基于第一次云南污染源普查的种植业肥料流失特征与流失系数应用分析

Application of Fertilizer Loss and the Loss Efficient of Planting Industry based on the First General Survey of Pollution Sources in Yunnan Province

基于2007年第一次全省农业种植业肥料流失普查数据及实测的32种种植模式的肥料流失系数,分析了不同种植作物结构、种植地块坡度、种植方向影响肥料流失的规律,提出云南省农业种植业肥料流失修正系数选取方法。

The fertilizer loss and the loss efficient obtained from the on -site test of 32 types of planting modes based on the first general survey of pollution sources in Yunnan province in 2007 was applied to rectify the loss efficient.The crop structure,the slope of the planting field and the direction of planting were analyzed to disclose the law of fertilizer loss.
