Method for carrying out original-soil greening on sandy soil mainly containing chloride through soil improvement fertilizers with chelated iron

Abstract

The invention relates to a method for carrying out original-soil greening on sandy soil mainly containing chloride through soil improvement fertilizers with chelated iron. The soil improvement fertilizers with the chelated iron are prepared from, by weight, 19-21 parts of fermented cow dung, 14-16 parts of fermented duck dung, 6-8 parts of tomato straw powder, 1-3 parts of perlite, 3-5 parts of slag, 1-3 parts of desulfuration waste, 1-3 parts of potassium sulfate, 1-3 parts of ferric sodium pyrophosphate, 1-2 parts of the chelated iron, 2-4 parts of chelated zinc, 1-2 parts of amino acid salt, 0.5-1 part of propionic acid, 0.3-0.5 part of aminoethoxyvinylglycine, 0.3-0.5 part of aminooxyacetic acid, 0.1-0.3 part of radix curcuma extract, 1-2 parts of tricalcium phosphate, 0.5-1 part of starch xanthogenate-grafted acrylate, 0.3 part of halococcus, 0.05-0.1 part of halophilic halobacillus, 0.1-0.3 part of bacillus thuringiensis, 0.05-0.1 part of bacillus laterosporus and 0.1-0.3 part of brown nitrogen-fixing bacteria.

Description

technical field [0001] The invention relates to a soil improvement fertilizer containing chelated iron, in particular to a method for performing soil greening on sandy soil mainly containing chlorides with a soil improvement fertilizer containing chelated iron, which belongs to the field of landscaping . Background technique [0002] Sandy clay soil generally refers to a type of soil similar to sandy soil, with a physical clay content of 15%, which is mainly distributed in the piedmont plains of Xinjiang, Gansu, Ningxia, Inner Mongolia, and Qinghai, as well as on both sides of rivers in various places in Northwest my country. , Coastal Plain area. [0003] Applying soil improvement fertilizers to sandy clay soils is a common method for improving sandy clay soils. The deficiencies of prior art soil improvement fertilizers in improving sandy clay soils are as follows: [0004] (1) Insufficient ability to improve the content of chloride ions and sodium ions in sandy clay; [...

AI Technical Summary

Problems solved by technology

[0004] (1) Insufficient ability to improve the content of chloride ions and sodium ions in sandy clay;

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

[0007] (4) The effect of increasing the content of humus, total nitrogen and available phosphorus in the soil is limited;

[0008] (5) Cannot effectively reduce soil bulk density;

[0009] (6) When the plants are planted on the improved sandy clay soil, the transplanting survival rate is not high, and the biomass of branches and leaves is small
