Method for performing raw soil greening on sulfate-contained sandy soil through soil improvement fertilizer comprising biological agent

Abstract

The invention relates to a method for performing raw soil greening on sulfate-contained sandy soil through a soil improvement fertilizer comprising a biological agent. The soil improvement fertilizer comprises the following components in weight part: 21-23 parts of fermented cow dung, 6-8 parts of sweet potato seedling powder, 2-4 parts of orange peel powder, 1-3 parts of soybean meal, 5-7 parts of diatomite, 2-4 parts of perlite, 4-6 parts of fermented sawdust, 2-4 parts of eggshell powder, 2-4 parts of triple superphosphate, 2-4 parts of disodium hydrogen phosphate, 2-4 parts of ammonium bicarbonate, 1-3 parts of oxalic acid, 2-4 parts of amino acid salt, 0.5-0.7 parts of mulberry leaf extract, 0.3-0.4 parts of gibberellins, 0.2-0.4 parts of diethyl aminoethyl hexanoate, 0.1-0.3 parts of forchlorfenuron, 2-4 parts of potassium ferrocyanide, 0.5-0.7 parts of starch grafted acrylate polymer, 0.1-0.3 parts of sodium molybdate, 0.1-0.3 parts of bacillus coagulans, 0.1-0.3 parts of bacillus megaterium, 0.1-0.3 parts of azotobacter vinelandii, 0.1-0.3 parts of bacillus mucilaginosus, 0.1-0.3 parts of aspergillus oryzae and 0.1-0.3 parts of trichoderma longibrachiatum.

Description

technical field [0001] The invention relates to a soil-improving fertilizer containing biological inoculants, in particular to a method for soil-improving fertilizer containing biological inoculants to green the sandy soil containing sulfate, belonging to the technical field of landscaping. Background technique [0002] The main fertility characteristics of sandy soil are weak water storage capacity, low nutrient content, poor fertilizer retention ability, rapid soil temperature change, but good aeration and water permeability, and easy farming. Because the sandy soil contains more sand particles, less clay particles, and relatively large inter-particle voids, the water storage capacity is weak and the drought resistance ability is poor. The sandy soil itself is relatively poor in nutrients. Due to the lack of clay (inorganic colloid) and OM (organic colloid), the fertilizer retention is poor; the aeration and water permeability are good, which is conducive to the activity o...

AI Technical Summary

Problems solved by technology

[0004] (1) It cannot effectively reduce the sulfate content in sandy soil containing sulfate;

[0005] (2) The improved sandy soil loses its fertility too quickly, reducing the fertilizer efficiency of the soil;

[0006] (3) It cannot effectively change the acidic soil quality of sandy soil containing sulfate;

[0007] (4) The water retention capacity of the soil is poor, and the moisture content of the soil is low;

[0008] (5) The content of available phosphorus in the soil is low, which cannot meet the growth needs of green plants in the original soil;

[0009] (6) The content of trace elements in the soil is low, which cannot meet the trace element molybdenum required for the growth of green plants in the original soil
