Preparation method of regenerated fertilizer for restoring soil, and soil restoration method

Abstract

The invention belongs to the technical fields of agricultural soil reconstruction, fertilizer production and the biology, and concretely relates to a p reparation method of regenerated fertilizer for restoring soil, and a soil restoration method. The preparation method comprises the following steps: collecting deposits not polluted by human activities and containing abundant beneficial microbial strains in the virgin forest, used as soil seeds, adding an organic composite fertilizer, an inorganic fertilizer and an EM microbial preparation to the collected soil seeds, uniformly mixing all above materials, putting the obtained mixture in a nutrition pool, and carrying out fermenting multiplication to obtain microbial soil derivation fertilizer seeds; sampling and extracting soil through a geographic coordinate position range, measuring the content of soil to be restored, preparing the regenerated fertilizer for restoring soil, according with restored soil fertility and crop growth, and producing the fertilizer according to a measured soil formula; and applying the produced regenerated fertilizer for restoring soil to the soil to be restored. Beneficial microbes in the soil are massively bred to enhance the fertility of the soil and improve the looseness of the soil.

Description

technical field [0001] The invention belongs to the fields of transformation of agricultural soil, fertilizer production and biotechnology, and in particular relates to a preparation method of soil restoration regeneration fertilizer and a soil restoration method. Background technique [0002] With the application of more and more inorganic chemical fertilizers, the beneficial microorganisms in the soil are constantly being killed. Due to the long-term uncontrolled application of inorganic chemical fertilizers, the porosity and oxygen absorption capacity of the soil are getting worse and worse. Thin, even hardened, and the long-term application of inorganic fertilizers to crops, the taste will also become poor due to changes in organic matter content, and the fertility of the soil will degrade. As time goes by, the degree of green environmental protection and soil fertility will also increase. degraded, which is not conducive to the sustainable development of green agricultu...

Problems solved by technology

[0002] With the application of more and more inorganic chemical fertilizers, the beneficial microorganisms in the soil are constantly being killed. Due to the long-term uncontrolled application of inorganic chemical fertilizers, the porosity and oxygen absorption capacity of the soil are getting worse and worse. Thin, even hardened, and the long-term application of inorganic fertilizers to crops, the taste will also become poor due to changes in organic matter content, and the fertility of the soil will degrade. As time goes by, the degree of green environmental protection and soil fertility will also increase. degradation, which is not conducive to the sustainable development of green agriculture

[0003] At present, there are microbial compound fertilizers and biological fertilizers produced by EM microbial preparation technology in the domestic chemical fertilizer market. The disadvantage is that the content of the fertilizer and the ratio of trace elements are fixed, and it cannot be cultivated according to the soil in different regions and different crops. The realization of precise fertilization and soil testing and formula fertilization cannot solve the problem of effective restoration of soil fertility decline, soil compaction, and soil thinning due to disorderly application of inorganic fertilizers and environmental pollution.
