摘  要:
节约水资源是当今最重要的环境问题之一,保水剂属于高吸水性树脂,对水具有化学吸附的作用,能够有效的避免水分的流失浪费。将保水剂应用到土壤中,可以很好的达到节水的目的。土壤保水剂的制备方法有多种形式,但总的作用机理即借助亲水性基团与水发生水合作用,形成氢键。土壤保水剂作为直接与植物接触的物质,必须对植物无副作用,且要对土壤本身没有影响,不能够改变土壤的酸碱度和含盐量。土壤保水剂的应用和研发虽然一直在进行,但是实际应用仍不够广泛,降低生产成本和系统化的定量研究等问题仍待解决。

摘  要:
Conservation of water resources is one of the most important environmental issue, water retention agent is a super absorbent polymer,it has chemical adsorption effect on water, can effectively avoid the waste of water loss. It can do well to achieve the purpose of saving water with water retention agent. The preparation method of soil water retention agent has a variety of forms, but the total mechanism is to form hydrogen bonds with the aid of hydrophilic groups and water hydration. Soil water retention agent contacts with plants directly, so it must have no side effects on the plant and the soil itself, similarly can not be able to change in edaphic ph and salinity. Soil water retention agent application and development has been going on though, but the practical application is still not enough broad, reduce the production cost and systematic quantitative research problems remain to be solved.
