Seed planting techniques of Bletilla striata

Planting Bletilla striata seeds requires land preparation, which is more suitable in a warm environment. Then fill the soil with base fertilizer to arrange sowing, and it is more convenient for tuber propagation. After emergence, field management can be carried out, weeding, ploughing and loosening soil, watering and fertilization are essential links.

Seed planting techniques of Bletilla striata

1. Land selection and preparation

Bletilla striata has strong adaptability and has no special requirements for soil. It likes warm and moist environment and is not cold-resistant. 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.
