The scatter super absorbent polymer in soil surface do n ' t influenced the infiltration process of trickle source , the wetting front is almost coincide with checking treatment . ( 4 ) because of the influence of soil water redistribution , the volume of wetted soil increase and the average soil water content decrease . in case of applied water 330min with a discharge rate 1 l / h , the horizontal an O ）土壤湿润体的体积在水分再分布的作用下，随看停水时间的增加而不断变大，对滴头流量为几儿供水330min况停水后的水分再分布观测表明，到停水4000min时，垂向湿润距离增加了25 ，水平湿润距离增加了16 ，湿润体的体积增加了68 ，湿润体的平均体积含水率由停水时刻的0
