一、保水剂的主要特性1.安全环保。保水剂无毒无味,不污染植物、土壤和地下水,土壤保水剂和防水土流失剂最终分解物为二氧化碳、水、氨态氮和钠或钾离子,无任何残留。2.保墒省水。可有效抑制水分蒸发,防止水土流失,即使在有灌溉的条件下,也可省水50%。3.改善土壤结构。施用保水剂能够使重粘土壤、砂土的土壤得到改良,同时促进土壤微生物发育,提高土壤 First, the main features of water-retaining agent 1. Safety and environmental protection. Water-retaining agent is non-toxic and tasteless, does not pollute plants, soil and groundwater, soil water-retaining agent and soil erosion agent final decomposition products of carbon dioxide, water, ammonia nitrogen and sodium or potassium ions, without any residue. 2. Preserved water and water. Can effectively inhibit the evaporation of water to prevent soil erosion, even in the irrigation conditions, but also save 50% water. 3. Improve soil structure. Application of water retaining agent can make heavy clay soil, sandy soil can be improved, while promoting soil microbial development, improve soil
