Abstract

The invention discloses an efficient remediation compound microbial agent for cultivated soil. The efficient remediation compound microbial agent is prepared from a bacteria solution prepared by fermenting a compound microbial agent, and a compound adsorption carrier, wherein the mass ratio of the bacteria solution to the compound adsorption carrier is (0.01 to 0.2) to (1 to 2); the viable count is 22 to 86 million per gram; the microbial agent is prepared from bacillus megatherium, bacillus cereus, stenotrophomonas maltophilia and pseudomonas putida; the compound adsorption carrier is prepared from crop straw, active carbon and diatomite. Bacteria solutions of the bacillus megatherium, the bacillus cereus and the stenotrophomonas maltophilia are combined together, and the four bacteria facilitate one another, so that remediation of the soil can be finished more efficiently, pollution on soil suffering from heavy metal pollution and organic chemical product pollution can be eliminated rapidly, soil productivity is improved, and the remediation efficiency is increased. By adopting the compound adsorption carrier, the limit of a single carrier is overcome, the service life of a strain is prolonged, and the service cycle of the strain is prolonged.

Description

technical field [0001] The invention relates to the field of soil microbial technical restoration, in particular to a compound microbial bacterial agent for efficient restoration of cultivated soil, a preparation method and an application. Background technique [0002] Modern agriculture uses a large amount of industrial chemical fertilizers, which leads to the decline of cultivated soil fertility, serious agglomeration, and crop yield decline. This phenomenon is called "sanitary land phenomenon" in Japan, and "replanting disease" in the United States, Britain, and Canada. It is called "repeat problem". [0003] Moreover, with the increasing industrial pollution, water pollution, and air pollution, the agricultural soil has also suffered from different levels of chemical organic pollution (such as organic pesticide residues, petroleum pollution, etc.) and heavy metal pollution while the soil fertility has declined. . As for heavy metal pollution, according to the survey of...
