Method for performing mild saline-alkali land raw soil greening through biological modifier comprising fermented pig manure

Abstract

The invention relates to a method for performing mild saline-alkali land raw soil greening through a biological modifier comprising fermented pig manure. The biological modifier comprising the fermented pig manure comprises the following components in parts by weight: 16-20 parts of peat, 8-12 parts of perlite, 4-8 parts of fermented sawdust, 1-3 parts of ammonium chloride, 1-3 parts of calcium hydrogen phosphate, 1-3 parts of magnesium sulfate, 0.3-1 part of acetic acid, 1-3 parts of amino acid salt, 8-12 parts of the fermented pig manure, 8-12 parts of eggplant straw powder, 0.3-1 part of forchlorfenuron, 0.3-1 part of carbaryl, 0.1-0.5 part of a danshen extract, 0.5-2 parts of sodium silicoaluminate, 0.2-0.5 part of cellulose xanthogenate grafted acrylate, 0.1-0.3 part of halobacterium salinarium, 0.1-0.3 part of Methanosarcinaceae, 0.1-0.3 part of bacillus subtilis, 0.1-0.3 part of Bacillus licheniformis, 0.1-0.3 part of bacillus laterosporus and 0.1-0.3 part of azospirillum.

Description

technical field [0001] The invention relates to a bio-improvement agent containing fermented pig manure, in particular to a method for afforesting mild saline-alkali soil with a bio-improvement agent containing fermented pig manure, which belongs to the field of landscaping. Background technique [0002] Saline-alkali soil is a general term for saline soil and alkaline soil. Saline soil mainly refers to salinized soil with high chloride or sulfate content. The soil is alkaline, but the pH value is not necessarily high. Alkaline soil refers to the soil containing carbonate or heavy phosphate, the pH value is high, the soil is alkaline, the organic matter content of saline-alkali soil is small, the soil fertility is low, the physical and chemical properties are poor, and there are many anions and cations harmful to crops. Promote seedlings. The principle of fertilization in saline-alkali soil is mainly to apply organic fertilizers and high-efficiency compound fertilizers, an...

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
