It is appropriate to choose sandy soil with loose and fertile, good drainage and humus when planting. After selecting the plot, plough it above 20cm, apply barnyard manure and compost as base fertilizer, applying 1000 kg per mu, if there is no farm manure, you can also use compound fertilizer and organic fertilizer instead, applying 100kg organic fertilizer and 50kg compound fertilizer per mu. After fertilization, mix it with the soil evenly, shallow ploughing once before planting, rake fine and level it, and make a 1.5-meter-wide high border.

2. Methods of reproduction

White and can be propagated with seeds and tubers, but sowing is more difficult, the survival rate is lower, and tuber propagation is easier, so tuber propagation is mostly used in production. Tuber propagation is generally from September to November, Bletilla striata is dug out, and medium-sized, pest-free tubers are selected. Each tuber is required to have one or two bud holes, and can be planted after mixing with plant ash. The furrow is opened according to the row spacing of 20-25cm and the ditch depth is 5-6cm. When planting, the tuber is put into the ditch according to the plant spacing of 10cm, which requires that the bud eye should be upward, the soil should be compacted and the grass should be watered.

3. Field management

After the emergence of Bletilla striata seedlings, to do a good job of weeding, Bletilla striata seedling management attaches great importance to weeding, weeds will affect the growth of seedlings, it is best to pull weeds. After weeding, it is necessary to combine the growth of seedlings and the looseness of the soil, timely ploughing and loosening the soil, whether it is intermediate ploughing or weeding, must be shallow hoe, so as not to damage the root system.

4. Fertilizer and water management

Bletilla striata is a fertilizer-loving plant, and its fertilizer and water management is related to its yield. It is generally necessary to apply fertilizer once a month, and it should not be too concentrated each time. The method of spraying or pouring fertilizer diluted with water can promote the absorption of fertilizer by root system and improve fertilizer use efficiency. After July-August, the plant stops growing and enters the dormant period, when fertilizing should be stopped, but attention should be paid to the harm of weeds and diseases and insect pests. As for water management, Bletilla striata is a shade-loving plant, so it is necessary to keep the soil moist and water in time during drought, especially from July to September, it should be watered once in the morning and evening, but at the same time it is also afraid of waterlogging, so it should pay attention to drainage in the rainy season to avoid rotting roots.
