How much is the latest Bletilla striata per mu?

Bletilla striata is a commonly used medicine for astringent hemostasis. at present, most of them still rely on the wild, but the wild resources are limited. Years of excessive mining and the impact of natural disasters have led to a sharp decline in wild Bletilla striata production, and the contradiction between supply and demand is expanding day by day. The best way to solve the shortage of resources is artificial planting. Let's take a look at how much Bletilla striata invests per mu.

How much is the investment of Bletilla striata per mu?

1. Seedlings: about 30, 000 yuan per mu for tuber planting, 15000 yuan for domesticated seedlings, and about 8000 yuan for bottle seedlings.

2. Fertilizer: it is estimated that 200 yuan of fertilizer will be invested per mu per year, and 200 yuan per mu for 3 years.

3. Others: daily management and other expenses are about 1000 yuan per year, and about 3000 yuan per mu for 3 years.

Planting risk of Bletilla striata

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

2. Investment risk: compared with other planting projects, the investment cost of Bletilla striata planting is much higher, and the growth period is 2 to 3 years, which can not be borne by ordinary farmers at all. At the same time, it also increases the investment risk.

3. Provenance risk: 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 common articles and counterfeits.

4. 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.

Planting method of Bletilla striata

1. Soil selection: Bletilla striata should drain well sandy loam and humus loam with more humus, prefer warm and slightly humid environment, not cold-resistant, and shady slope wasteland should be selected when planting in mountainous areas with good drainage.

2. Land preparation: the Bletilla striata planting land is ploughed more than 20 centimeters, 1000 kilograms of farm manure is applied per mu, and then the soil and fertilizer are mixed evenly. Before planting, the land is fine and raked flat, making a high border with a width of 130 centimeters and 150 centimeters.

3. Intermediate ploughing and weeding: Bletilla splendens seedlings grow vigorously from May to June, and weeds grow very fast, so weeding should be carried out, weeding combined with loosening the border surface, and shallow weeding should be done to avoid root damage.

4. timely topdressing: Bletilla striata is a fertilizer-loving plant, usually sprayed with potassium dihydrogen phosphate or thin human and animal feces once a month, stop growing and enter dormancy from July to August, but to prevent weeds from growing.

5. Irrigation and drainage: Bletilla likes a shady and humid environment, so it should always be kept moist, watered in the morning and evening from July to September, but Bletilla striata is afraid of waterlogging, and it should be drained in time to avoid root damage in case of heavy rain.

6. pest control: Bletilla striata black spot disease was sprayed with 1000 times of methyl topiramate wet powder, root-knot nematode disease was irrigated with 3% carbofuran granules, and ground tiger could be artificially trapped and killed or mixed with poisonous soil.
