地膜覆盖对农田径流中氮磷流失的影响
The Effected of Mulch Film on Nitrogen and Phosphorus Loss in Agricultural Runoff
摘要
Abstract
[ Objective] The aim of the study was to seek a good way to reduce nitrogen and phosphorus loss in agricultural runoff. [ Method] The effect of three kinds of mulch film: plastic film mulching, straw mulching,none mulching on nitrogen and phosphorus loss in agriculture was investigated. [Result]The results showed that: Although mulching increased runoff,reduced the rains washed out planting soil,so the concentration and total loss of nitrogen and phosphorus in runoff was lowered; The land of plastic film mulching add more runoff,but total loss of nitrogen and phosphorus was lowest; The land of straw mulching had a little more total loss of nitrogen and phosphorus then the land of plastic film mulching,but the output of crops was higher then the land of plastic film mulching and none secondarypollutant. [ Conclusion] Straw mulching could reduce nitrogen and phosphorus loss in agricultural runoff, improve the output of crops and no secondarypollutant emission. So straw was a good cultivated ways.关键词
