Saline-alkali soil amemdment, its preparing method and use

Abstract

The present invention discloses one kind of amendment for regulating the structure and physical and chemical state of saline-alkali soil and its preparation process. The amendment consists of polymaleic acid 0.1-20 weigh portions, citric acid 0.5-35 weigh portions, sodium dodecyl benzene sulfonate 1.0-15 weigh portions, ammonium sulfate 1.0-8 weigh portions, and trace elements 0.1-8 weigh portions mainly. It can regulate the structure and physical and chemical state of saline-alkali soil effectively, eliminate the toxic action of salt and alkali to crop fast and make plant grow normally in saline-alkali soil.

Description

technical field

[0001] The invention relates to a soil improver, in particular to a conditioner for regulating the structure and physical and chemical state of saline-alkali soil and a preparation method of the conditioner, belonging to the field of soil agricultural chemistry. Background technique

[0002] There are several billion mu of saline-alkali land in my country, mainly including primary saline-alkali soil and secondary salinized soil, which is one of the main reasons for further desertification of soil. As a resource, about 80% of saline-alkali land has not been developed and utilized in our country. For decades, the country has invested a lot of manpower and material resources in transforming saline-alkali land. However, due to the limitations of traditional transformation methods, it is still difficult to restrain the land Therefore, it is of great practical significance to develop a saline-alkali soil conditioner that can save water, be efficient, and be easy to...
