To cultivate orchids, we should first solve the environmental problems of orchid planting sites. Orchid planting can be divided into courtyard planting and large field planting. General family orchid can choose balcony or rooftop, you can also build a shed on the windowsill. Glass greenhouses can be built if conditions permit. But the planting place no matter in the balcony, the roof or the windowsill, must have the appropriate shade, the ventilation condition, maintains the appropriate humidity, this is the foundation of planting orchids. Planted in the balcony, to choose to sit north to south balcony, you can use a mobile sunshade net to block the wind and heat, such as the sky with zinc iron awning is best transformed into imported transparent rubber tiles to ensure that the right amount of sunlight. Rooftop orchids can be supported by water pipes, and 80% shading nets are used around and on the sky to block the sun and wind. When it is too hot in summer, add a movable sunshade net to the roof. Generally speaking, environmental transformation should be adapted to local conditions and should be constantly explored and improved through practice.

Choose good plant materials and pots for orchid cultivation, which is the basic condition for planting orchids. Orchid pot is the living room of orchids, which has a great influence on the growth of orchids. In the past, traditional orchids used large tile pots, most of them used small trumpet pots in growing high-grade orchids, and there were pottery pots and plastic pots, each with its own advantages and disadvantages. What kind of pot to use depends on each person's habits and varieties. But in an orchid shed, it is best to use an orchid basin of the same texture. (there are different sizes and specifications) for unified management in the future. Orchid plant materials (base materials) used to use pond mud in the past, but now the fine products are converted to pond cornerstones, pumice, wind fossils, absorbent stones, ceramsite and so on. Field species of orchid mostly use sawdust, grain husk, dregs, cinders, sea sand, peanut shells and other soft plants, with foam at the bottom. Mixed use is more common. The use of these plants has its own advantages and disadvantages.

To cultivate orchids, we should constantly sum up experience in practice. Experience is the best teacher. In order to improve the level of orchid cultivation, we must personally participate in the practice of orchid cultivation. At the beginning, we should read more books, visit more, ask more questions, and constantly explore and sum up experience and intensive training in practice in order to continuously improve the technical level of planting orchids.

Mastering the management techniques of watering, fertilization and pest control is the key to the cultivation of orchids. Fertilization should generally be applied in sunny days, and the principles of fertilization should be applied thinly, frequently and not during hibernation. In order to facilitate beginners to master the orchid, the cultivation of Cymbidium and Jianlan in Guangdong, Guangxi, Fujian and Hainan in southern China are introduced as follows.

January: watering should be in the morning. One and two times of insecticidal and sterilization, and foliar fertilization for 1 and 2 times.

February: pay attention to disinfection, sterilization and disinfestation. But fertilizer, medication must be extra careful, in case the fat medicine is too strong and hurt the bud. In fertilization, we should pay attention to the proper amount of organic fertilizer to stimulate the vitality of new buds.

March: it is the Spring Equinox when the weather is getting warmer, animals and plants begin to wake up after hibernation, new buds come back, pay attention to replenishing organic fertilizer and increasing daylighting, insects and bacteria begin to move, and attention should be paid to disinfestation and sterilization (see the instructions for the use of pesticides first).

April: entering the plum rain season, diseases such as soft rot, black spot, anthrax and so on are easy to occur. Therefore, special attention should be paid to sterilization and disease prevention, and the foliar should be sprayed 1 or 2 times. Pay attention to prevent the accumulation of water and fertilizer in the heart of the plant from causing soft rot, and let the orchid plant be ventilated and transparent.

May: the sun is getting stronger, pay attention to proper shading. Pay attention to prevent the emergence of insect pests in new buds. Orchids grow rapidly this month, so more topdressing should be applied, but not too thick.

June: the plum rain season is over, and the summer heat is at the beginning of steaming, so it is not suitable to divide plants and change pots casually. Watering should depend on the degree of dryness and wetness of the basin soil, and wetting is appropriate. Spray in the morning and at night and sprinkle the leaf surface twice. Pay attention to increase the humidity of Orchid Garden. Insecticidal and sterilization should be carried out in a cool night. The dose should be thin and must not be concentrated.

July: in the weather season of Lesser Heat and Greater Heat, we should pay attention to the cooling of sprinkled wetlands and ventilation luck. The degree of shade should be increased. Cymbidium, Cymbidium and Cymbidium can be added to organic return, and cold orchid can spray water and fertilizer.

August: autumn begins, and this month we should pay more attention to heat prevention and cooling. Insecticidal and sterilization should still be carried out at night, and the orchid garden should be thoroughly disinfected once. This month is the period for the emergence of autumn buds, and after the hot and hot weather, the nutrients in the basin are gradually consumed, so we should pay attention to increasing organic fertilizer and foliar spraying fertilizer twice to facilitate the growth of autumn buds.

September: summer heat is the most popular, all kinds of orchids are most afraid of open-air exposure, so they should spray more water. Shell insects, spiders and other pests are increasingly rampant, soft rot is easy to occur, more attention should be paid to insecticidal sterilization, but the use of drugs should be appropriate.

October: autumn sun can enhance the rigidity of orchid leaves, therefore, we should pay attention to increase the amount of daylighting, according to the situation to increase the number of watering. In addition to flowering orchid plants, fertilize 2-3 times this month, and pay attention to strengthen sterilization. Watering principle: look at the weather and air humidity, plum rain weather is not watered, Greater Heat weather is cold in the morning and evening, and at noon in winter.

November: watering and spraying was carried out in the morning, killing insects and sterilization twice to eradicate the hidden danger of orchid plant disease. Be sure to read the drug instructions clearly for insecticide and sterilization.

December: this month is the best time for Mulan to choose flower art, see flower trade, take flower as treasure. This month, insecticidal sterilization is still carried out one or two times, watering should depend on the dry humidity of the basin soil, watering should be carried out in the morning on a sunny day. Guard against cold and frost. The basin change should be completed before the end of this month.
