摘　　要：为充分发挥大理州洱海流域冬季蔬菜生产优势,促进农民增收,进一步规范贡菜种植科学减量施肥,有效削减农业面源污染,实现贡菜产业向增效、减排、绿色、健康方向良性发展,通过施用不同氮磷钾配比的肥料,探索实现洱海流域贡菜种植最佳生产效益的科学精准施肥模式。试验结果表明,综合考虑种植成本、生产效益和农业面源污染等因素,确定洱源县洱海流域右所片区最适宜贡菜种植的肥料施用模式为每667 m^(2)施商品有机肥500 kg+N16.7 kg+P_(2)O_(5)7.5 kg+K_2O 7.5 kg。In order to give full play to the advantages of winter vegetable production in Erhai Lake Basin,increase farmers'income,further standardize the scientific reduction and fertilization of tribute vegetable planting,effectively reduce agricultural non-point source pollution,and achieve the development of tribute vegetable industry in the direction of efficiency,less emissions and green and healthy,the scientific and preecision fertilization model of the best production efficiency in the cultivation of tribute vegetable in Erhai Lake Basin was explored by applying fertilizers with different ratios of nitrogen,phosphorus and potassium.The results showed that considering the planting cost,production efficiency and agricultural non-point source pollution,the most suitable fertilizer application mode in the yousuo area of Erhai Lake Basin was commercial organic fertilizer 500 kg+N 16.7 kg+P_(2)O_(5)7.5 kg+K,07.5 kg per 667 m^(2).
