| 摘 要： | 采用紫外(UV)光引发法合成了高吸水树脂聚丙烯酸(钠),吸蒸馏水倍率4100 g/g,吸盐水(质量分数0.9%的NaCl溶液)倍率达405 g/g.并用傅里叶变换红外光谱(FTIR)和热重分析(TG)对其进行了表征.通过室内模拟试验,探讨了砂土和溶液中水量、时间、pH值、温度、肥料对聚丙烯酸钠吸液倍率的影响;通过盆栽试验进一步研究了聚丙烯酸钠对土壤保水性能及出苗影响.试验结果表明:(1)在砂土中,聚丙烯酸钠的吸液倍率比溶液中低,吸液饱和时间比溶液中长;(2)pH值(4～11),温度(20℃～70℃)对聚丙烯酸钠吸液倍率影响不大;(3)非电解质肥料对吸液倍率影响很小,电解质肥料对吸液倍率影响较大;(4)盆栽实验表明该聚丙烯酸钠对提高出苗率及土壤保水有很大改善.
