Problems solved by technology

[0004] In continuous cropping soil, due to the cultivation of the same crop year after year, a large number of harmful microbial populations are bred in the soil, while the activities of beneficial microorganisms such as nitrifying bacteria and ammonifying bacteria in the soil are inhibited, so that the microbial flora of the soil occurs As a result, the proportion of microorganisms in the soil is unbalanced, and the applied fertilizer cannot be effectively decomposed, resulting in uneven distribution of soil nutrients and exacerbating the spread of soil-borne diseases.
[0005] At present, there are various methods to relieve continuous cropping obstacles, including physical methods and chemical methods, such as application of microbial agents, high-temperature sterilization, increasing application of organic fertilizers, rational irrigation, grafting and root replacement, guest-soil methods, etc., but only rely on some simple methods It is impossible to prevent and control continuous cropping obstacles, and it is necessary to carry out targeted prevention and treatment according to the causes of continuous cropping obstacles in production

Abstract

The invention discloses a soil micro-ecological environment restoration method for eliminating a continuous cropping obstacle. The soil micro-ecological environment restoration method for eliminating the continuous cropping obstacle is realized by combining a soil reducing microbial inoculum and a technology of closing a greenhouse at a high temperature after irrigation. Compared with the prior art, the soil micro-ecological environment restoration method for eliminating the continuous cropping obstacle, disclosed by the invention, has the good characteristics of being environment-friendly, sustainable, easy to operate, and convenient to popularize.

Description

technical field [0001] The invention relates to the technical field of soil restoration, in particular to a soil micro-ecological environment restoration method for eliminating continuous cropping obstacles. Background technique [0002] Continuous cropping obstacle refers to the continuous planting of the same or similar plant in the same field, which makes the plant grow slowly, and even the occurrence of diseases leads to a decrease in yield. Japan calls it "the bogey ground phenomenon", and Europe and the United States call it disease replanting or replanting problem. The main causes of continuous cropping obstacles are divided into five categories: first, the lack of soil nutrients; second, the abnormal response of the soil; third, the continuous deterioration of soil physical and chemical properties; Changes in the content of soil microflora. [0003] The continuous planting of a single crop forms a special soil environment. The beneficial microorganisms in the soil ...
