Problems solved by technology

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 The problem of salinization, so it is of great practical significance to develop a saline-alkali soil conditioner that can save water, be efficient, and be easy to use as soon as possible.

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...
