| 摘 要： | 聚丙烯酰胺(PAM)是一种新型高效土壤结构改良剂,对适宜的土壤它可抑制土壤表面结皮,增加土壤水分入渗。研究表明,土壤结构是影响施用PAM效果的决定性因素,粗砂土施用后可以增加径流量、减小产沙量,而壤土施用后径流量和产沙量都减小了,并且减少产沙量的效果要好于减少径流量的效果。壤土PAM的施用量以1.4 g/m2较为合适。

| Abstract: | PAM is a new and high efficient agent for improving the soil structure.It can control surface crusting of eligible soil and increase infiltration.It shows through study that soil structure is a critical factor that effects the PAM outcome,can increase runoff and reduce the quantity of sediment production after applying in coarse sandy loam,both runoff and sediment production are reduced after applying in loam and the effects of sediment production reduction is better than that of the runoff reduction.The better amount of PAM application in loam is(1.4 g/m~2.) |
