Orchid is a perennial evergreen epiphytic flower. It has a unique flower shape, beautiful flower posture, and the price is relatively high, so it has become a cherished flower variety.

Cutting stalks to promote sprouting of all kinds of orchids, especially Cymbidium (Orchid), should cut off the stem of the withered flowers as soon as possible, and do not let them bear fruit, so as not to consume nutrients and affect the germination of axillary buds. After the pedicel is cut off, 0.1% omethoate or dichlorvos solution is dipped in soft gauze or cotton ball, and the leaf surface and back of the orchid are gently rubbed to remove eggs, dust and stains to welcome the new growth period.

Before all kinds of orchids are put on the pot, the water supply should be stopped for 5 days. When the plant material in the pot is 70% to 80% dry, carefully pour out the orchid plant and the pot soil, so as not to let the orchid root break as far as possible. After removing the rotten roots, each plant is divided into mother gladiolus, autumn orchid and cold orchid, Xia Hui and Chunlan, each group is divided into about 5 gladiolus, first washed with disinfectant or clean water, the orchid root and wound can be point with sulfur powder, and then dry, wait for the orchid root to soften and whiten and then put on the basin. Apply fertile and sterile new plant material to the upper basin soil, and make sure that the plant material must protect the root and stick the plant material, the new plant is outward, the old plant is inward, and the depth is 1 inch 3 degrees when the orchid head is exposed to the soil surface. Put the pot soil on the plant and put it in the shade shed, spray a little fog on the leaf sooner or later, wait for the wound to heal after 24 hours, then pour enough water to fix the root. After 15 days of potting, it can be transferred to normal management.

Although half flowers like a cool and ventilated environment, they also need necessary sunshine. If the potted orchid is placed in the shade all the year round, the leaves will grow, the flowering will be rare, and the organs of the orchid plant will become weak and prone to diseases and insect pests. Therefore, it is necessary to adjust the light reasonably to facilitate its robust growth. Generally speaking, green leaf products, strange flowers and dwarf species need 60% of the full sunshine in spring and 50% in the future, while line magnolia needs 50% in spring and 30% in the future. In order to adjust the light, professional households of flower production can be cultivated in sheds, families with conditions can build an orchid shed for breeding, and those who use balcony flowers can set up a movable plastic shelf on it, which takes time to open and not need time to close the lid. to ensure the normal growth of orchids.

When the orchid plant is dormant, semi-dormant and just put on the pot, the fertilizer can not be absorbed; in the rainy season and high air humidity season, too much fertilizer and water will increase the heavy burden on the orchid root, and in serious cases, it can hurt the root and leaves, and even cause death. In order to ensure safety, orchids generally do not apply fertilizer during the dormant period, and it is not suitable to apply fertilizer on the roots when the plants are just put on the pot. If fertilizer is needed, 0.1% potassium dihydrogen phosphate solution can be sprayed on the leaves in the afternoon on a sunny day, once every 7 days, and 0.1% dimethoate or dichlorvos can be mixed with 0.1% dimethoate or dichlorvos to control pests.

Disinfect and disinfect orchids around the place where orchids are cultivated and potted orchids can be sprayed once every 7 days with disinfection and sterilization drugs (such as virus Chlorothalonil, Chlorothalonil, carbendazim, etc., diluted according to the instructions, used alternately). Spray with insecticide drugs (such as omethoate, dichlorvos, trichlorfon, etc., diluted according to instructions, used alternately) every 10 days. It should be noted that 2 hours after the application of insecticidal drugs, it is necessary to spray and wash the leaves of orchids with clean water to avoid drug damage.
