Why did the domestic flower die?
(3) People often put potted flowers on the closed balcony facing east or west, so the temperature in the balcony rises sharply due to the radiant heat of the sun, forming a hot and dry environment. High temperature, dry heat and insufficient ventilation are prone to the harm of red spiders, which accelerates the death of flowers.
(4) The overwintering flowers suddenly leave the room to overwinter indoors, and the leaves they grow belong to semi-shade leaves or shade leaves. When they suddenly leave the room in early spring, the shady leaves can't adapt, and the young leaves and buds are easily burned by the sun. In addition, the temperature difference between indoor and outdoor is large, which is easy to cause fatal damage to flowers.
(5) Lack of sunshine Some people put flowers indoors and away from the sun for the convenience of appreciation, so that their photosynthesis is inhibited, and the organic nutrients in flowers can only be consumed but not replenished in time, which reduces the resistance of flowers and makes plants weak and die. Too much watering is also the cause of plant death.
Family knowledge of flower cultivation
The secret of family flower cultivation is mainly to provide flowers with the growth conditions they need, especially in the dry climate in the north. Only by creating a microclimate suitable for growth can the flowers in the south grow well and flourish. The following are some key points of potted flower cultivation for family growth. Rhododendron: Rhododendron is one of the representatives of acid-loving plants, and likes cool, humid and well-ventilated environment. The suitable growth temperature is 13℃ to 25℃, the relative humidity of air should be kept at 60% to 70% during the growth period, and the relative humidity can reach about 80% when flowering. Rhododendrons like light, but avoid direct glare. Shading should be appropriately increased in spring and autumn, and it should be around 70% in midsummer. Rhododendrons should be placed outdoors for ventilation in summer. During the growth period, apply thin fertilizer frequently, preferably farmyard manure, and prune the flowers when they fall down.
Ruby: A large perennial evergreen vine of Araceae. I like warm and humid environment and prefer light and shade. The optimum growth temperature is 15 ~ 25℃, and the minimum overwintering temperature is not lower than 5℃. I like loose and fertile soil rich in organic matter. In the growing season, I like big water and big fertilizer. Maintain in the semi-shade, pay attention to watering, but the soil in the basin should be dry and wet, and no water can accumulate. During the growing season, it is appropriate to apply 1 times of decomposed cake fertilizer or alum fertilizer every 10 day. The overwintering temperature should be kept above 5℃.
Emerald: a large perennial vine of Araceae. Emerald and ruby have the same habits. But higher temperature and humidity are needed. The optimum growth temperature is 20 ~ 30℃, and the overwintering temperature is not lower than 65438 03℃.
Arundo donax: A perennial evergreen herb of Arundinaceae. Potted soil can be mixed with humus soil and peat soil in equal amount. Proper watering in the growing season will keep the basin soil moist, but too wet will cause root rot. Apply 1 times pancake fertilizer every 2 weeks, and give sunshine and long-term shade in autumn and winter. Keep it dry in winter. If it is too wet, the leaves will turn yellow and brown.
Pineapple: a perennial evergreen epiphytic herb of pineapple family. I like a warm, humid and sunny environment and avoid direct sunlight in summer. The optimum growth temperature is 22 ~ 28℃, and the overwintering temperature should be kept above 65438 00℃. Always keep wet during the growing period, spray water on the leaves, and dry them properly in winter. The pancake fertilizer solution can be applied to pots and leaf tubes 1 ~ 2 times a month. In addition to shading in summer, there should be plenty of light in other seasons.
Brazilian wood; Evergreen erect shrubs or trees of Agavaceae. Prefer loose, breathable and well-drained soil to big fertilizer. During the growing period, soilless culture should be applied with 1 times pancake fertilizer water every month and 1 times nutrient solution every week. Shading should be about 50% in spring, summer and autumn to avoid direct sunlight and wind blowing, but too cool environment will lead to the pattern fading and falling off of leaves. Basimu likes humid environment, and the basin soil should keep a certain humidity, which will affect its normal growth.
Clivia: a perennial evergreen herb of Amaryllidaceae. Pleasant, warm, humid, cool and semi-cloudy environment. The optimum growth temperature is 15 ~ 25℃, and the optimum flowering temperature is 15 ~ 20℃. Cold resistance, high temperature resistance, water and humidity resistance, and a certain degree of drought tolerance. It needs loose and fertile slightly acidic soil with good drainage.
Milan: An evergreen shrub of Meliaceae. I like a warm, humid and sunny environment. When the temperature is above 25℃, it grows vigorously, and the flower ear is in the axil of the top leaf of the new branch. For fear of drought and cold, the wintering temperature should be kept above 65438 02℃. Loose and fertile slightly acidic soil is needed. During the growing period, the water should be dry and wet, not too much. Water should be sprayed on the leaves in summer to increase humidity. It is advisable to apply 1 double rotten cake fertilizer or alum fertilizer every two weeks. After flowering, proper pruning should be carried out, dead branches and over-dense branches should be cut off, and the branches in the center should be cut short and pitted to promote the production of a large number of side branches, which is conducive to the prosperity of flowers in the coming year. Winter requires outdoor and indoor maintenance above 12℃.
Cyclamen: Cyclamen is a flower that likes light and low temperature. The suitable growth temperature is 12 ~ 20℃, and the temperature should not exceed 30℃, otherwise it will be difficult to spend the summer. In order to make the buds flourish, it is necessary to give enough sunshine in the bud stage, put them indoors in the sunny place, and apply phosphate fertilizer once every 1 week. It is best to use 0.3% potassium dihydrogen phosphate compound fertilizer solution (containing trace elements such as zinc, boron, molybdenum, manganese, magnesium, copper, iron and sulfur), and the dosage of each pot is about 150 ml. Usually water 1 time every one or two days to make the basin soil moist. Never water the pot with big water until the soil is dry. However, the pot soil should not be too dry, which will cause root hair damage and plant upper wilting, and it is difficult to recover after watering again. The water temperature should be close to room temperature when watering.
Poinsettia: Euphorbiaceae. I like warm, humid and sunny, and I don't have strict requirements on soil, but I grow better in the slightly acidic (pH6) fertile sandy loam. Not cold-tolerant, it needs to be put into greenhouse before frost, and the optimal temperature is 16 ~ 18℃. When the temperature is lower than 15℃, the yellow leaves will fall off, so direct sunlight should be avoided in summer. This is a short-lived plant. Under the condition of 18℃ ~ 20℃ and 8 ~ 9 hours of light every day, flowers can bloom in about 50 days. Before and after Qingming, the dormant plants were replaced with pots and new culture soil was used. During the growing period, 1 ~ 3 times coring promotes multi-branches. 65438+ 10 was moved indoors at the beginning of October, and kept at about 20℃ and not lower than 15℃ at night, keeping a stable temperature and sufficient sunshine, so that the leaves changed color and blossomed.
Fortune tree: a newly introduced plant, which did not need to change pots or apply nitrogen fertilizer in that year, to control the overgrowth of young branches and prevent the tree from being crowned. Rich trees have strong adaptability to water. If you water outdoors or don't water indoors for more than ten days, there will be no floods and droughts that will cause the leaves to turn yellow. Water should be poured indoors every 3 ~ 5 days in summer and every 5 ~ 10 days in spring and autumn. Looking at the room temperature in winter, the soil in the basin is slightly wet. If the room temperature is around 12℃, you can water it once a month. It is resistant to both yin and yang and has strong adaptability. Under long-term weak light, the branches are thin, the petiole is drooping, and the leaves are light green. Do not change the yin and yang position of the basin in management. Sexually fond of warm environment, not cold-resistant, adaptable to growth temperature of 18 ~ 30℃. If the newly bought bonsai plants grow vigorously and the pots are too small, they can also be changed in July and August by using the semi-dormant state of the plants at high temperature. Do a good job of careful operation, so that the mother soil is not loose, and after planting, water is poured enough, which will not affect the growth. This tree species has strict requirements on basin soil and likes acid sandy loam and humus with good drainage.
Kumquat: keep the pot soil semi-dry and semi-wet, spray branches and leaves every three to five days to keep the leaves clean. Adequate water should be supplied in summer, and water should be sprayed once every morning and evening, but water should be properly controlled before picking new shoots, and dilute nitrogen-containing alum fertilizer water should be applied. The new buds germinate to about 10 ~ 15 cm, and the branches are topped at one time to make them full and mature. After the branches grow up, apply phosphate-containing alum fertilizer water to promote flower bud differentiation. After buds appear in leaf axils, flowers should be properly thinned, and 1 ~ 2 flowers should be left in each leaf axil. After fruiting, 3 ~ 4 fruits were left in the thick branches, and only 65,438+0 ~ 2 fruits were left in the branches, which made the whole plant evenly distributed and maintained more nutrition. After fruit setting, attention should be paid to removing autumn shoots to prevent secondary fruits. After fruiting, the soil in the pot should always be moist to facilitate the growth of fruits.
Rubber tree; Ficus of Moraceae. Evergreen trees and rubber trees like warm and humid climate conditions. Rubber trees are usually placed indoors in a semi-shady place, and too much direct sunlight is not enough. After arranging the position, don't move, because rubber trees have a stubborn primitive nature, but if they grow too vigorously in a certain direction, they can be changed appropriately and grow in a balanced way. Short-term temperature fluctuation is unfavorable to its growth, and the winter temperature is not lower than 65438 02℃. If stored at low temperature for a long time, excessive watering will lead to death. The amount of watering depends on the temperature. The water demand is large in spring and summer, and a small amount of water can be poured during the dormant period. Keep the basin soil moist and master the principle of wet but not dry. Fertilizer, mainly nitrogen fertilizer, should be applied every 10 day during the growth period. Stop growing or not applying fertilizer during dormancy. Change the basin every two to three years. The substrate is usually pastoral soil and peat soil mixed with a small amount of sand, and the soil is slightly acidic. Combine pruning when changing pots to promote the growth of lateral buds and make the tree shape complete.
Jin Xin Dictyophora: Dictyophora of Liliaceae. Perennial dwarf evergreen herbs like warm, humid and semi-cloudy environments. It will not affect the viewing effect if it is placed in strong light or dark place, and it can grow normally when the temperature is not lower than 7℃ in winter.
Aloe: Aloe in Liliaceae. Adapt to humid spring, dry autumn and winter, warm and sunny environment. In summer, it can be placed outdoors in sunny places. The sunnier the leaves, the richer the flowers. In winter, it should be placed in a place with good light and temperature above 5℃. The growth temperature in summer is 20 ~ 30℃. Water properly in summer and less in winter. Fertilize once every two weeks during the growing season. Change the basin every 2 ~ 3 years. The basin soil is humus soil, broken clay and perlite, and the ratio is 1: 1: 1.
Family flower cultivation skills
Flowers are the essence of nature. With their graceful charm and colorful fragrance, they are increasingly favored by people. Zhuhai is subtropical, and the climate is very suitable for families to grow flowers and grass. Bringing flowers into the family, breathing fresh air and enjoying endless fun has become a symbol of Zhuhai people's modern civilized life. However, it is not a simple matter to raise flowers well. Many flowers that could have grown for many years will soon wither and die because people don't know how to manage them. Therefore, we must carry out scientific cultivation management according to the actual family environment to reduce unnecessary losses. Reasonable watering
Water is a necessary condition for the survival and reproduction of flowers, and reasonable watering is the key to the success of flower cultivation. The variety, environment and climate of flowers are different, and the water demand varies greatly. Family flowers, especially indoor flowers in the living room, can't be watered too often because there is no direct sunlight, otherwise the soil is often in a waterlogged state and the roots will suffocate and die. Too much watering is an important reason why many families fail to raise flowers. Generally speaking, the flowers on the balcony should be watered more, and the flowers indoors should be watered less; Water more when the temperature is hot, and less when the temperature is cool. There are many herbs and few woody plants, which alternate between dry and wet, that is, water only when the soil is relatively dry, and water each time until water seeps from the bottom of the basin.
Timely fertilization
Family flowers generally don't need much fertilizer, especially popular foliage flowers such as Brazilian iron pillars and rich trees. In order to maintain the original plant shape and prevent growth and aging, fertilization is generally 65,438+02 times in the spring and autumn rainy season, and other vigorous flowers are generally fertilized once a month. Fertilizer can be sprayed with 500-800 times of NPK compound fertilizer, or self-made organic fertilizer, such as rice washing water and rice washing water.
Pollution-free pest control method
The main pests of flower cultivation in China are aphids, red spiders, scale insects, ants and grubs in the soil. Because general chemical pesticides are highly toxic, they are easy to pollute the environment and cause harm to the human body. It is best to catch it manually or spray it with self-made pollution-free anthers, such as adding a small amount of washing powder to garlic juice and diluting it 50 times; Or cut tobacco is soaked in 25 times of water for 48 hours, and a proper amount of washing powder is added to the filtrate, or 500 times of water and essential oil are added. It has obvious poisoning effect on general pests.
Family gardening pays attention to feng shui.
Many families will plant flowers, which can purify the air and bring good luck to their families. However, family gardening feng shui is also very particular. What matters should be paid attention to in how to place family flower feng shui? Here is some information about home gardening and geomantic omen. Let's have a look! Family gardening and feng shui pay attention to healthy home furnishings.
Pay attention to the flowers in the bedroom.
Although raising flowers at home has many advantages, we should pay attention to the arrangement of flowers in the bedroom, because during the day, flowers release oxygen and absorb carbon dioxide during photosynthesis; At night, flowers do not carry out photosynthesis, spit out carbon dioxide and absorb oxygen. At this time, if you put flowers in the bedroom, it will be harmful to your health. Therefore:
1, in the bedroom, it is best to put less or no flowers at night to avoid them competing for oxygen and affecting health;
Some flowers can not only freshen the air, but also have some negative effects on people, so it is best not to put them in the bedroom. For example, although Chinese rose will produce a lot of harmful gases, its rich fragrance will make people feel depressed and uncomfortable, hold their breath and even have difficulty breathing; For example, the leaves of rhododendron, tulip, lily and poinsettia can also absorb volatile chemicals, but the flower impurities of rhododendron yellow contain a toxin, which can cause poisoning if eaten lightly, and death if eaten severely (note: it is not sold in the market). Rhododendron mostly contains some volatile oil and rhododendron, which has certain curative effect on tracheitis and asthma. Tulip flowers contain a toxic alkali, which is reported to accelerate hair gel shedding if exposed for a long time. The fragrance of lilies will make people's center excessively excited for a long time, causing insomnia.
The following plants should not be kept indoors
Cordate telosma will emit a lot of waste gas after photosynthesis stops at night. This kind of waste gas smells good, but it is not good for human health. If left indoors for a long time, it will cause dizziness, cough, even asthma and insomnia. So, put the cordate telosma indoors during the day and move it outdoors at night.
Tulip flowers contain toxic alkali. When people and animals stay in this flower cluster for 2 -3 hours, they will feel dizzy and have symptoms of poisoning. In severe cases, their hair will fall off, so it is not suitable for planting at home.
Pollen emitted by Bauhinia Bauhinia can induce asthma or aggravate cough symptoms if people are exposed to it for too long.
The fragrant smell of flowers and trees such as pine and cypress can stimulate people's stomach. If you smell it for too long, it will not only affect people's appetite, but also make pregnant women feel uncomfortable, disgusting and dizzy.
The rich fragrance of Chinese rose will make people suddenly feel chest tightness and discomfort after smelling it, making it difficult to breathe. Sensitive people should not be cultivated indoors.
The fragrance of orchids can make people overexcited and cause insomnia.
Mimosin is a very toxic organic substance, and too much contact with human body will make hair fall off. The richness of Chinese rose flowers.
The fragrance will make some people feel chest discomfort, hold their breath and have difficulty breathing.
Nerium oleander can secrete a milky white liquid, and long-term contact will cause symptoms such as drowsiness.
The geomantic display of Chlorophyte is exquisite.
Orchids are hung in the kitchen.
The proportion of plants in the kitchen is second only to the living room, because some family members spend a long time in the kitchen every day, and the ambient humidity is also very suitable for most plants. In addition, the kitchens of ordinary families are mostly decorated with white or light colors, and stainless steel sinks. Colorful plants can soften tough lines and inject vitality into the kitchen. Usually located in a room facing north, there are few windows, and some potted plants can eliminate the feeling of cold. Because of the lack of sunshine, we should choose shade-loving plants. The kitchen is a workshop, with frequent operations, fragmentary articles, much smoke and high temperature, which is not suitable for putting large potted plants, but hanging potted plants is more suitable. Among them, chlorophytum is the best. Putting a pot of chlorophytum in the room can absorb harmful gases such as carbon monoxide, carbon dioxide, sulfur dioxide and nitrogen oxides in the room within 24 hours.
It acts as an air filter.
Hanging orchids in the bedroom
Bedrooms are usually clean, quiet and warm. Chlorophytum, lily, tuberose and calla lily are all acceptable. It can make the relationship between husband and wife harmonious, and both body and mind can rest in warmth and tranquility. Chlorophytum is one of the most traditional indoor hanging plants because it is easy to cultivate and has strong adaptability. Its leaves are slender and soft, and small plants are pulled out from the axils of leaves, which droop from the edge of the basin, stretching and drooping like flowers, and are evergreen all the year round. Chlorophytum is the king of in addition to formaldehyde among plants.
Home flowers should pay attention to the secret of feng shui.
Don't be greedy for perfection.
Family flowers should be selected according to the size of the room, with moderate plant type and beautiful appearance, which is harmless to the family. Some flowers contain toxins, such as Du Juanhua and Bauhinia. Once eaten by mistake, people may be poisoned. When daffodils, dripping Guanyin and other leaf juices and flower juices are dyed on the skin, they can cause allergic symptoms such as redness, swelling and pain. Therefore, special attention should be paid to management, and it should be kept out of the reach of children.
Avoid children playing or eating by mistake. Plants with spikes will pose a certain threat to human safety and should be kept away from family activities.
Growing flowers indoors is not as much as possible.
In a room of about 15 square meters, you only need to put 2 pots of medium and large plants and 3 ~ 4 pots of small plants. In addition, in order to build a green oxygen bar in the living room, we should not only consider the plant type and color of green plants, but also consider the way they absorb carbon dioxide. Some plants belong to the category of consuming oxygen and releasing carbon dioxide at night, so it is best to go outdoors at night to avoid competing with others for oxygen and affecting health.
Don't plant flowers in the ward and bedroom at night.
Many flowers have the function of purifying the air and promoting health, but if some flowers are raised at home, they will become pathogenic sources or killers, leading to the recurrence and aggravation of old diseases. Therefore, experts suggest that you must know the nature of flowers before planting them to prevent mistakes.
Patients should not keep potted flowers indoors, because the soil in the flowerpot will produce fungal spores. When they diffuse into the air, they can easily invade human skin, respiratory tract, external auditory canal, meninges and brain, causing infection, which is very harmful to patients with existing diseases.
It is not suitable to put flowers in the bedroom at night because most flowers absorb carbon dioxide and release oxygen through photosynthesis during the day, but the opposite is true at night. Therefore, it is best not to put flowers in the bedroom. Flowers planted during the day will be moved out at night, at least not in the bedroom, so as not to affect the health of family members.
Disinfectant: volatile oil produced by fragrant flowers such as rose, osmanthus fragrans, violet, jasmine, lemon, rose, carnation, lily of the valley and crape myrtle. Has obvious sterilization effect. Crape myrtle, jasmine, lemon and other plants can kill diphtheria, dysentery bacteria and other protobacteria within 5 minutes. The scents of roses, carnations, lilies of the valley, violets, roses, osmanthus flowers and other plants have obvious inhibitory effects on the growth and reproduction of mycobacterium tuberculosis, pneumococcus and staphylococcus.
Natural oxygen generator: succulent plants such as cactus, which are native to tropical arid areas, have their stomata closed during the day and open at night. While absorbing carbon dioxide, they produce oxygen and increase the concentration of negative ions in indoor air. Plants such as Hupilan, Huweilan, Tequila, Palm, Kale, Sedum, Rooting and Pineapple can also purify the night air.
Air scavenger: Aloe, chlorophytum, Eupatorium odoratum, Eupatorium odoratum and Phyllostachys pubescens are natural scavengers, which can remove harmful substances in the air. Studies show that Eupatorium adenophorum and Eupatorium adenophorum can absorb more than 80% of indoor harmful gases, and their ability to absorb formaldehyde is super strong. Aloe can absorb 90% formaldehyde contained in 1 m3 air; Ivy, Cycas, Chrysanthemum, Kumquat, Pomegranate, Scutellaria barbata, Camellia, Milan, Daisy, Chimonanthus praecox and Marigold can effectively remove harmful substances such as sulfur dioxide, chlorine, ether, ethylene, carbon monoxide and nitrogen peroxide.
Natural vacuum cleaner: sweet-scented osmanthus, wintersweet, cauliflower taro, sweet-scented osmanthus, etc. They are natural dust collectors, and their cilia can intercept and absorb floating particles and smoke in the air.
Spiritual synergist: Lilac, jasmine, rose, violet, mint and other plants can make people relaxed, conducive to sleep and improve work efficiency.
Effective disease prevention: the fragrance of rose, carnation, lily of the valley, violet, rose, osmanthus and other plants has obvious inhibitory effect on the growth and reproduction of tuberculosis, pneumococcus and staphylococcus.
Air conditioning cooling competition: planting climbing plants such as Parthenocissus tricuspidata, grapes, morning glory, wisteria, roses, etc. Around the home, and let them climb along the wall or along the shelf to form a green arbor, which can effectively reduce sunlight radiation and greatly reduce the indoor temperature.
The following plants should not be kept indoors
Cordate telosma: When photosynthesis stops at night, a lot of waste gas will be discharged. This kind of waste gas smells good, but it is not good for human health. If left indoors for a long time, it will cause dizziness, cough, even asthma and insomnia. So, put the cordate telosma indoors during the day and move it outdoors at night.
Tulip: flowers contain poisonous alkali. People and animals stay in this flower for 2 -3 hours, and they will get dizzy and have symptoms of poisoning. In severe cases, their hair will fall off, so it is not suitable for planting at home.
Bauhinia: It emits pollen, which can induce asthma or aggravate cough symptoms if people contact it for too long.
Pine and cypress: The fragrant smell of this kind of flowers and trees can stimulate people's stomach. If you smell it for too long, it will not only affect people's appetite, but also make pregnant women feel uncomfortable, disgusting and dizzy.
Chinese rose: the rich fragrance will make people suddenly feel chest tightness and discomfort after smelling it, making it difficult to breathe. Sensitive people should not be cultivated indoors.
Orchid: Its fragrance will make people overexcited and cause insomnia.
Mimosa: Mimosin is a very toxic organic substance, which will make hair fall off if it comes into contact with human body too much; The rich fragrance of Chinese rose will make some people feel uncomfortable in the chest, hold their breath and have difficulty breathing.
Nerium oleander: It can secrete a milky white liquid, which will cause drowsiness and other symptoms when exposed for a long time.
