Method for carrying out raw soil greening on heavy saline and alkaline land by using brassinolide-containing soil conditioner

Abstract

The invention relates to a method for carrying out raw soil greening on heavy saline and alkaline land by using a brassinolide-containing soil conditioner. The brassinolide-containing soil conditioner comprises, by weight, 25-27 parts of fermented sheep dung, 15-17 parts of fermented pig dung, 17-19 parts of fermented duck dung, 2-4 parts of fermented sawdust, 5-7 parts of ammonium sulfate, 4-6 parts of ammonium superphosphate, 3-5 parts of potassium chloride, 5-7 parts of ammonium bicarbonate, 2-4 parts of ammonium phosphate, 2-4 parts of ammonium chloride, 1-3 parts of gel powder, 1-3 parts of diatomite, 1-3 parts of pentanoic acid, 1-3 parts of amino acid salts, 0.5-0.7 parts of brassinolide, 0.5-0.7 parts of compound sodium nitrophenolate, 0.5-0.7 parts of Radix Scutellariae extract, 2-4 parts of tricalcium phosphate, 0.5-0.7 parts of a cellulose grafted acrylate polymer, 0.1-0.3 parts of Halobacterium salinarium, 0.1-0.3 parts of Bacillus coagulans, 0.1-0.3 parts of Trichoderma Longibrachiatum and 0.1-0.3 parts of fermented tea leaves.

Description

technical field [0001] The invention relates to a brassinolide-containing soil improver, in particular to a method for the original soil greening of severe saline-alkali land with a brassinolide-containing soil improver, belonging to the technical field of landscaping. Background technique [0002] In the process of utilization of saline-alkali land, simply put, it can be divided into light saline-alkali land, moderate saline-alkali land and heavy saline-alkali land. Light saline-alkali land means that its emergence rate is 70%-80%, and its salt content is below 3 per thousand; heavy saline-alkali land refers to its salt content exceeding 6 per thousand, and its emergence rate is less than 50%; The block is moderate saline-alkali soil (expressed in terms of pH value: mild saline-alkali soil pH value: 7.1-8.5, moderate saline-alkali soil pH value: 8.5-9.5, severe saline-alkali soil pH value: above 9.5). [0003] The method for carrying out original soil greening on severe sa...

AI Technical Summary

Problems solved by technology

[0004] (1) It cannot effectively reduce the pH value of the soil, and a high pH value is not conducive to the growth of plants;

[0005] (2) Insufficient ability to reduce soil salinity;

[0006] (3) The effect of increasing the content of humus, total nitrogen and available phosphorus in the soil is limited;

[0007] (4) When the plants are planted in the improved saline-alkali land, the transplanting survival rate is not high, and the biomass of branches and leaves is small
