Problems solved by technology

[0006] (1) The preparation process is lengthy and complicated, and there are many steps in the process, which takes a certain amount of time
Both strain propagation and fermentation composting have time limits
[0007] (2) In an acidic environment, or after a certain period of time, the biological activity of the passivated heavy metals will increase again, and the heavy metals in the carbonate-bound state may be re-released into the soil environment as the pH changes. The passivation agent cannot Fundamentally solve the problem of heavy metal polluted soil, which may even affect the availability of bio-organic fertilizers

Abstract

The invention discloses a method for preparing a bio-organic fertilizer by taking pre-meal garbage as a raw material. The method comprises the following steps: S1, preparing a fermentation compost composite microbial agent, wherein the composite microbial agent comprises bacillus subtilis, trichoderma viride, azotobacter chroococcum, monas aeruginosa, bacillus amyloliquefaciens, aspergillus oryzae and saccharomycetes; s2, performing aerobic fermentation treatment on the pre-meal garbage; s3, secondary composting and maturing treatment; s4, preparing a passivating agent substance: uniformly mixing 6 parts of biochar and 4 parts of sepiolite; s5, uniformly mixing the substances prepared in S3 and S4 to obtain a first mixed substance, uniformly mixing the first mixed substance and soil according to a ratio of 5: 1, and standing and balancing for 3-7 days in a ventilated place to obtain a second mixed substance; s6, establishing an AMF-plant combined symbiotic system: preparing AMF strain activation and propagation culture, adding the propagated AMF into the second mixture prepared in S5, and uniformly stirring to prepare the biological organic fertilizer.

Description

technical field [0001] The invention belongs to the technical field of agricultural application, and in particular relates to a method for preparing bio-organic fertilizer by using pre-dinner garbage as raw materials. Background technique [0002] In recent years, with the development of science, technology, economy and industrialization in China, the discharge of various heavy metals in the environment has continued to remain at a relatively high level. In addition, my country has a vast territory and rich metal mineral resources. Studies have shown that the land area polluted by heavy metals in my country can Reaching 1.4 million hectares, of which farmland accounts for about 1 / 4. Therefore, the problem of heavy metal soil pollution in farmland is currently serious in my country. Among them, heavy metal element cadmium (Cadmium, Cd) pollution has become an increasingly serious and difficult environmental problem, which has attracted the attention of many scholars around the...
