Method for removing continuous-cropping obstacles of facility cultivation soil

Abstract

The invention belongs to the field of soil improvement, and discloses a method for removing the continuous-cropping obstacles of facility cultivation soil. The method comprises the following steps: selecting a time period with the highest air temperature and the strongest sunlight in summer, preparing 1-1.5 t of an organic fertilizer, 100-150 kg of lime-nitrogen granules, 10-25 kg of plant ash, 30-50 kg of a soil bactericide solution mixed with water of 500-800 times, and 1-1.5 kg of a microbial preparation per mu; spreading the mixed fertilizer subjected to uniform mixing on the soil surface;carrying out deep tillage and building beds, carrying out film coverage, water irrigation and sealing, and controlling the temperature, wherein the temperature of a soil layer with a depth of 20-40 cm is 40-50 DEG C on a sunny day; controlling the temperature of the soil surface to be larger than or equal to 70 DEG C; controlling the temperature and carrying out disinfection for 20-30 days; and removing films. Through the method provided by the invention, the fertility of the soil can be increased, simultaneously sterilization is carried out by utilizing acidity and alkalinity, the bactericide is further utilized to eliminate the soil diseases and insect pests caused by repeated planting of a same crop, and the yield of continuous-cropping plants of the soil is increased.

Description

technical field [0001] The invention belongs to the field of soil improvement, and in particular relates to a method for removing obstacles in protected cultivation soil continuous cropping. Background technique [0002] At present, the existing technologies commonly used in the industry are as follows: [0003] In recent years, with the adjustment of the agricultural industry structure, modern agriculture based on facility cultivation (greenhouses, solar greenhouses) has developed rapidly, which has played a demonstration and guiding role in promoting agricultural efficiency and increasing farmers' income. However, protected cultivation land is a special ecological environment. With successive years of planting, the growth of vegetables is getting worse and worse, and there are more and more diseases, especially the physiological diseases of vegetables are getting worse year by year, and the yield and economic benefits are showing a downward trend. This is because under t...

AI Technical Summary

Problems solved by technology

[0011] It cannot solve the problem that the soil cannot be washed by rainwater and direct sunlight for a long time, and the situation of soil obstacles caused by self-poisoning caused by continuous cropping of vegetables cannot be alleviated, and the threat to production and development cannot be effectively curbed.

[0012] The existing technology cannot combine microbial strain preparations to improve soil continuous cropping obstacles, promote the proliferation of beneficial bacteria, and prevent and control crop diseases and insect pests
