Description

technical field [0001] The invention relates to the field of soil treatment and restoration equipment, in particular to a large-capacity restoration device for soil treatment in saline-alkali land. Background technique [0002] With the development of the times, people's living standards are constantly improving, but our living environment is constantly deteriorating. At present, the area of ​​saline soil in my country is about 34.6 million hectares, and the salinization of cultivated land is 7.6 million hectares, nearly 1 / 5 Salinization of cultivated land occurs, so the improvement and restoration of saline-alkali land is of great significance to land governance and ecological environment protection. At present, saline-alkali land improvement technologies include physical improvement, hydraulic improvement, chemical improvement, and microbial improvement. Among them, physical improvement has a large amount of engineering , the effect is not obvious; hydraulic improvement cons...

[0002] With the development of the times, people's living standards are constantly improving, but our living environment is constantly deteriorating. At present, the area of ​​saline soil in my country is about 34.6 million hectares, and the salinization of cultivated land is 7.6 million hectares, nearly 1 / 5 Salinization of cultivated land occurs, so the improvement and restoration of saline-alkali land is of great significance to land governance and ecological environment protection. At present, saline-alkali land improvement technologies include physical improvement, hydraulic improvement, chemical improvement, and microbial improvement. Among them, physical improvement has a large amount of engineering , the effect is not obvious; hydraulic improvement consumes too much water resources, and only improves the salt content of saline-alkali land; chemical improvement, such as using gypsum, olivine, etc. to repair saline-alkali land, is more effective in reducing the alkaline content of saline-alkali land, but the cost is high , it is difficult to promote in a large area; microbial improvement, through the growth and reproduction of microorganisms, can promote the movement of salt in the soil, effectively transform organic fertilizers in the soil into humus, and improve soil salinity

[0003] However, the soil in saline-alkali land is usually poor and lacks the nutrients needed for microbial growth and reproduction, so the effect of microbial improvement has certain limitations. For the soil restoration of saline-alkali land, we mostly use chemical soil remediation agents for improvement.

However, the current saline-alkali soil remediation equipment has low working efficiency and poor repair effect, and cannot meet the needs of large-capacity saline-alkali soil remediation, and has poor practicability
