Embodiment

[0029] Immediately after the harvest of Panax notoginseng in that year, the land was deeply plowed to remove impurities in the land and the plant remains of Panax notoginseng, and then a dam was built around the land planted with Panax notoginseng. The height of the dam was 25-35cm, and the dam was built. Afterwards, water is released in the dam to soak the soil in the dam. The depth of water soaking is 20-30cm, and the water level is lower than the height of the dam. Keep the water level for 3-4 months. Invert rice every month, choose two crops of rice for stubble, after the two crops of rice are harvested, clean up the two crops of rice in the land, and drain the water in the two crops of rice at the same time, the soil of the land needs to be deeply plowed and exposed to the sun for 3- 15 days, and the slope of the land in the two-crop rice was trimmed to 5°-15°, avoiding waterlogging, and then planting the Radix Notoginseng seedlings, wherein the seeds of the Radix Notogins...

Abstract

The invention discloses a matching method for improving obstacles to continuous cropping of radix notoginseng. The method comprises the specific steps: 1) land deep-tillage; 2) land-surrounding cofferdam making; 3) watering soaking; 4) rice crop rotation and management; 5) drainage and land trimming; and 6) radix notoginseng seedling raising and transplanting. According to the method, the problems of use of chemical pesticides due to the obstacles to the continuous cropping of the radix notoginseng that environments are polluted, pesticide resistance is caused, and autotoxins are removed fromsoil are solved, the obstacles to the continuous cropping caused by pathogenic bacteria, nematodes, autotoxin chemical substances and the like can be effectively removed, and the method has the characteristics of low cost, environment-friendliness, simplicity, convenience and feasibility.

Description

technical field [0001] The invention relates to the field of planting Chinese herbal medicines, in particular to a matching method for improving obstacles to continuous cropping of Panax notoginseng. Background technique [0002] Panax notoginseng is one of the most commonly used bulk medicinal materials in my country. It is mainly distributed in Wenshan Prefecture, Yunnan and Baise, Guangxi. At present, Panax notoginseng is mainly cultivated artificially, and the supply of wild Panax notoginseng is very scarce. Because Panax notoginseng is a perennial plant cultivated in shade, it is suitable for a warm and humid environment, and it is highly resistant to continuous cropping. Due to the tight supply of transferable land in the planting area, continuous planting for many years has resulted in serious obstacles to the continuous cropping of Panax notoginseng. Generally, the land that has been planted with Panax notoginseng needs to be rotated for more than ten years with alfa...
