摘 要:[目的]寻求云南省主栽烤烟品种云烟85的最佳施纯氮量。[方法]在玉溪地区选择肥力较高的田块,设置3种施氮量(施纯N 60、120和180 kg/hm2),研究不同土壤氮水平对烤烟品种云烟85生长、烟叶产质量及工业可用性的影响。[结果]随着施氮量的增加,烟株的长势越好,烟叶产量也呈上升趋势;其产值、上等烟比例,中上等烟比例以施纯氮量为120 kg/hm2的烟叶最好,分别比施纯氮量60和180kg/hm2的处理高出57.0%、41.4%、15.4%和12.9%、20.1%、7.9%;从烟叶的内在化学成分和单体烟叶评吸结果来看,也以该处理的相对最协调。[结论]综合考虑烟叶的经济效益和工业可用性,在该试验条件下,云烟85的最佳施纯氮量为120 kg/hm2。[ Objective] The research aimed to seek the best net N application rate for main planting flue-cured tobacco variety of Yunyan 85 in Yunnan Province. [Method] The field plot with higher fertility in Yuxi region was chosen and 3 kinds of N application rate were set up (net N application of 60, 120 and 180 kg/hm^2) to study the effect of different soil N level on the growth, leaf yield and quality of flue-cured tobacco Yunyan 85 and industrial availability. [ Result] The growth vigor of tobacco plants was getting better with the increase of N application rate, and tobacco yield also showed raising trend, but its output value, the proportion of high and high-middle class leaves were the best ha the treatment with net N application at 120 kg/hm^2, which were 57.0%, 41.4%, 15.4% and 12.9%, 20.1% and 7.9% resp. higher than the treatment with net N application at 60 and 180 kg/hm^2. Considering from the inherent chemical composition of tobacco leaves and smoking results of monomer tobacco, this treatment was most relatively harmonious. [ Conclusion] In comprehensive cousideration of economic benefit and industrial availability of tobacco leaves, the best net N application rate for Yunyan 85 was 120 kg/hm^2 under this test condition.
