Embodiment 1

[0023] A planting method for overcoming obstacles in continuous cropping of Corydalis, comprising the following steps:

[0024] (1) Site selection, choose sandy soil with an altitude of 400 meters as the planting area, and the lighting is good. For seed selection, Corydalis tubers collected in Guzhu Village, Xinwo Town, Pan'an County, Zhejiang Province were selected as the provenance. Plant in the same field for two years as a control, plant according to the conventional method in the first year, and plant according to this method in the second year.

[0025] (2) Soil preparation: sort out the weeds in the planting area 2 months before planting, turn over the soil and make the soil fine, and make furrows and furrows. The width of the furrow is 130 cm, the width of the furrow is 25 cm, and the depth of the furrow is 20 cm. .

[0026] (3) Planting. Sowing is carried out in October every year. Before sowing, the selected seed tubers are soaked in 50% carbendazim wettable powder...

Embodiment 2

[0036] A planting method for overcoming obstacles in continuous cropping of Corydalis, comprising the following steps:

[0037] (1) Site selection, choose sandy soil with an altitude of 500 meters as the planting area, and the lighting is good. For seed selection, Corydalis tubers collected in Xiaokengmen, Shanghu Town, Pan'an County, Zhejiang Province were selected as the provenance. Plant in the same field for two years as a control, plant according to the conventional method in the first year, and plant according to this method in the second year.

[0038] (2) Soil preparation: sort out the weeds in the planting area 3 months before planting, turn over the soil and make the soil fine, and make furrows and furrows. The width of the furrow is 150 cm, the width of the furrow is 30 cm, and the depth of the furrow is 25 cm. .

[0039] (3) Planting. Sowing is carried out in October every year. Before sowing, the selected seed tubers are soaked in 50% carbendazim wettable powder...

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...
