Saline-alkali soil improvement and restoration method

Abstract

The invention relates to a saline-alkali soil improvement and restoration method. A base, a grinding device and a chemical box are included, the grinding device is installed at the left end of the upper end face of the base, the chemical box is installed at the lower end of the left end face of the grinding device, and the lower end face of the chemical box is connected with the upper end face ofthe base. Saline-alkali soil is fully crushed by adopting a design concept of grinding, and the arranged grinding device can achieve a function of fully grinding the soil, so that the soil crushing rate is increased, and the subsequent soil improvement and restoration rate and utilization rate are further increased.

Description

technical field [0001] The invention relates to the technical field of soil remediation, in particular to a saline-alkaline soil improvement and remediation method. Background technique [0002] Saline-alkali refers to the mixture of sodium chloride and sodium carbonate, and saline-alkali land is a type of salt accumulation, that is, the salt contained in the soil affects the normal growth of crops, acidic soil is loose in texture, and has strong air permeability and water permeability; alkaline The soil texture is hard, easy to harden into lumps, poor ventilation and water permeability Saline-alkali soil Saline soil surface layer (0-20 cm) contains a large amount of soluble salt (0.6-2% or more), generally in arid climates with little rain, large evaporation, It is formed under the influence of natural conditions such as low terrain, high groundwater level, and high salinity and human activities. In addition, there is residual saline soil formed by ancient salt accumulation...

AI Technical Summary

Problems solved by technology

[0003] 1. When saline-alkaline soil is repaired with a repairing agent, it is easy to cause the repairing agent to permeate and uneven soil absorption when used directly, which will lead to poor repairing effect of the soil or too long repairing time. Therefore, before using the repairing agent, it is necessary to Grinding and pulverizing it;

[0004] 2. In the process of grinding and crushing the soil, the soil is easy to adhere to the grinder, causing soil loss and affecting the subsequent soil utilization rate, and it is extremely easy to cause poor soil crushing effect due to insufficient grinding, which in turn affects the subsequent effect of soil remediation
