| 摘 要： | 目的]为探究降解地膜覆盖对径流及溶解态氮磷流失的影响。方法]利用野外原位径流小区，以覆膜垄作花生种植为研究对象，设置0.003 mm厚聚乙烯普通地膜覆盖处理(PF)和厚度为0.006 mm(BF1),0.008 mm(BF2),0.010 mm(BF3),0.012 mm(BF4)的降解地膜覆盖处理及未覆膜处理(CK),测定不同处理在自然降雨条件下的径流量及径流中铵态氮(NH4+—N)、硝态氮(NO3-—N)、速效磷(PO43-—P)浓度，分析不同厚度降解地膜覆盖条件下径流及养分流失特征。结果](1)降解地膜降解所需时间随地膜厚度的增加而增加。(2)各处理的累积径流量由小到大为BF14+-N和NO3<...
