Rhizome bletilla high-yield cultivation method

Abstract

The invention discloses a rhizome bletilla high-yield cultivation method which provides technical support for manual development and utilization of rare endangered medicinal plant rhizome bletilla and wild resource effective protection. Fertile sandy soil is selected as cultivation field for the rhizome bletilla, and a privious crop is crops of grass family or solanaceae. Base fertilizer is added in the process of soil preparation. Health seedballs of annual growth or biennial growth are selected, each seedball is 5-10g in weight, suitable seeding time is December to Match in the next year, and the seedballs are sowed in lines with distance 10cm*15cm. In the process of field management, intertillage and weeding are carried out for 3-5 times from Match to May each year. The seedballs are kept out of the sun from June to August by shielding or being accompanied by weeds. The rhizome bletilla cultivation field can not accumulate water. Straw ash soil should be broadcasted with the intertillage or urea, superhosphate and potassium sulphate are dressed each year. The rhizome bletilla can be harvested after 3-year cultivation.

Description

technical field [0001] The invention relates to the field of agricultural science and technology, in particular to a high-yield cultivation method for the rare and valuable medicinal material radix chinensis. Background technique [0002] The rare and precious medicinal material Bai Ji is the dried tuber of the orchid plant Bai Ji. White and ( Bletilla striata ) is a small perennial herb. Due to its high economic value, the market demand is increasing year by year, and the price is rising year by year. Wild resources are destructively excavated. Wild resources are endangered. They are listed as rare and endangered plants in the country for protection, and It is also included in Appendix II of the Convention on International Trade (CITES), which is protected internationally and prohibits the trade of wild resources. In addition, Baiji has large flowers and bright colors, and has high ornamental value. Baiji tubers contain Baiji gum (phlegm), starch, volatile oil, glucose, ...

Problems solved by technology

[0003] Carrying out artificial cultivation is the most effective way to solve the market demand and protect the resources of Baiji. At present, Baiji is planted as a bulb, and the input cost is high. Because the cultivation technology is quite immature, the yield is low, the income is small or even loss, so that ent
