Let's take a look at how many seedlings Bletilla striata needs per mu.

How many seedlings does Bletilla striata need per mu?

Bletilla striata needs about 8000 to 10000 seedlings per mu. The authentic Bletilla striata has only one kind of purple flower Bletilla striata, and there are two ecotypes, one is a large type in Hubei and Jiangsu, and the other is a small type in Yunnan, Guizhou and Sichuan, in which the yield of large type is high. therefore, it is better to choose large type and 1 ~ 2-year-old tubers with fibrous roots. although there are tissue culture seedlings for sale at present, the tissue culture seedlings are lack of mycorrhizal fungi, and the survival rate of poor resistance is low after transplanting to the field.

How much does Bletilla striata cost per mu?

The planting cost of Bletilla striata per mu varies with different seedling selections. generally, if tuber is used, the domesticated seedling is about 15000 yuan, the bottle seedling is about 8000 yuan, and the fertilizer cost per mu is about 200 yuan. The annual management and expenses are about 2000 yuan, so the cost per mu of Bletilla striata is about 10000mu.

How much Bletilla striata can be harvested per mu of land?

If the cultivation of Bletilla striata is well managed, it can be harvested in 2 years, but the yield in 3 years will be higher. Generally, the dry goods in high-yield fields can reach about 500 jin in 3 years, 300 jin in middle-yield fields and 250 jin in low-yield fields. At present, the price of dry goods is about 150-250 yuan per jin. Its market price is related to quality, divided into top, middle and lower, the better the quality, the higher the price.

What are the risks of planting Bletilla striata?

1. Production overheating: in addition to the traditional Yunguichuan, Bletilla striata production has been artificially planted in Shaanxi, Henan, Fujian and Guangxi in the north, Jiangsu and Zhejiang in the east and Gansu in the west. therefore, overheating production is bound to form a certain risk to the cultivation of Bletilla striata.

2. The cost is high: compared with other planting projects, the investment cost of Bletilla striata planting is much higher, and the growth period is 2 to 3 years. This kind of investment cost and production cycle can not be borne by ordinary farmers at all, and it also increases the investment risk.

3. Variety confusion: the provenance confusion of Bletilla striata is famous in traditional Chinese medicine. At present, purple Trigeminal Bletilla striata is in circulation in the chemical industry, while the Pharmacopoeia mainly uses Purple Trigeminal Bletilla striata. Other yellow flowers, White Bletilla striata and so on are idioms and counterfeits.

4. Seed and seedling sources: the most common seedling cultivation methods of Bletilla striata are seed direct seeding, tuber propagation and tissue culture seedlings, of which the most reasonable and economical is seed direct seeding, which has high survival rate and high yield, but the cost is too high. the tissue culture seedling has the lowest survival rate.

5. Technical risk: the seedlings of Bletilla striata are usually transplanted after the introduction of provenances, tissue culture, refining seedlings and roots, but because the growth of the rhizome requires a symbiotic environment and very fine transplanting and management, the seedling death rate can usually reach 50% or more.
