不同配比的蔬菜与玉米间套作削减农田径流污染的研究
Reduction of Runoff from Cultivated Land with Intercropping System of Different Ratio of Vegetables to Maize
摘要
Abstract
The field experiment was conducted under natural rainfall condition during July to September in year 2011 to study the surface runoff and the loss of TN, TP, COD and SS from cultivated land with different ratio of vegetables to maize intercropping system in Dianchi Lake watershed. The results showed that①The loss of surface runoff from cultivated land with vegetables mono-cropping was 73.78 m3'hm-, with TN, TP, COD and SS loss of 0.79, 0.195, 2.86 kg-hm-2 and 44.46 kg'hm-2, respectively. ②The surface runoff from intercropping system of ratio of maize to cauliflower-pumpkin 1:2 was 41.06 m3'hm-2, the loss of TN, TP, COD and SS loss of 0.41, 0.112, 1.08 kg'hm-2 and 13.06 kg'hm-2, respectively. ③The surface runoff and TN, TP, COD and SS loss of from intercropping system with maize to cauliflower-pumpkin 1: 2 were lower than 1:3 and 1:4.④Comparing with cauliflower-pumpkin mono-cropping system, the surface runoff,TN,TP, COD and SS from intercropping system of 1=2 ratio were reduced by 44.35%, 48.49 %, 42.38%, 62.13% and 72.92%, respectively. Therefore, the intercropping system of 1 -2 ratio was the most optimal for control of surface runoff and nutrient loss.关键词
