Soil curing method for saline and alkaline land by using amino acid soil deep scarification agent

Abstract

The invention provides a soil curing method for saline and alkaline land by using an amino acid soil deep scarification agent. The soil curing method comprises a step of applying the soil deep scarification agent. The soil deep scarification agent comprises the following components in parts by weight: 18-25 parts of amino acids, 3-5 parts of soil saccharomycete powder, 4-8 parts of a bacillus laterosporus bacteral solution, 10-15 parts of peanut bran, 7-8 parts of shrimp and crab shell powder, 6-7 parts of urea formaldehyde resin, 2-3.5 parts of hydrolyzed polyacrylonitrile, 5-9 parts of citric acid, 1-2 parts of carboxymethylcellulose, 3-4 parts of pyroligneous liquor, 7-12 parts of poly-cis-butenedioic acid and 4-6 parts of calcium sulfate. By using the soil curing method provided by the invention, once the soil is cured after five months, the microbial content is improved by 3.5-4 times, the increased quantity of earthworms is 5-7 / m2, and the average size of the granular structure is 3.5-4.3 mm.

Description

technical field [0001] The invention belongs to the technical field of saline-alkali soil curing, and relates to an amino acid soil subsoiling agent, in particular to a method for saline-alkali soil maturation using the amino acid soil subsoiling agent. Background technique [0002] In the process of utilization of saline-alkali land, simply put, it can be divided into light saline-alkali land, moderate saline-alkali land and heavy saline-alkali land. Light saline-alkali land means that its emergence rate is 70%-80%, and its salt content is less than 3 per thousand; heavy saline-alkaline land means that its salt content exceeds 6 per thousand, and its emergence rate is less than 50%; The block is a moderately saline-alkali land. With the development of science and technology, we should not only see the negative side, but should regard it as a very precious land resource. [0003] For agricultural planting in saline-alkali land, the first thing to consider is soil maturatio...

Problems solved by technology

However, the disadvantage of using compound fertilizer is that the fertilizer effect is too large, and the crops will die due to excessive fertilizer effect.

Moreover, compound fertilizers have strict requirements on geology, soil and climate, and do not use the promotion and use of saline-alkali land.

[0005] The soil maturation methods in the prior art have the following defects and deficiencies: the soil maturation effect in saline-alkali land is not ideal, the soil biomass is small, and the number of earthworms is very small, indicating that the degree of soil maturation is not enough; the soil aggregate structure is small, the bulk volume of the soil is large, and the total pores of the soil It is difficult to increase soil fertility and biomass in a short period of time, and reduce the pH value of saline-alkali soil in a short period of time by the soil maturation method of the prior art
