摘要
通过巢湖流域麦-稻轮作制度下小麦田块养分流失监测试验,研究了巢湖流域种植业污染源的特性及其排污系数.研究结果表明,在施肥处理一定的情况下,氮磷流失量与降雨量成正相关性;在不同的施肥处理下,氮磷的流失量受肥料品种、施肥量以及施肥方式的影响.研究结果对于定量分析巢湖流域农田氮磷流失具有重要意义.
The planting pollution factor and sewage coefficient of Chao Lake Basin are studied by the experiment of wheat and rice crop rotation rotation system.The results show that in certain fertilization treatment,the loss of nitrogen and phosphorus has a positive correlation to rainfall.In different treatments,the species,amount and mode of fertilization have effect on the loss of nitrogen and phosphorus.The results have great significance for quantitative analysis of the loss of nitrogen and phosphorus.
