and fight in the cold wind outside day and night. In the end, it overcame the cold wind with tenacious and resolute spirit.
Its indomitable spirit deeply shocked me. Whenever I encounter difficulties, I always rely on others to help me, and I have never tried to solve the problems in my life by myself.
The spirit of cactus inspires me to move forward.
Although cactus is common, its noble quality is worth learning.
I love cactus! Because cactus guides me on the road of life, not afraid of difficulties and working hard!
At the beginning of the composition of plants, I found out why cactus grows 400 words. Today, I am watering my lovely cactus.
Suddenly, my hand was pricked by something.
When I looked intently, it turned out to be a lovely little cactus.
So I thought: Why do cactus grow thin and sharp thorns instead of tender leaves? On second thought, I decided to check the computer.
It turns out that there are many plants that have been short of water for a long time in the desert.
But in order to survive, cactus evolved its own fleshy tissue with sharp thorns.
This will reduce the loss of water vapor and prevent some animals from eating themselves, thus gaining water in the body.
Cactus can also help travelers in the desert. When travelers are thirsty, they can make a small hole in the cactus, and cool and delicious water will flow out of the hole.
If the thorns of the cactus are broken a lot in the desert, then the cactus will not live long.
I'm thinking: if we plant more trees in the desert, the desert will become an oasis, so if the cactus is affected by the climate, will it degenerate? I think this can only be changed by us.
Have I discovered the revelation of cactus about the secret composition of nature? After reading the book Animal World, I learned about the life characteristics and special abilities of woodpeckers and anteaters. From them, I suddenly thought of a problem and got an inspiration: in rural orchards, we often find pests crawling into tree trunks and mature fruits. In order to protect the fruit forest, farmers have to spray a lot of pesticides. What is the result? Not only is the cost high, but people eat it, and the pesticides that exceed the standard are scary. If pests are not killed in time, people have to cut down those "incurable" fruit trees.
In modern rural areas, it is impossible for so many woodpeckers to help fruit trees see a doctor.
Nature has given people a lot of inspiration. Planes were invented according to dragonflies, and streamlined boats were invented after whales at the bottom of the sea. So I'm thinking: why don't we make a portable pest control machine by imitating the mouth of woodpecker and the tongue of anteater? In this pest control machine, we can install a computer chip, so that it can accurately detect diseased trees. Then, we can press a red button on the handle, and a pointed hooked steel pipe similar to a woodpecker's mouth will pop out from it. It can accurately make a tiny hole in a tree with pests, and then hook it out with a hooked steel pipe mouth.
What about termites? Don't panic, we can put the steel pipe mouth in first, then press the green button, and an anteater-like tongue will pop out of it. As soon as the sticky long tongue "drills" into the hole, termites are easily and completely eliminated.
How beautiful nature is! I love nature!
On the composition of cactus, there is an inconspicuous cactus on my balcony.
Although cactus has no graceful "figure", refreshing fragrance and gorgeous "clothes", it is full of treasures.
So I like it very much.
The cactus's body is like a palm, and it is covered with needles. These needles are all weapons it uses to defend itself and fight back.
Mom was stabbed several times by it.
Once, I asked my mother strangely, "Why doesn't cactus have leaves?" Mother replied: "The leaves of cactus gradually evolved into thorns in order not to be in the desert."
"Cactus germinate all year round. When I first discovered the cactus sprouting, I thought it was going to blossom.
A cactus grows a flower and a bone, and my mother says it will sprout.
It begins with the degeneration of small spines.
After a few days, the bud came out.
The new shoots are light green and very soft.
The little body seems to fall off the main pole at any time.
A few days later, small thorns began to grow on the neck, and the buds grew sturdily day by day.
Cactus has a strong vitality.
In the hot desert, it is like a "guard", motionless, no matter your suffering or fire, it is as straight as straight.
Cactus can have many uses, it can be used for viewing; It can fix sediment and protect farmland.
It can also be used in food and medicine.
One day, my mother's feet were crooked and swollen like a steamed bun. Grandma broke off a cactus and smashed it on my mother's foot. After a few days, my mother's feet gradually swelled up.
Although cactus is not accompanied by gorgeous colors and flowers, it can purify our air, inhibit the production of carbon dioxide, and heal other people's wounds with its own limbs. Cactus is really a plant that benefits mankind.
We should also be like a cactus: in life, learn the ability to live independently and constantly hone our will; In learning, we should persevere, dare to endure hardships, learn more knowledge, and make ourselves a "treasure" like cactus in the future and make contributions to society.
An essay about writing 800 words about cactus: cactus has no flowers that people envy at first sight, nor does it have a colorful body.
It is covered with needles, which makes people feel chilly at first sight.
How admirable is its noble quality of obscurity and selfless dedication! Potted cactus, its indomitable character is very surprising, it doesn't care whether there is water, whether the weather is hot or not, whether it is cold or not.
Its green body has palm-shaped stems covered with thorns, and it does not keep growing upward, like a pyramid-shaped ocean.
A piece of "green palm" grows a piece of "small green hand", which makes people have a lot of reverie.
It looks like this everywhere.
In the hot and long drought summer, other potted plants have bowed their heads, but cactus looks up at the blue sky like a soldier; In the severe winter, other potted plants have already been brought back indoors by their owners, but cactus has experienced wind and rain and is not afraid of the surrounding environment.
It never pays attention to it. It has been rooted all its life, as if to say, "This place is really nice. Let's grow up here! " The immortal is covered with hard thorns, and any wild animal will stop at once when it sees it.
Pests want to bite it, and their bodies are always full of holes.
As soon as the green cactus came out of the ground, everyone thought it was dead. No, if you do this, it's wrong. It uses the nutrients of the body to take root and sprout and cultivate a young cactus. This is the real "rooting".
Who can match its tenacious vitality? This seemingly ordinary plant, who would have expected, will produce beautiful flowers, just like colorful tassels on a samurai helmet.
Cactus is a tropical plant. It is shaped like a palm, hence its name.
It is not afraid of heat, that is, the temperature is as high as 40 degrees Celsius, and it can survive tenaciously without drinking water for several days.
In this way, day after day, month after month, year after year, it has withstood the test of the scorching sun and grown happily.
People should also have this indomitable spirit, and live and work with a strong will regardless of good times and bad times.
Cactus is also a good medicine. It helps when people are sick. For example, if they get mumps, mash it with stones and smear it on their cheeks, and they can be cured quickly.
Cactus has no flowers that people admire at first sight, and it has no colorful body.
It is covered with needles, which makes people feel chilly at first sight.
How admirable is its noble quality of obscurity and selfless dedication!
This composition about the discovery of plants is about 400 words. Thank you, everyone has their favorite plants, and I am no exception. My favorite plant is chlorophytum. Although the flowers of Chlorophytum are not as charming as roses, they are not as elegant as plum trees. However, it also has its own unique charm. In the old chlorophytum, there will be many small chlorophytum. When the little chlorophytum grows big enough, it can be transplanted. You can also soak in water. It will take root, sprout and thrive. My chlorophytum has been in the water for more than three months. When the breeze blows, it will show a beautiful dance, like an excellent dancer. Small chlorophytum was yellow-green when it first came out, and its leaves were tender like a baby's face. In a few days, the leaves will gradually turn pale green, and when it grows up, it will turn green and give off. Its flowers are beige and small. Although they are not so fragrant, they also have their own charm. It should be said that watering chlorophytum is the most interesting time. The small water drops spilled on the ground rolled to the ground, like an elf riding on a green slide, and the leaves with green light became greener. Chlorophytum can also release oxygen, recycle waste gas and make the indoor air fresh, which is most suitable for keeping at home.
About my discovery composition 400 words I found ants. Sometimes, maybe you will find that there are always some "lazy ants" among the swarms of ants. Other ants work very hard, busy in and busy out. But what about these "lazy ants"? No wonder people call them "lazy ants", because they don't go out for food, they do nothing all day and look around.
However, the fact tells people that it is this lazy ant who idles all day, after the ant colony cuts off the food source, and when those ants who usually work hard are at a loss, they "step forward" and lead their partners to move to the new food source it has detected.
Although lazy ants don't work, they use their wisdom to get everyone out of trouble in times of crisis. It can be said that their contribution is greater and more commendable than that of hardworking ants.
A biologist once divided all lazy ants into several groups and put them together. As a result, 80% of lazy ants become hardworking ants, but 20% of ants are still lazy. All the ants in their original ant colony stopped working and were in a mess. Until those lazy ants were put back, the whole ant colony resumed its busy and orderly work.
It can be seen that lazy ants are indispensable in the whole ant colony! Lazy ants spend most of their time on "reconnaissance" and "research".
They can observe the weakness of the organization, have the ability to maintain the survival of the ant colony in difficult times, can avoid putting all the ant forces into the work of carrying food, and at the same time keep exploring new foods, thus ensuring that the ant colony can continuously obtain new food sources.
It is important that diligent ants exist, but only when diligence and laziness complement each other will the whole group become stronger.
The principle of diligence, laziness and laziness, laziness is not necessarily a survival wisdom.
If you are lazy to do housework, you can be diligent in thinking.
Sometimes, as a student, you don't have to care too much about the trivial things in life, and you don't have to be obsessed with learning. There is no need to engage in sea tactics. Only by learning to analyze, learn to think and know what things are can we be more calm in the face of life and study.
There is a saying that "people who attend are not busy, and busy people will not."
Only by jumping out of the narrow vision can we find the key to the problem.
Learn the spirit and way of lazy ants, and stand tall to see far.
The composition "Praise cactus" praises cactus in 500 words. Although ordinary, it has tenacious vitality. The hometown of cactus is a perennial drought area, and the poor natural conditions have eliminated the weak. Cactus is a strong plant, and it is almost immortal. Whether lonely or forgotten; No matter in contempt or other unfair treatment, cactus always keeps its true colors. It doesn't care about other plants, and it doesn't compete with other plants for fame and gain. It dedicated itself in obscurity, adding a touch of bright color to the desert. I was moved by its indomitable spirit and thought a lot. I don't know when it came to the desert, shed its proud green branches and covered it with thorns like steel needles. It despises snakes and mice and lives in the desert. As long as they are alive, cacti will hold their heads high. It tells all the difficulties that we are invincible. As long as people come here, they will selflessly give their precious lives to quench their thirst. In life, some people have the same tenacious and valuable spirit as cactus. I thought of Cui Renzan, a classmate in our class. She praised her last term. However, it has tenacious vitality. The hometown of cactus is a perennial drought area, and the poor natural conditions have eliminated the weak. Cactus is strong, it is almost immortal, whether it is lonely or forgotten. No matter in contempt or other unfair treatment, cactus always keeps its true colors. It doesn't care about other plants, and it doesn't compete with other plants for fame and gain. It dedicated itself in obscurity, adding a touch of bright color to the desert. I was moved by its indomitable spirit and thought a lot. I don't know when it came to the desert, shed its proud green branches and covered it with thorns like steel needles. It despises snakes and mice and lives in the desert. As long as they are alive, cacti will hold their heads high. It tells all the difficulties that we are invincible. As long as people come here, they will selflessly give their precious lives to quench their thirst. In life, some people have the same tenacious and valuable spirit as cactus. I thought of Cui Renzan, a classmate in our class. Last semester, she was. Her mother has cancer, and it has reached the terminal stage. We learned all this from our teacher, so we agreed to visit her home. As soon as I entered the door, I was shocked by what I saw. I have never seen such a poor family, a low bungalow, no furniture in the house, only a shabby bed, a table with nails in all corners and an old chair. That's where Cui Renzan eats and studies. Her mother is seriously ill, and she has to take care of her mother to do her homework and study, and then eat, even if she is hungry after going home every day. If I hadn't seen it with my own eyes, I wouldn't believe that a sunny and confident girl should bear such a heavy burden of life. Last semester, she ranked first in her class with a score of 100 and 99.5, which was achieved in such a harsh environment. I am deeply shocked. Difficulties did not knock down the tenacious girl. Isn't she like a cactus in the desert I learned a lot from Cui Renzan: a person's potential is great. No matter how difficult it is, as long as he persists, he will certainly overcome it. Franklin once said: "I have never seen a person who gets up early and works hard complain about bad fate;" Good character, good habits and strong will will will not be defeated by the so-called fate. " Anyone may encounter a difficult living environment, but not everyone can be as strong as a cactus. After going through difficult tests and tribulations, I can still keep a grateful heart and be willing to pay for others. They are like the most respectable people.
Cactus is amazing. I like flowers best. In order to green the environment, my parents bought some pots of flowers from the market and put them on the balcony.
There is also an unremarkable cactus. Why is it called "cactus"? I don't know, maybe it's called "cactus" because its shape is different from human limbs.
"Every morning, I water the flowers a little, because if I water them too much, they will die easily.
I also heard that cactus doesn't like drinking water very much, so I water it every three or four days.
My cactus is dark green and full of thorns, probably because it is not disturbed by the outside world, so there are many thorns on it.
A cactus, a bit like the shape of a cucumber, is connected together, and some hold together like brothers and never part.
In spring, the grass sprouts, the flowers bloom and the drizzle is fragrant, which constitutes a beautiful and perfect spring scene.
But who can notice cactus? It does not covet fame and fortune, and never gives in to difficulties.
Sometimes I also find that there are countless cracks in the soil of cactus, and the soil is rough and dry, but it doesn't mind and still stands on a colorless ceramic basin made of soil.
What is this for? In order to contribute to the world, add green to the world, absorb carbon dioxide, release fresh air and make the environment fresher.
Although this flower is beautiful, it is too fragile and easily broken.
Gradually, I fell in love with cactus unconsciously, because its noble quality has always attracted me.
Cactus is a desert plant and I admire its tenacious vitality.
Let's take a look at its introduction first! Cactus is dark green all over. If you look closely, you will find clusters of white thorns on its oval thick stem.
This little thorn is its leaf. If it stings you, you will "ouch" for a while.
This may be its weapon to protect itself.
Although the cactus looks ugly, if it is open, it is better than Bai Mudan, as if it is decorating itself.
Flowers as white as jade are also fragrant, which really makes people want to pick one.
But at this time, the small thorn will remind you "just look, don't start work!" Although the flowering period of cactus is very short, it will wither in only one day, but its vitality is very strong.
Whether summer is "scorching sun" or not, as long as it is planted in the soil and left unattended for a few days. Even in the "freezing and snowing" winter, it will not change color and grow tenaciously.
Cactus is a cactus, which is the general name of spherical species of cactus plants. It is not only varied and complex, but also has unique and colorful shapes. It is a pearl in a hundred flowers garden.
If you pay attention to the taste, you can plant some kinds of cactus, such as Jinhu, Feipeony, Dragon Ball and Moon Palace.
However, those ordinary cacti also have a "taste". They have strong habits and are easy to cultivate. Flower pots, pottery pots, porcelain pots, purple sand pots and plastic pots are all acceptable. The fertilizer is the residue of plant ash, Taomi water and yogurt.
I hope you don't underestimate cactus. Although the variety is common, the flowers are still beautiful and will not disappoint people.
However, what makes people sigh is not the beautiful flower season of cactus, but the breeding period of its big balls and small balls. Watching the little balls attached to the mother gradually change from small to big, the thick maternal love is also very touching.
When the melon is ripe, these young eggs will leave the mother's body and open up their own world. Although I am silent, people who like to grow cactus will certainly not turn a blind eye to all this (I am just stupid and can't describe it).
A horizontal couplet depicts the following: the baby fell to the ground.
I think it is not only vivid, but also full of puns and fun.
Haha, there are actually many kinds of cactus, so I won't introduce them here.
