摘　　要：矿质营养元素对烟草品质的影响尤为重要,能改善烟草生产不同时期氮、磷、钾在叶片中的累积量,改变烟草的燃烧、色泽、弹性、味道、填充力等性能。分析了烟草对氮、磷、钾、氯4种矿质营养元素的需求,提出了影响烟草生产中产量和品质的原因以及制定大田生产优质烟草的施肥方法和氮、磷、钾的配合比例。Mineral nutrients have the effects on tobacco quality by improving nitrogen, phosphorus, potassium and chlorine accumulation in tobacco leaves at the different growth period. The paper puts forward the reasons affecting tobacco yield and quality, application methods for producing quality tobacco and proper ratio of N,P and K fertilizer based on analyzing the needs of nitrogen, phosphorus, potassium and chlorine at tobacco different growth periods.
