Method for carrying out raw soil greening on coastal beach saline and alkaline land by using cottonseed shell powder-containing salt absorbing agent

Abstract

The invention relates to a method for carrying out raw soil greening on coastal beach saline and alkaline land by using a cottonseed shell powder-containing salt absorbing agent. The formula of the cottonseed shell powder-containing salt absorbing agent comprises 24-26 parts of buckwheat straw powder, 12-14 parts of furfural residue, 6-8 parts of fermented marten manure, 6-8 parts of cottonseed shell powder, 3-5 parts of antigorite powder, 2-4 parts of diatomite, 2-4 parts of perlite, 2-4 parts of iron sulfate, 2-4 parts of magnesium hydrogen phosphate, 2-4 parts of ammonium nitrate, 2-4 parts of calcium superphosphate, 2-4 parts of potassium dihydrogen phosphate, 2-4 parts of sodium pentaborate, 1-3 parts of phthalic acid, 1-3 parts of amino acid salts, 0.5-0.7 parts of paclobutrazol, 0.5-0.7 parts of chlormequat chloride, 0.5-0.7 parts of carbaryl, 0.1-0.3 parts of hop extract product, 1-2 parts of a starch grafted acrylate polymer, 3-5 parts of potassium ferrocyanide, 0.1-0.3 parts of Halobacillus halophilus, 0.1-0.3 parts of Bacillus subtilis, 0.1-0.3 parts of baker's yeast and 0.1-0.3 parts of Azotobacter vinelandii.

Description

technical field [0001] The invention relates to a salt-absorbing agent containing cottonseed hull powder, in particular to a method for performing original soil greening on coastal beach saline-alkali land with a salt-absorbing agent containing cottonseed hull powder, belonging to the technical field of original soil greening. Background technique [0002] Tidal flats are the general term for beaches, river beaches and lake beaches, and refer to the tidal flooding zone between the high tide level and low tide level of the coastal spring tide, the beach between the normal water level and the flood level of rivers and lakes, the beach below the flood level of seasonal lakes and rivers, reservoirs, The beach area between the normal water storage level and the maximum flood level of the pond. In geomorphology, it is called "intertidal zone". Due to the effect of the tide, the tidal flat is sometimes submerged by water and sometimes exposed to the water surface, its upper part i...

AI Technical Summary

Problems solved by technology

[0005] (1) It cannot effectively reduce the salt content in the tidal flat saline-alkali soil;

[0006] (2) The soil's ability to retain fertilizer is poor, and it is easy to lose fertilizer after application;

[0007] (3) The water retention capacity of the soil is poor, the water is easy to lose, and the moisture content in the soil is low;

[0008] (4) It cannot effectively reduce the pH value of the soil;

[0009] (5) The survival rate of native plants is low and the growth is slow
