Problems solved by technology

The saline-alkaline soil improver is solid, which solves the shortcomings of liquid soil improver, which is easy to infiltrate and volatilize, and can effectively improve the state of soil particles and improve soil water retention performance, but the effect is not very ideal, and the application range is not very wide. The seedling stage and production stage of planting plants are not practical, and the salinity and alkali that are turned up when encountering water cannot be treated. At the same time, plant hormones have certain pollution to the environment.

Abstract

The invention discloses a saline-alkali soil improver and a preparation method thereof. The saline-alkali soil improver contains the following components in parts by weight: 5-12 parts of bio-carbon,35-55 parts of calcined ardealite, 15-25 parts of honeycomb coal ash, 4-10 parts of modified zeolite, 5-8 parts of expanded perlite, 3-8 parts of humic acid powder, 2-6 parts of citric acid residue, 1-5 parts of poly-aluminum ferric silicate sulfate, 2-4 parts of diatomite, 0.5-1.5 parts of a calcium activating agent, 0.2-0.6 part of a compound biological bacteria agent and 3-7 parts of an organiccompound fertilizer. The saline-alkali soil improver is capable of effectively improving the physicochemical shape of saline-alkali soil within a short time and can take effect rapidly.

Description

technical field [0001] The invention relates to the technical field of soil improvement, in particular to a saline-alkaline soil improver and a preparation method thereof. Background technique [0002] Saline-alkali soil is a general term for saline soil and alkaline soil and various salinized and alkaline soils. Among them, saline soil refers to the soil that contains a large amount of soluble salts and makes most plants unable to grow, and its salt content is generally more than 0.6%; alkaline soil refers to the soil whose substitution rate (ESP) of sodium ion cation substitution exceeds 20%. strong alkaline soil. The physical and chemical properties of saline soil are poor. The main performance is that the salinity or alkalinity is too high, which leads to water shortage or poisoning of plant roots. Poor resistance, extremely unfavorable to agricultural production. [0003] To this end, the Chinese patent literature was searched. In the Chinese patent application lite...
