Commonly known as grass ball, also known as longevity ball, is a perennial succulent and pulpy herb of Xiancaoke. The stem is spherical or oval with a height of 25 cm. It is green, the sphere has several longitudinal sides, and there are many needles on the sides, which are yellow-green, different in length and radial. Peanuts are spiny, silvery white or pink, long trumpet-shaped, up to 20 cm long, with scales outside the trumpet and long hair on the scales. Cactus usually bloom in the early morning or evening, lasting for several hours to a day. Many small balls are often born on the side of the sphere, which is beautiful and generous.
From the appearance, cactus can be divided into velvet, wart, treasure, hair column, strong thorn, sea urchin, top flower and so on. The prickles of cactus are also long, short, thin and dense; Mao Yan has red, yellow and gold.
Cactus is loved by people because of its peculiar shape, delicate color and easy cultivation.
Characteristics of cactus
Cactus is a dicotyledonous plant, belonging to Cactus family in plant taxonomy. There are many kinds, about 40 varieties, such as spherical stems, ellipses, longitudinal prisms and other different spheres, which are arranged radially; The length and density of bristles are different; The colors of flowers are gold, white and red. In spring and summer, big and long trumpet-shaped flowers bloom from bulbs. Small balls can grow on a sphere.
The hometown of cactus is in South America, which is native to the desert with high temperature, dryness and little rain, and has formed the characteristics of dryness and drought tolerance. Cactus is afraid of cold and likes to be born in well-drained sand. Summer is the growth period and flowering period of cactus.
How to cultivate
1 Potted plants are generally used to grow cacti at home. The cultivated soil consists of 5 parts of humus, 3 parts of sand and 2 parts of sugar ash. It's best to add a little bone powder and mix it evenly before planting.
In spring and summer, cactus begins to grow, and it is best to apply fertilizer once every half month, and it is best to mix nitrogen, phosphorus and potassium. In addition, it is necessary to properly shade the sun and not to be exposed to the scorching sun.
Potted cactus should be moved indoors in winter, and the room temperature above 5℃ can safely overwinter. At this time, the family potted cactus can be placed in an indoor glass jar to keep warm for the winter, or it can be wrapped in a double plastic bag to keep warm for the winter. In winter, cactus is in dormancy, so the soil in the basin should be relatively dry, otherwise it is easy to rot the roots.
How to graft
There are two kinds of grafting propagation of flowers: branch grafting and bud grafting. There are many grafting methods, such as cutting, splitting, inserting, flat grafting, tongue grafting, docking and so on. Cactus is butt-jointed, and the specific methods are as follows:
The grafting time of cactus can be carried out in May 5- 10/0, and the best time is May-June and August-September. Sterilize with alcohol cotton ball with a knife, and cut a fairy triangle (another cactus plant) with a length of 12 cm. Insert it into a pot filled with culture soil, gently compact it around, thoroughly sprinkle with clean water, move it into a glass cover, or cover it with a double-layer plastic bag to observe whether the fairy triangle planting survives.
After planting a living fairy triangle, use an alcohol cotton ball disinfection knife to cut off the sub-balls of the fairy ball, cut them flat at the bottom 1/3 or 1/4, put the sub-balls on the catheter of the fairy triangle, and gently move them left and right until they are glued. It is best to tie the two together with thread to make them closely combined. After grafting, put the pot in the shade and keep it out of the sun for three or four days, and you can manage it normally. At this time, the cactus has been grafted successfully.
Palm bonsai
Bonsai is the reappearance of strange and beautiful mountains, water, flowers and grass in nature. According to the size of bonsai, it can be divided into large bonsai, general bonsai and miniature bonsai. Miniature bonsai is a miniature bonsai. This kind of bonsai is small and exquisite, lush and has a unique flavor. Cactus has strong adaptability and high survival rate, and is a good material for making pocket bonsai. Here are two ways to make hand-cranked bonsai.
1 Take out two and a half ping-pong balls from the giraffe bonsai, with one mouth facing up and the other mouth facing down, and stick them with "502" glue. Then the top half of the table tennis shell is filled with culture soil, and cactus grafted with cactus is planted in it, which becomes a billiard shell bonsai shaped like a giraffe.
Single hill pavilion bonsai takes a small plastic box cover as a basin, and a small hole is burned in the center of the basin bottom, which is a leakage hole. Next, stick three toothpaste covers on the appropriate position of the basin bottom as the foot of the basin. Finally, put the culture soil in the basin, plant the cactus with moderate size, and put a small pavilion on the top of the cactus to become a "single mountain pavilion". Put a few pebbles of different sizes in the basin as a foil to add beauty and realism.
The cactus has blossomed.
Cactus is usually cultivated for 3-4 years, and should be able to bloom when its diameter reaches 3-4 cm. To make cactus blossom, we should pay attention to the following points:
Sunlight cactus needs sunlight as a substitute, so it will be kept indoors for a long time. Without sunshine, there would be no flowers.
Temperature cactus needs warmer environmental conditions. If the environmental temperature does not reach above 20 degrees, it will not bloom.
Second, water must not be poured too much, so that the basin soil is too wet, but it should be dry and not wet. Especially in winter and summer dormancy period, water should be controlled.
3. Fertilized cactus is barren and drought-resistant, and it is not easy to bloom in the case of drought and lack of fertilizer. Therefore, proper water and fertilizer should be given in cultivation, and thin and decomposed cake fertilizer should be applied every 10 day to half a month in the growing season. Fertilization should not be excessive, and excessive fertilization will also lead to no flowering.
Pay attention to create a local environment with suitable temperature and high humidity for cactus, for example, make a closed shed with plastic film on the windowsill and put the cactus in it for maintenance, so that it not only grows faster, but also has bright colors and is easier to bloom.
My practice is this: the flowerpot is placed on the balcony, with plenty of sunshine and good air circulation. Before the first frost every year, cover it with plastic shed to winter safely and avoid freezing injury. After the Spring Festival and before Tomb-Sweeping Day, the old soil was removed and replaced with chicken manure 15% because the ball was prickly and it was difficult to change pots. Bean cake 10%, hydrated lime 10%, plant ash 5%, sawdust 5%, coarse sand or honeycomb coal 15%, and garden soil 40%. During the growth period, it is necessary to increase fertilizer water in time, topdressing with bean cake liquid and fishy fertilizer water, spraying 0.2% potassium dihydrogen phosphate outside the roots, or applying phosphorus and potassium fertilizer to master the principle of dry and thorough watering.
Environmental protection function of cactus
(cactus-anti-radiation)
In life and work, planting a cactus can absorb electromagnetic radiation. The breathing hole of cactus, which is opened at night, can release a lot of oxygen while absorbing carbon dioxide. Placing this plant next to electrical appliances at home or office can effectively reduce the electromagnetic radiation pollution caused by various electrical and electronic products and increase the concentration of negative particles in indoor air. Therefore, placing this plant next to electrical appliances at home or office can help the human body to minimize the radiation released by computers. There is also a saying in Feng Shui that placing large potted plants with sharp leaves on the balcony can avoid misfortune.
(cactus-natural oxygen bar)
Most cacti breathe in cool and humid nights. When breathing, inhale carbon dioxide and release oxygen. So putting a monster like Jin Hu in the room is tantamount to adding an air freshener, which can purify the indoor air. Therefore, it is also an ideal flower for indoor night decoration.
(cactus-vacuum cleaner) Don't underestimate cactus, they are still experts in vacuum cleaning! Placing a cactus indoors, especially hydroponic cactus (because hydroponic cactus is cleaner and more environmentally friendly), can purify the environment.
