摘要
为探明种植模式对农田径流污染的影响,寻求控制农田径流污染的有效种植模式,对不同种植模式下的小区径流量和径流污染(TN,TP,CODCr和SS)进行了测定.结果表明:蔬菜单作模式的农田径流量和径流污染明显大于玉米与蔬菜间作模式;玉米与蔬菜间作模式可削减农田地表径流量和径流污染,其中玉米‖青花-马铃薯间作模式削减污染效果最好,与其对应的蔬菜单作模式——青花-马铃薯单作模式相比,该间作模式可削减79.59%的径流量,86.87%TN,84.23%TP,91.41%CODCr和82.46%SS的流失量.
In order to explore the effects of different planting patterns for the effective control of farmland runoff contamination,loss of TN,TP,CODCr and SS under different planting patterns were analyzed with field plot experiments.The results showed that the surface runoff,loss of TN,TP,CODCr and SS under a mono-cropping system were higher than under a maize and vegetables intercropping system.The surface runoff,loss of TN,TP,CODCr and SS could be reduced using a maize and vegetables intercropping system.The maize‖cauliflower/potato intercropping pattern was the most effective.Comparing with cauliflower/potato mono-cropping system,its reduction percentages of surface runoff,TN,TP,CODCr and SS were 79.59%,86.87%,84.23%,91.41% and 82.46%,respectively.
