| 摘 要： | 通过对淀粉类保水、保肥性能的测定，研究淀粉类保水剂的保水性能。结果表明，不同的水介质、pH值、肥料液以及土壤环境都会影响保水剂的保水性能。此类淀粉保水剂不适合应用于盐分含量过高的土壤中，随着水溶液中NaCl含量的增加，其吸水率随之下降；在pH值为6.5的水溶液中吸水率最高；在以尿素为主要营养元素的氮类肥料液中吸水性最好，在壤土中的重复吸水性效果最好，当壤土中水分含量为75％时，持水效果最好。

| Abstract: | Based on the starch water retaining agent （SWRA ） , the water retention capacity and capacity were measured .The result showed that the performance of SWRA was affected by water medium ,pH value ,fertilizer fluid and soil environment . The SWRA is unsuitable for high salt content of soil . The water absorption rate decreased with the concentration of NaCl increased .The water absorption rate is highest at pH 6.5. The urea has the best water absorption in nitrogen fertilizer fluid .The loam has better repetitive water absorption capacity .When the water content of loam is 75% ,the water retention is the best . |
