Problems solved by technology

The saline-alkali soil conditioner is solid, which solves the shortcomings of liquid soil conditioners that are easy to infiltrate and volatilize. It can effectively improve the state of soil particles and improve soil water retention performance, but the effect is not very satisfactory, and the application range is not very wide. The seedling and production stages of various plants are not practical, and the salinity that has been turned up by the water cannot be treated. At the same time, plant hormones have certain pollution to the environment.

Abstract

The invention discloses a saline alkali soil conditioning agent. The saline alkali soil conditioning agent comprises, by weight, 9 parts of biological charcoal, 45 parts of calcined phosphogypsum, 20parts of honeycomb briquette ash, 7 parts of modified zeolite, 6.5 parts of expanded perlite, 5.5 parts of humic acid powder, 4 parts of citric acid residue, 3 parts of polysilicate aluminum ferric, 3parts of diatomite, 1 part of a calcium activator, 0.4 part of a composite biological inocula, and 5 parts of an organic composite fertilizer. The saline alkali soil conditioning agent is capable ofimproving saline alkali soil physical and chemical properties effectively, improving time is short, and effect is achieved quickly.

Description

technical field [0001] The invention relates to the technical field of soil improvement, in particular to a saline-alkali soil conditioner. 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 literature "saline-alkali soil condi...
