Soil restoration method

Abstract

The invention discloses a soil restoration method. The method adopts a unique microbial strain formula with significant effect on eliminating heavy metal ions and chemical residues, and the microbial strain formula comprises actinomycetes, yeast actinomyces, bacillus, mould, photosynthetic bacteria, rhizosphere bacteria, a variety of beneficial microorganisms and various extracellular enzymes. The flora acts on the soil together to produce a gelatinous substance ''phosphate chitosan'', which bonds various small particles in the soil together to form good granular structure, in order to facilitate natural circulation of water, fertilizer, gas and heat, and avoid hardening and desertification of the soil; at the same time, organic fertilizer is added into the soil to maintain soil moisture content, help microbial propagation and enhance soil repair strength, and a large number of nutrients taken away in the planting process can be returned to the soil. When the temperatures is above 10 DEG C, the soil heavy metal ion content can be reduced by 50%, and chemical residues can be reduced by 60% in 35 days by using the method.

Description

technical field [0001] The invention belongs to the field of soil restoration, in particular to a soil restoration method. 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. Its composition ratio is roughly: air and water each account for 25%, solids account for 45%, organic matter accounts for 3%-4%, and microorganisms account for about 1%. Once this ratio is out of balance, it is an unhealthy soil. They are interconnected and restrict each other, providing the necessary material conditions for crop growth. For the formation of soil, various soil-forming factors are equally important and mutually irreplaceable, among which microorganisms play a leading role. It can be said that soil is formed by living microbial flora acting on soil parent material under certain climate and terrain conditions; soil has "...

AI Technical Summary

Problems solved by technology

In the past 10 years, the organic matter content of cultivated land in some provinces has continued to decline by more than 20%; more than 50% of the cultivated land is deficient in trace elements, with a total of 2.36 billion mu (times) of deficient areas of boron, manganese, zinc and iron every year; the total area of ​​cultivated land 70%-80% of the soil is deficient in nutrients, 20%-30% is excessive in nutrients, and the fertilization of all arable land is unbalanced; excessive application of chemical fertilizers generally leads to soil degradation, shallow plow layer, poor tillability, and reduced water retention capacity.
