Abstract

The invention belongs to application products in the field of agricultural land improvement and protection, relates to a saline-alkali soil remediation agent and aims to provide a saline-alkali soil remediation agent for treatment of agricultural saline-alkali soil and a preparation method of the saline-alkali soil remediation agent. By adoption of the saline-alkali soil remediation agent, saline-alkali land can be improved into arable land to increase yield of the saline-alkali land. The saline-alkali soil remediation agent is characterized by being prepared by mixing, by weight, 61-99% of polymaleic anhydride, 1-10% of gamma-polyglutamic acid and the balance water. The saline-alkali soil remediation agent has advantages of low production cost, simplicity in preparation, convenience in operation, quickness and high efficiency in saline-alkali soil improvement and the like.

Description

technical field [0001] The invention relates to a saline-alkali soil restoration agent, which belongs to the technical field of application products for agricultural cultivated land promotion and protection. Background technique [0002] Saline-alkali soil is a type of salt accumulation, which means that the salt contained in the soil affects the normal growth of crops. According to incomplete statistics from UNESCO and FAO, the area of ​​saline-alkali land in the world is 954.38 million hectares, of which Our country is 99.13 million hectares. In the arid and semi-arid areas of Northeast, Northwest, and North China, where precipitation is small and evaporation is large, salt dissolved in water tends to accumulate on the soil surface, forming soil salinization. The formation of alkaline soil and alkalized soil in my country is mostly related to the accumulation of carbonate in the soil, so the degree of alkalization is generally high, and plants in severe saline-alkali soil...
