Saline-alkali soil improvement method

Abstract

The invention relates to a saline-alkali soil improvement method, which uses saline-alkali soil improvement equipment. The saline-alkali soil improvement equipment comprises a base and a material mixing device, and the material mixing device is arranged on the upper surface of the base. The saline-alkali soil improvement equipment can solve the following problems at present: when existing mixing equipment is used for mixing saline-alkali soil and an improvement agent, the improvement agent is directly placed on the surface of the saline-alkali soil and then is stirred and mixed, the improvement agent is difficult to quickly permeate into the deeper part of the soil and is difficult to take effect rapidly, as a result, the improvement efficiency of the saline-alkali soil is reduced, in addition, when the saline-alkali soil is mixed with the improvement agent, a certain amount of water is added, slurry is formed by the soil and is easily deposited at the bottom of mixing equipment, the mixing equipment does not well turn up and stir the slurry, and therefore, the improvement effect of saline-alkali soil is reduced.

Description

technical field [0001] The invention relates to the field of soil management, in particular to a soil improvement method for saline-alkali land. Background technique [0002] Soil management can play a vital role in the improvement of the overall environment, especially for the improvement of saline-alkali soil; the improvement of saline-alkali soil is to improve the physical, chemical and biological properties of the soil. The improvement method is mainly to use agricultural Water conservancy engineering, physical chemistry and biotechnology and other comprehensive measures to deal with it; among them, the chemical method to improve alkaline soil refers to the application of chemical agents in alkaline soil, which can change the composition of colloidal adsorption ions in the soil , which in turn can improve the physical properties of the soil, increasing the soil structure and permeability, which is not only beneficial to soil desalination and suppression of counter-salt, ...

AI Technical Summary

Problems solved by technology

[0004] ①When the existing mixing equipment mixes the saline-alkali soil and the improvement agent, the improvement agent is directly placed on the surface of the saline-alkali soil and then stirred and mixed, making it difficult for the improvement agent to penetrate deeper into the soil quickly. As a result, it is difficult for the improvement agent to work quickly, thereby reducing the improvement efficiency of saline-alkali soil

[0005] ②When the existing mixing equipment mixes the saline-alkali soil with the improvement agent, a certain amount of water will be added when the saline-alkali soil is mixed with the improvement agent to make the soil form mud, and the mud has a certain fluidity and is easy to deposit on the mixture. The bottom of the equipment, and the mixing equipment does not turn up the mud well, so that the saline-alkali soil and the improvement agent cannot be fully mixed, thereby reducing the improvement effect of the saline-alkali soil
