1、 Breeding environment

1. Soil: select the soil with good drainage and rich organic matter, which can be mixed with humus soil and sandy soil. Be careful not to choose viscous soil. When planting, lay a layer of fine sand on the bottom of the basin and expose a little root

2. Moisture: do not water too frequently, and the substrate is dry; If you feel that the soil is no longer wet, water it. The basin bottom cannot accumulate water, otherwise it will lead to bulb rot. If the soil is dry and cracked, water it in time, otherwise the stem and leaf will grow too fast and affect the flowering

3. Light: orchid is a plant that likes sunshine. During plant growth, it can be placed in a sunny, ventilated and dry place, but be careful not to place it in direct sunlight

4. Temperature: when flowering in spring, the suitable temperature for growth is 18-23 ℃; When dormant in winter, keep it at 5-10 ℃

5. Fertilization: during the growth period, cake fertilizer is selected and fertilized once every half a month. Continue to apply fertilizer after the flowering period is stopped, mainly phosphorus and potassium fertilizer, reduce the amount of nitrogen fertilizer, and stop applying fertilizer at the end of autumn

2、 Breeding method

1. Split plant: cultivate the small bulbs on the head in blocks. After 1-2 years, many small bulbs will grow on the head, and then change pots, soil and split plant culture can be carried out

2. Ball distribution: from February to march in spring, take out the ball collected last year, peel off the small ball around the mother ball, and dry it for two days. Water once just after planting in the pot, and then water after flowering

3、 Pest control

1. Virus disease: use 75% chlorothalonil wettable powder 700 times liquid to spray the leaves

2. Spot disease: autumn is the peak of the disease. The diseased leaves should be removed after the disease, or the bulbs should be soaked in 0.5% formalin solution for about 2 hours before planting

3. Nematode disease: soak the bulb in 43 ℃ warm water with 0.5% formalin for 3-4 hours
