| 摘 要： | 采用大田试验研究了灌水和钾肥用量及其互作对烤烟产量和品质的影响。结果表明，随钾肥用量增加，烟叶产量、产值和上等烟比例都有增大的趋势，灌水和增大钾肥用量都可以不同程度提高烟叶产量、产值和上等烟比例，以施钾的效应较为明显，灌水和施钾对提高烟叶上等烟比例有明显的互作效应。回归分析结果，烤烟产量、产值和上等烟比例的钾肥效应模型均为呈二次曲线，说明在钾肥用量较高时，肥料的增产增质效应趋于降低。从不同钾用量处理烟叶经济性状、化学成分和评吸质量综合分析，湘西烤烟适宜的钾肥用量为240kg/hm2。

| Abstract: | In order to optimizing the management of irrigation and fertilization of flue-cured tobacco in Xiangxi tobacco-growing areas to increase yield and quality of the leaves and improve water and fertilizer use efficiency of the plant, a field experiment was conducted using tobacco （Nicotiana Tobacum L.） cuhivar Yunyan87 grown in split-plot design with three replications in Tobacco Institute of Xiangxi in 2007-2008. The traits associated with the effect of irrigation and potassium rate on yield and quality of flue-cured tobacco were investigated. The results showed that yield, output value and proportion of superior leaves of flue-cured tobacco tended to increase with the increasing of potassium rate. Both irrigation and potassium rate could improve yield, output value and ratio of high class leaves in different degrees, and the effect of potassium rate was more significant than that of irrigation. There was obvious interaction effect of water and potassium coupling on increasing the proportion of superior leaves. In different irrigation conditions, the models of the effect of potassium rate on yield, output value and ratio of high class leaf of flue-cured tobacco were all quadratic curves, which indicated that the effects of potassium on increasing yield and quality of flue-cured tobacco tended to decrease in higher potassium rate. Comparing with different treatments of potassium rate in economic characteristics, chemical components and smoking quality of the leaves, the appropriate potassium rate of flue-cured tobacco in was 240 kg/hm2. |
