Method for performing raw soil greening on coast saline land through biological modifier containing fly ash

Abstract

The invention relates to a method for performing raw soil greening on coast saline land through a biological modifier containing fly ash. The biological modifier comprises the following components in weight part: 8-12 parts of ceramsite, 11-15 parts of vermiculite, 1-5 part of fly ash, 0.5-2 parts of iron chloride, 0.5-2 parts of calcium dihydrogen phosphate, 0.2-1 parts of formic acid, 1-4 parts of amino acid salt, 2-6 parts of fermented sheep manure, 2-7 parts of capsicum straw powder, 0.3-1 parts of compound sodium nitrophenolate, 0.3-1 parts of amino-oxyacetic acid, 0.3-1 parts of soybean germ extract, 0.5-2 parts of potassium ferrocyanide, 0.2-0.5 parts of cellulose cellulose grafted acrylic acid salt, 0.1-0.5 parts of halomonas, 0.1-0.5 parts of Bacillus subtilis, 0.1-0.5 parts of azotobacter vinelandii, 0.1-0.5 parts of Aspergillus oryzae and 0.1-0.5 parts of Trichoderma longibrachiatum.

Description

technical field [0001] The invention relates to a fly ash-containing bio-improvement agent, in particular to a method for the fly ash-containing bio-improvement agent to carry out original soil greening on coastal saline-alkali land, and belongs to the technical field of landscaping. Background technique [0002] Soil salinization is a worldwide problem. The area of ​​saline-alkali land in the world is nearly 1 billion hectares. According to the second soil census in my country, the area of ​​saline-alkali land resources is about 527 million mu, of which 88 million mu is saline-alkali cultivated land, mainly distributed in North China and Northwest China. and the arid and semi-arid regions of the Northeast. All kinds of saline-alkali soils are formed under certain natural conditions. The essence of their formation is mainly the redistribution of various soluble salts in the horizontal and vertical directions on the ground, so that the salt gradually accumulates on the soil su...

AI Technical Summary

Problems solved by technology

[0004] (1) The ability and effect of reducing soil salinity are limited;

[0005] (2) The air permeability of the soil is poor, which affects the gas exchange of the soil;

[0006] (3) The pH of the soil is high, which is not suitable for the growth of green plants in the original soil;

[0007] (4) The water holding capacity of the soil is poor, resulting in weak water holding and water holding capacity of the soil;

[0008] (5) Cannot effectively reduce the alkalinity of the soil
