| 摘 要： | 研究了施用不同剂量的聚丙烯酰胺后,0-20 cm土层的土壤含水量、不同天气情况下的土壤含水量以及观测期始末土壤含水量的变化,结果表明:几种处理中,施用剂量为75 kg/hm~2的处理土壤含水量最高;观测后期与观测前期比较以75 kg/hm~2处理土壤含水量相差最小;10—20 cm土层土壤含水量降幅小于0—10 cm土层。

| Abstract: | It studies the daily soil moisture of 0-20 cm layer,the soil moisture under different weather conditions and the variations of whole process soil moisture during observation after fertilizing different dosage of polyacrylamide.The outcomes show that among the methods,the soil moisture of fertilizing dosage 75 kg/hm~2 is the highest;comparing with the early and late observation periods,the difference of treated soil moisture of 75 kg/hm~2 is the smallest and;the range of decrease of 10-20 cm layer soil moisture is smaller than that of 0-10 cm layer. |
