Abstract

The present invention discloses a soil conditioner having the following formula: 1-15 parts of an unsaturated acid, 25-35 parts of a polyamine polyamide copolymer, 10-25 parts of cellulose ethers, 20-30 parts of a polyethylene oxide (polypropylene oxide) ether defoamer, 4-8 parts of a self-cleaner and 20-50 parts of water. The soil conditioner can significantly improve the physical and chemical properties of salinization soil, removes oil in the soil, accelerates salt infiltration, and neutralizes soil alkalinity.

Description

technical field [0001] The invention belongs to the technical field of agricultural chemistry, and in particular relates to a soil conditioner. Background technique [0002] my country is a large agricultural country, but not a strong one. The total area of ​​saline-alkali land in the country is 1,487 million mu (1 mu ≈ 667 m2), of which 554 million mu is saline soil and 673 million mu is residual salinized soil. Potential salinized soil is 260 million mu. Soil salinization refers to the phenomenon that the soil contains too much salt, which makes crops less productive or unable to grow. When the salt content of the soil surface exceeds 0.3%, the yield of crops will decrease significantly; when the salt content of the soil surface exceeds 0.6%, most plants cannot grow; when the salt content of the soil surface exceeds 1.0%, Only some plants specially adapted to saline soil can grow. Soil salinization is very harmful to agricultural production. On the one hand, it causes so...
