Detailed Explanation of the Key Cultivation Techniques for the Chinese Medicinal Herb Bletilla Striata

The cultivation of Chinese medicinal herbs has always been quite popular, and Bletilla striata is a planting project with relatively good economic benefits. However, during the cultivation process, if you are not careful, there will be reduced yield and poor benefits, which gives growers a great headache. Let us take a look together below at the key cultivation techniques for the Chinese medicinal herb Bletilla striata, to help more growers understand this knowledge.

1. Planting time for the Chinese medicinal herb Bletilla striata

It is understood that Bletilla striata is a medicinal herb that likes moist soil and a humid climate, dislikes light, and dislikes waterlogging, so we generally choose to plant Bletilla striata in autumn. Compared with spring, autumn has more suitable conditions for planting Bletilla striata. If planted at this time, by the time spring arrives it can enter a period of rapid growth, and all conditions are favorable for the growth of Bletilla striata.

When choosing seeds, everyone must pay attention: the quality of the seeds is one of the key factors related to a high yield of Bletilla striata, so varieties that are healthy, highly disease-resistant, and highly adaptable must be selected. However, sowing seeds is relatively difficult, so we generally choose the method of tuber propagation. When selecting, the same points apply: choose ones that do not carry diseases.

2. Key cultivation techniques for the Chinese medicinal herb Bletilla striata

1. Choose suitable planting soil

Generally speaking, the soil for planting Bletilla striata is required to be relatively fertile, well loosened, and rich in humus, so we generally choose hillsides with good drainage for planting. Before planting, the land should be prepared and the soil turned, organic fertilizer should be applied, and it should be evenly mixed with the soil.

2. Daily management

Weeding: during the planting period of Bletilla striata, weeds are very likely to grow in abundance, so weeding must be done on time throughout the entire growth period, especially during the vigorous growth period, when weeds also grow very quickly. In order to prevent them from competing with Bletilla striata for nutrients, herbicides can be sprayed appropriately.

Proper topdressing: base fertilizer can no longer meet the growth needs of Bletilla striata, so topdressing should be carried out during the vigorous growth period. Generally, spraying human or animal manure once a month is sufficient.

Watering: during its growth period, Bletilla striata likes moist soil and a cool climate, so during relatively dry summers, watering should be done in the morning and evening to avoid drying out. Of course, if there is a rainy season with relatively high rainfall, accumulated water should be drained in time to avoid root rot.

If Bletilla striata is planted in southern regions, root rot is very likely to occur during the rainy season. Be sure to dig drainage ditches to prevent waterlogging from damaging the roots.

3. Preventing and controlling pests and diseases

Common pests and diseases during the growth period of Bletilla striata include wireworms and cutworms. We can capture and kill them manually or treat them with professional pesticides.

4. Details of harvesting and processing

Bletilla striata can generally be harvested and processed after two or three years. The harvest time is when the aboveground stems of Bletilla striata begin to wither. After digging out the tubers and removing the soil, they can be processed. During processing, impurities should be removed, and then the skin and fibrous roots should be removed.
