High-quality and high-yield cultivation method of coptis chinensis

Abstract

The invention relates to a high-quality and high-yield cultivation method of coptis chinensis and solves the problem that coptis chinensis is low in yield. According to the technical scheme, the method includes: bagging or isolation seed reproduction is used, typical large floral leaves are selected as seed reproduction female parents, typical large floral leaf seedlings are selected from a nursery garden, isolation cultivation is performed, a female parent field is built, impurities and inferiors are removed during female parent field management, sparse planting of 20000 plants per mu is performed, seed reproduction is performed timely, the seeds planted for four years are highest in budding rate, budding potential and emergence rate, the winter fertilizer of the female parent field is prepared from late September to early October, 2kg of microorganism active bacterium fertilizer, 5kg of available phosphorus and 3kg of available potassium are applied to 50kg of mu rapeseed cake and covered with soil to 1-1.5cm, seed strengthening fertilizer is applied before early spring bolting accordingly to the quantity that 10kg of ammonium bicarbonate and 10kg of potassium sulfate are added to 10kg of ammonium dihydrogen phosphate and covered with earth to 0.5-1.0cm, seeding is performed in late September, and every 5kg of coptis chinensis seeds are soaked by zeatin with the concentration of 10ppm for 30 minutes, the water is then filtered, and the seeds are aired.

Description

technical field [0001] The invention belongs to a method for planting Coptis chinensis, and relates to a high-quality and high-yield cultivation method for Coptis chinensis. Background technique [0002] Coptidis is a commonly used and valuable traditional Chinese medicine. Famous and valuable lies in the strict requirements on the planting ecological environment, it is difficult to expand the scale of production without limit. Coptis chinensis is not only bitter in nature and taste, but also has many planting procedures and high labor intensity. Regardless of seedling cultivation, management, harvesting, and processing, everything that comes into contact with Coptis chinensis branches, leaves, roots, and dust is bitter. Since the founding of the People’s Republic of China, Professor Xu Jingtang transferred Coptis chinensis to home cultivation (Chinese Academy of Medical Sciences, in the 1950s), researcher Zeng Qingmei’s research on the basic technology of Coptis chinensis ...
