Problems solved by technology

[0003] At present, although the common water-retaining agents on the market have good water absorption capacity, their repeated water absorption and release capacity is weak, and the effect lasts for a short time after application. Moreover, long-term use will cause adverse effects such as soil compaction and pH increase, which is difficult to meet. actual requirements, and the production cost of the existing water-retaining agents is relatively high, which is not conducive to large-scale promotion and use

Abstract

The invention discloses a composite agricultural drought-resistant water conservation agent which is characterized by comprising the following components in parts by weight: 150-180 parts of carboxymethylcellulose, 6-10 parts of N,N-methylene bisacrylamide, 30-50 parts of humic acid, 700-1,000 parts of acrylamide, 60-80 parts of potassium persulfate, 200-375 parts of NaOH and 10,000-15,000 parts of distilled water. According to the composite agricultural drought-resistant water conservation agent disclosed by the invention, humic acid and carboxymethylcellulose are used as raw materials, and both are a natural material; particularly, humic acid is an important organic component of soil, and thus, the adverse reaction of soil caused by applying humic acid and carboxymethylcellulose is less than that caused by general synthetic substances; and meanwhile, since humic acid and cellulose are widely available and easy to get, the cost of the water conservation agent disclosed by the invention is lower than that of general water conservation agents, and the water conservation agent disclosed by the invention is more suitable for large-range popularization and application.

Description

Technical field [0001] The invention relates to the technical field of water-retaining agents, in particular to a composite agricultural drought-resistant water-retaining agent. Background technique [0002] my country's arid and semi-arid areas account for about 47% of the country's land area. Global warming has led to this trend of aridification that continues to increase. Although there is plenty of rainfall in some areas, the seasonal fluctuation of precipitation is also relatively large, and seasonal droughts often occur. Effective use of limited water resources is also one of the ways to solve water shortages. In addition, the utilization rate of fertilizers in agriculture and forestry in my country is low in the season, and fertilizer efficiency is decreasing year by year. Drought water shortage and low fertilizer utilization have become the bottleneck restricting the development of agriculture and forestry in arid and semi-arid areas. The research and development of drou...
