1. Cultivate strong seedlings
Crab claw orchid generally adopts cutting propagation, which is usually carried out from March to April in spring or from September to the beginning of 10 in autumn. Cut off 5-7 strong stems and leaves, insert them into loose and breathable semi-sandy soil matrix, and use nutrient bags, paper cups, grass pots, seedling trays and other seedling containers for cutting seedlings, or use foam plugs for floating cutting seedlings, or directly cut them into flowerpots, and then transplant seedlings first.
Crab claw orchid, mostly garden soil or pond mud, humus soil, peat soil and so on. , is mixed with the same amount of river sand or cinder, chaff ash, chaff charcoal, rotten sawdust, edible fungi leftovers, etc. And they are all used as cutting substrates. The cutting depth is 1.5. Keep it in a bright and ventilated place without direct sunlight for maintenance. Water in time, keep the cutting substrate moist, and it is better to dry the cutting substrate too much or wet it for a short time. Generally, after cutting 1 month, it is moved to a semi-shady and semi-sunny place for maintenance. It can be transplanted into the pot in time after 2 months.
Step 2 transplant into a flowerpot
Crab claw orchids can be transplanted at any time all year round as long as the appropriate temperature is maintained, and it is better to transplant before germination in spring and September-65438+10 in autumn. Choose a pot of suitable size, and apply some soaked animal bones or hoof horns on the bottom of the pot as base fertilizer. With the growth of plants, you can gradually switch to a slightly larger pot for planting.
Crab claw orchid, a slightly acidic sandy soil with loose and fertile soil, rich humus and good drainage and air permeability, can be used in 2 parts of loose and fertile pastoral soil and pond mud, 2 parts of decomposed urban garbage soil, humus soil, peat soil, pine needle soil, 2 parts of river sand or cinder, 2 parts of decomposed high-quality farm manure or cake fertilizer crumbs, and decomposed sawdust, coconut bran, tree bark crumbs and chaff.
Step 3 protect the environment
Crab claw orchids should be kept in sunny places during the growing season; Shading should be appropriate in summer and autumn to block about 50% ~ 60% of the sun; In winter, it is advisable to move indoors for wintering, and the room temperature should be kept above 10℃. Attention should be paid to the ventilation and light transmission of the environment at ordinary times, and it should not be affected with damp in rainy season; When it is in full bloom, it can be moved indoors for viewing.
4. Water and fertilizer management
Crab claw orchid, in the growing season, should keep the surface of the basin soil dry and moist, that is, water it once when the surface of the basin soil is slightly dry, and combine with watering, use decomposed thin chicken manure water or cake fertilizer water, 5% calcium superphosphate and 1% potassium sulfate aqueous solution, 2 ~ 4 times a month. In winter and spring, it is advisable to water or topdressing at noon on sunny days; Summer and autumn should be watered or topdressing in the morning or evening, and Ying Qin should spray water mist on the leaves at night. Combined with foliar water spraying, foliar water mist is sprayed every 1 ~ 2 weeks with 0. 1 urea aqueous solution and 0.2% potassium dihydrogen phosphate aqueous solution. Topdressing should be stopped in hot weather in Xia Dong. Water less in winter and keep the soil slightly dry.
Pruning and remodeling
Crab claw orchids, which are usually not pruned much, should be pruned once after flowering. Plants that have been cultivated for many years can be supported by iron ring columns layer by layer, and then long stems and leaves and dense branches and leaves can be cut short. Crab claw orchid and cactus can also be used as rootstocks for layered grafting and maintenance, which can improve the ornamental effect and economic value.
6. Turn over the pots and change the soil
Crab claw orchid should be turned once a year or every 1 ~ 2 years, often before germination in spring. Three quarters of the old soil should be replaced, the roots that are too long should be cut short, fully fertilized, and the newly prepared culture soil should be used to replant the pots. Can be combined with turning pots and changing soil for ramet propagation. (Some pictures are from online friends)
To sum up, when maintaining the crab claw orchid, we should pay attention to the ventilation and light transmission of the maintenance environment; Rain protection in rainy season; In summer and autumn, it is necessary to shade moderately to avoid exposure to the hot sun; Stop fertilizer and lack water in winter. Avoid applying raw fertilizer and thick fertilizer; In summer and autumn, topdressing should be carried out in the evening and watered again the next morning. Pay attention to the prevention and control of stem rot, sooty blotch and stem blight.
