摘　　要：耐盐性不高是目前保水剂推广的关键技术瓶颈,为解决这一技术难点,本研究从工农业废弃物中筛选有机及无机成分,制成保水构件,与市售保水剂(聚丙烯酰胺)进行保水和耐盐性系列比较试验。结果显示,新型保水材料的耐盐力和保水保肥性均优于市售保水剂,而且成本较低,应用于农林业的前景广阔。The low salt resistance is the key technical bottleneck for water retaining agent promotion.to solve this technical difficulty,organic and inorganic components were selected from industrial and agricultural wastes to make water retaining components,and carry out a series of comparative tests on water conservation and salt tolerance with commercial water retaining agent(polyacrylamide).The results showed that the salt tolerance and fertilizer retention of the new type of water retaining materials were better than the commercial water retaining agent,and the cost is lower,showing a broad application prospect in agriculture and forestry.
