Problems solved by technology

[0010] 1. It is impossible to fundamentally reduce the amount of bacteria in the soil. The diseased fields are still not suitable for planting cruciferous plants, and the amount of available soil has not been improved. spread by water;
[0011] 2. The time period is long, which has a great impact on the yield of cruciferous crops;
[0012] 3. The cost of using chemical agents, microorganisms or planting highly disease-resistant varieties is high

Abstract

The invention relates to the technical field of clubroot prevention and control, and discloses a method for rapidly reducing clubroot harm in a farmland. The method comprises the following steps: S1,seedling field preparation is conducted, specifically, a field parcel with serious clubroot is selected, plowing is conducted after removing weeds, and a fertilizer required by soybeans is applied before sowing; S2, soybeans are planted, specifically, soybean seeds are selected, and the soybeans are uniformly sowed between May 10th and May 15th; S3, plowing and re-planting are conducted, specifically, after 35-55 days, the grown soybean plants are smashed, plowing is conducted, and the soybeans are uniformly sowed again; and S4, harvesting is conducted timely, specifically, the soybeans are harvested between September 10th and September 15th. According to the method, the soybeans are continuously planted twice, and the respective planting time, growth time and treatment modes of the soybeans in two seasons are limited, so that the bacterial source amount of soil is reduced, the available soil quantity is rapidly increased, clubroot dormant spore propagation is prevented, and meanwhile,the effects that the yield of cruciferous crops such as oilseed rape is not influenced, and the cost is low are achieved.

Description

technical field [0001] The invention relates to the technical field of clubroot prevention and control, in particular to a method for quickly reducing the harm of clubroot in farmland. Background technique [0002] Rapeseed, together with soybeans, peanuts, and sesame, is listed as the four major oil crops in my country. It is not only the main raw material for edible oil, but also an important industrial raw material and an important biological resource for future renewable energy. The oil content of rapeseed is more than 33%, which provides high-quality edible oil necessary for people's life. Rapeseed oil with high erucic acid content can also be used as lubricating oil for mechanical processing and textile industry. The cake residue after oil extraction from rapeseed contains 36% crude protein, which has high nutritional value and is an excellent feed for livestock and poultry. In addition, rapeseed can also be planted on newly cleared land, fallow land and saline-alkali...
