Abstract

The invention provides a saline-alkali soil repairing agent, and the saline-alkali soil repairing agent is characterized by being prepared from the following raw materials in parts by weight: 25-35 parts of a ferrous fumarate organic acid copolymer, 5-10 parts of seaweed powder, 15-20 parts of a microbial fertilizer, 10-15 parts of calcium lignosulphonate, 5-10 parts of humic acid and 50-60 partsof water. The invention also provides a preparation method of the saline-alkali soil repairing agent and a repairing method for repairing saline-alkali soil by utilizing the saline-alkali soil repairing agent, by utilizing the embodiments of the present application, the saline-alkali soil can be safely, rapidly and efficiently repaired, the repairing cost is reduced, the production of secondary pollution is reduced, the yield of the saline-alkali soil is remarkably improved, and the quality of agricultural products is obviously improved.

Description

technical field [0001] The application relates to the technical field of agricultural soil restoration, in particular to a saline-alkali soil restoration agent and a restoration method for saline-alkali soil restoration using the soil restoration agent. Background technique [0002] Soil is an important resource for human survival, but land salinization has caused the destruction of resources, the huge loss of agricultural production and the threat to the biosphere and ecological environment. At present, the area of ​​saline-alkali soil in my country accounts for about 60% of the country's land area. The salt contained in this kind of soil affects the normal growth of crops. It has characteristics such as high pH value, high harmful salt content, poor air permeability, easy to form plates, and low fertility, which affects the sustainable development of agriculture and the normal life of human beings. and healthy. Therefore, the remediation of saline-alkali soil has always ...
