Embodiment 1

[0036] 1. A new type of microbial multifunctional soil remediation agent, consisting of 1kg of microbial components (400g of expanded perlite per liter of bacterial liquid) and 1kg of fertilizer components (600g of perlite per liter of biogas slurry, Among them, the expanded perlite is 300g, and the perlite powder is 300g).

[0037] The microbial component is composed of expanded perlite that adsorbs complex microorganisms, and the expanded perlite is sterilized at high temperature for 30 minutes at a temperature of 110-130°C. And the effective number of viable bacteria of each microorganism in the compound microbial preparation is respectively: Bacillus Laterosporus 1 × 10 6 Individuals / mL, photosynthetic flora 1.5×10 6 Individual / mL, Bacillus subtilis 2.0×10 6 individual / mL and Bacillus licheniformis 1×10 6 pcs / mL, the expanded perlite corresponding to each liter of bacterial liquid is 400g.

[0038] The fertilizer component is made by absorbing biogas slurry with expanded...

Embodiment 2

[0061] A new type of microbial multifunctional soil remediation agent, consisting of 1kg of microbial components (450g of expanded perlite per liter of bacterial liquid) and 2kg of fertilizer components (630g of perlite per liter of biogas slurry, of which expanded pearl Rock is 280g, perlite powder is 350g).

Abstract

The invention relates to a microbial multifunctional soil improver and a preparation method thereof. The microbial multifunctional soil improver comprises the components of microbes, a biogas slurry,expanded perlite (or ceramsite with pores in the surface) and perlite powder. An organic fertilizer is combined with a microbial improver and the expand perlite (or the ceramsite with the pores in thesurface) is used as a microbial carrier so as to improve the soil environment, provide protection for the microbes, achieve resource utilization of the biogas slurry and the like. Through a synergistic effect of various microbes, the purposes of promoting the growth of plant roots, enhancing the absorption capacity of the roots, inhibiting the propagation of pathogenic bacteria inside and outsideplants, reducing pests and diseases, reducing pesticide residues, inhibiting the growth and the propagation of the pathogenic bacteria, increasing organic matters in soil, and remedying organic matter and inorganic matter contaminated soil and the like are achieved. The novel microbial multifunctional soil improver can remedy the contaminated soil, improve a poor soil condition and increase the soil fertility, and has a very great research value and a very great application potential.

Description

technical field [0001] The invention relates to the technical field of soil improvement, in particular to a microbial multifunctional soil improver and a preparation method thereof. Background technique [0002] Soil is composed of minerals formed by rock weathering, animals and plants, organic matter produced by the decomposition of microbial residues, soil organisms, water, air, and oxidized humus. Over the years, in the cultivation of crops, the amount of chemical fertilizers has been increasing, and the amount of organic fertilizers has been decreasing. However, the utilization rate of chemical fertilizers by crops is only about 30%, and about 70% of chemical fertilizers are deposited and fixed in the soil. Or with the rainwater lost in the rivers and not absorbed and utilized by crops, resulting in soil compaction, environmental pollution, eutrophication of rivers and groundwater is becoming more and more serious, the content of organic matter in the soil is reduced, th...
