Cultivation method for overcoming continuous cropping obstacle of rhizoma corydalis

Abstract

The invention provides a cultivation method for overcoming the continuous cropping obstacle of rhizoma corydalis. The method includes the steps of land selection, soil preparation, planting, fertilization, field management, harvesting and subsequent preservation. Before sowing, selected rhizoma corydalis tubers are soaked in 500 times liquid of 50% carbendazim wettable powder for 1 hour, and the survival rate and germination rate of seeds can be improved significantly. In the fertilization process, a microbial fertilizer, an organic fertilizer and a trace element fertilizer are additionally applied in the field management process, by reducing the release of allelochemicals at the roots of the rhizoma corydalis, the soil environment of the root of the rhizoma corydalis is regulated, high-temperature stress and lesions in the growth process of rhizoma corydalis are effectively prevented, the use of pesticide is reduced, the continuous cropping obstacle is prevented, the safety of rhizoma corydalis is ensured, and the quality and yield of rhizoma corydalis are improved.

Description

technical field [0001] The invention relates to the planting of Chinese medicinal materials, in particular to a cultivation method for overcoming obstacles in continuous cropping of Corydalis Corydalis. Background technique [0002] Corydalis Corydalis Corydalis Corydalis Corydalis yanhusuo W. T. Wang's dried tubers, which were first recorded in "Supplements to Materia Medica", are one of the famous "Eight Flavors of Zhejiang" and commonly used bulk medicinal materials. Corydalis Corydalis has a long history of medicinal use, a short cultivation period, and a wide range of production areas. It is mainly produced in Pan'an, Zhejiang, and Hanzhong, Shaanxi. Chongqing Kaixian was successfully introduced and cultivated from Zhejiang in 1972. It has a long history of cultivation and has the advantages of "solid texture, full granules, and high quality". It is one of the main export Chinese medicinal materials in the Three Gorges reservoir area. Studies have found that benzyliso...

Problems solved by technology

At present, in the artificial cultivation and domestication of Corydalis, there are generally serious problems such as unclear provenance, degeneration of varieties, high incidence of diseases and insect pests, and the use of traditional cultivation models, resulting in reduced yield and quality of Corydalis, resulting in obstacles to continuous cropping, which greatly limits the artificial cultivation of Corydalis. sustainable development

[0003] There is such a phenomenon in the cultivation process of Corydalis Corydalis, that is, farmers have planted Corydalis Corydalis in the same land for many years, which continuously releases allelochemicals into the soil, and the soil microenvironment loses balance, resulting in changes in microbial communities, resulting in the yield and quality of Corydalis Corydalis have declined sharply, and pests and diseases have intensified. This phenomenon is called continuous cropping barrier
