施肥是烤烟栽培的重要技术环节,由于烟田土壤养分含量及其释放状况很少能和烟株的吸肥规律相一致,所以要通过施肥来调节。在氮、磷、钾三要素中,磷钾肥用量过多,一般对烟叶品质无不良影响,而氮素却不同,由此可见,在烤烟施肥上主要是氮素肥料的施 Fertilization is an important technical aspect of flue-cured tobacco cultivation. Due to the fact that the soil nutrient content and its release status in tobacco fields are seldom consistent with that of tobacco plants, fertilization is necessary. In the three elements of nitrogen, phosphorus and potassium, the excessive use of phosphorus and potassium fertilizer, generally no adverse effects on the quality of tobacco, but the nitrogen is different, we can see that the main fertilizer on the flue-cured tobacco is the application of nitrogen fertilizer
