Water retaining agent for soil

Abstract

The invention discloses a water retaining agent for soil. The water retaining agent is prepared from, by weight, 17-20 parts of spirulina residues, 2.5-4.5 parts of chitosan oligosaccharide, 10-15 parts of a nanometer waterborne bonding agent, 30-50 parts of anionic polyacrylamide, 5-10 parts of acrylonitrile, 10-18 parts of monoammonium phosphate, 10-20 parts of Maya blue powder, 10-20 parts of citrus peel fermentation powder, 10-20 parts of oyster shell powder, 20-40 parts of rotten municipal sludge, 15-20 parts of duckweed freeze-dried powder, 5-10 parts of ferric sodium edelate, 10-20 parts of sugar alcohols magnesium, 3-6 parts of a mixed microbial agent and 3-5 parts of ferroferric oxide. According to the water retaining agent for the soil, the water-retaining property is good, so that the loss rate of dissolved fertilizer elements is significantly decreased; in addition, the organic matter content of the soil can be increased, and both negative ions and positive ions can be adsorbed.

Description

technical field [0001] The invention relates to the field of soil improvement, in particular to a soil water retaining agent. Background technique [0002] Water and fertilizer are two important factors affecting agricultural production. However, on the one hand, the low utilization rate of conventional water-soluble chemical fertilizers and serious fertilizer losses have become a major problem restricting agricultural production efficiency and affecting the environment. New fertilizers are an effective technology to increase the utilization rate of chemical fertilizers and reduce fertilizer losses. On the other hand, the shortage of water resources makes the urgency of agricultural water saving increasingly stronger. The use of water-retaining agents in dryland agriculture and water-saving agriculture has become an important water-saving technology. The integrated development of fertilizers and water-retaining agents to develop water-retaining functional fertilizers is an...
