Problems solved by technology

[0005] The Chinese invention patent of CN 102391876 B discloses a compound biological soil improver and its application. The method uses Trichoderma pseudoconii fermentation broth, Bacillus subtilis fermentation broth, water-soluble chitin, potassium fulvic acid and decomposed organic matter The soil improver prepared by compounding has the advantages of simple production method and pollution-free product, but it only contains two kinds of microorganisms, and the improvement effect on the soil microbial community is not obvious. The soil improver does not contain substances that improve the physical properties of soil. And it cannot adjust the soil pH value, so its improvement effect on soil is limited, not worth promoting

Abstract

The invention discloses a composite biological soil conditioner and a preparation method of the composite biological soil conditioner. The composite biological soil conditioner comprises the following steps: 1) preparing charcoal; 2) modifying the charcoal; 3) fermenting livestock excrement; 4) preparing an ecological organic fertilizer; 5) compounding, wherein the soil conditioner comprises the following materials in parts by weight: 130-150 parts of modified charcoal, 250-280 parts of the ecological organic fertilizer, 30-35 parts of humic acid, 5-8 parts of probiotics, 3-5 parts of active peptide, 32-38 parts of a water retaining agent, and 190-220 parts of an auxiliary. The composite biological soil conditioner has the beneficial effects that the soil conditioner not only strengthens the water holding capacity of soil, but also improves the soil structure, reduces the bulk density of the soil, increases the porosity and the content of organic matters in the soil, regulates the pH value of the soil, improves the microbial flora of the soil, inhibits the growth and propagation of pathogenic bacteria of a root system, and complexes and adsorbs the heavy metal ions in the soil, and therefore, the composite biological soil conditioner is a safe and efficient composite biological soil conditioner.

Description

technical field [0001] The invention relates to the field of soil improvers, in particular to a composite biological soil improver and a preparation method thereof. technical background [0002] Soil refers to a layer of loose material on the surface of the earth, which is composed of minerals, animals and plants, solid-phase substances, liquid-phase substances, gas-phase substances, oxidized humus, etc. formed by rock weathering. Solid substances include soil minerals, animals and plants , organic matter and nutrients obtained by microorganisms through photoinhibition and sterilization, organic matter produced by the decomposition of microbial residues, etc.; liquid matter mainly refers to soil moisture; gas is air existing in soil pores, and these three types of substances in soil constitute They form a contradictory unity, they are interrelated and restrict each other, provide the necessary living conditions for crops, and are the material basis of soil fertility. Soil i...
