Description

technical field

[0001] The invention relates to a water-retaining agent, more specifically to a composite water-retaining agent for soil and its preparation method and application, belonging to the field of agricultural technology. Background technique

[0002] In my country, arid and semi-arid areas account for more than 50% of the country's land area, but the soil's water holding capacity is low, and it is easy to evaporate, and the utilization of water itself is low. Therefore, the drought problem has increasingly become a problem that plagues my country's agriculture and forestry. big problem

[0003] In recent years, soil water retaining agent, as a new type of composite additive that can effectively enhance soil water holding capacity and water retention capacity, has made many important progress in the fields of soil structure improvement, agricultural water retention and drought resistance;

[0004] There are many related reports about water retaining agents in the p...
