保水剂是一种能保水、固土、保肥的高分子化合物,能通过自身具有的保水特性以及土壤学作用机制,将土壤结构改善,有效降低土壤密度,将土壤抗蚀性提高,达到水土保持的目的。文章通过介绍保水剂的功能以及保水剂在水土保持中的作用,并指出保水剂现目前存在的问题,并提出保水剂在水土保持中的具体使用方法,让保水剂在水土保持中发挥更大作用。
Water-retaining agent is a kind of macromolecule compound which can retain water, soil and fertilizer, and can improve the soil structure through its own water retaining property and soil action mechanism, effectively reduce the soil density, increase soil corrosion resistance, Maintain the purpose. The article introduces the function of water-retaining agent and the function of water-retaining agent in soil and water conservation, and points out the existing problems of water-retaining agent. It also proposes the specific use of water-retaining agent in water and soil conservation so as to make the water- effect.
