Planting method of restraining polygonatum odoratum successive cropping obstacles

Abstract

The invention discloses a planting method of restraining polygonatum odoratum successive cropping obstacles. The planting method includes the steps that after the first crop of polygonatum odoratum is harvested and before the second crop of polygonatum odoratum is planted, the aboveground parts of polygonatum odoratum are cleaned up, cogongrass is stacked and then burned, then, plowing is conducted, the depth of soil plowing is 40-60 cm, soil disinfectant, a soil repair agent, a microbial agent and base fertilizer which is specially used for successive cropping are applied to the soil, and finally, the soil is compressed and aired. The planting method of restraining the polygonatum odoratum successive cropping obstacles is conducive to improving nutrient elements of the soil for polygonatum odoratum successive cropping, the diseases and pests of polygonatum odoratum are reduced, and the yield and quality of polygonatum odoratum on the soil for successive cropping can be improved.

Description

technical field [0001] The invention relates to the technical field of cultivation of traditional Chinese medicinal materials, in particular to a planting method for suppressing continuous cropping obstacles of Polygonatum polygonatum. Background technique [0002] Polygonatum Polygonatum is a perennial herb of Liliaceae. The rhizome is horizontal, the flesh is yellowish white, densely grown with many fibrous roots, the leaves are green, the underside is gray, the flowers are axillary, usually in clusters of 1-3. It is native to Southwest China, but it is widely distributed in the wild. It is cold-resistant and shade-tolerant, and likes a humid environment. It is suitable for growing in loose soil rich in humus. The rhizome of the plant can be used for medicine. Polygonatum odoratum has the functions of nourishing yin, moistening dryness, clearing heat, promoting body fluid, and relieving cough. It is used as a nourishing medicine. It is mainly used to treat diseases such ...

Problems solved by technology

[0003] With the continuous expansion of the planting area of ​​Polygonatum odoratum and continuous cultivation throughout the year, the problem of continuous cropping obstacles in the production of Polygonatum odoratum is becoming more and more serious, which is manifested as poor growth and development of plants, aggravation of diseases, and decline in yield and quality. The methods mainly include crop rotation, breeding of disease-resistant varieties, chemical pesticide sterilization and disinfection, etc. Crop rotation is the most traditional and effective method, which increases the total amount of soil microorganisms and reduces the incidence of disease. development, crop rotation is not feasible

Breeding disease-resistant varieties has always been an important topic in the field of disease-resistant cultivation and breeding of Chinese herbal medicines. However, the resistance, high yield, and high quality of varieties have not yet reached an organic unity. The residual problem is serious
