摘　　要：考察了含有腐植酸的吸水性树脂(HA-MA-AM)在溶液以及土壤环境中的性质。当腐植酸钾用量低于40wt%时,在环境pH值为6～7的条件下,HA-MA-AM的吸水倍率明显高于未添加腐植酸钾的MA-AM型保水剂。实验结果表明,HA-MA-AM具有较好保持水分、抑制水分蒸发的作用。In this paper, various properties of a new super-absorbent resin humic acid （HA-MA-AM） in solution and soil environment were investigated. The results showed that when potassium hnmate content is lower than 40 wt% and environment pH is 6～7, water absorbency of HA-MA-AM is higher than that of MA-AM no added with potassium humate obviously. HA- MA- AM application in agriculture and horticulture could retain soil water and inhibit water evaporating efficientively.
