摘要：本文阐述了保水剂的研究开发历史、种类、特点和作用机理 ,综述了保水剂对土壤理化性质的影响及其在林业上的应用情况。保水剂是一种吸水倍率高、保水性能好的高分子化合物。它可以提高土壤含水量、抑制土壤蒸发、改善土壤结构、增强土壤对养分的吸附力。保水剂在林业上的应用方法主要有拌土、拌种、包衣、根部涂层和用作培养基质等。在林业生产中应用保水剂可使种子提前发芽、提高出苗率和移植成活率、促进植物生长发育、延缓凋萎时间等。
The history of research and production, classification, characteristics and functional mechanism of water retaining agent were elaborated, and its influence on the soil and application in forestry were reviewed. Water retaining agent was an absorbing water polymer whose multiplying power was high and property of holding water was good. Water retaining agent could raise the soil water content, restrain water evaporation in the soil and improve the structure of soil, as well as enhance the absorption of nutrient in the soil. In forestry water retaining agent was mixed with soil, seeds, roots and culture medium. Water retaining agent could advance germination of seeds, improve emergence of seedlings and survival rate of trees, promote the growth of plants, and lengthen the withering time of plants. There was a wide range of application of water retaining agent in the afforestation in drought areas.
