摘 要:为了探讨不同钾肥施用时间对有机生态烟产质量的影响效果,通过田间对比试验,研究了不施钾肥(K0)、栽后30 d施钾(K1)、栽后45 d施钾(K2)对生态烟产质量的影响。结果表明,追施硫酸钾,能显著提高生态烟产质量及钾含量,有利于烟叶叶片开片及评吸质量的改善;就施钾时间而言,栽后30 d追施钾肥对烟叶开片效果最好、产量及产值最高、常规化学成分最协调、评吸效果最佳。综合分析可得,在黔西南兴义烟区,栽后30 d内每公顷施用不少于240 kg硫酸钾,能有效提高生态烟产质量。In order to study the effects of different potassium application periods on the yield and quality of ecological tobac-co by field comparative experiment, no potash fertilizer(K0), 30 days after transplanting for potash fertilizer (K1), 45 days after transplanting for potash fertilizer (K2) were set up. The results showed that potassium application could significantly im-prove the yield and quality, potassium content, leaves-enlarging and smoking quality of ecological tobacco, and the treatment of K1 had the best leaves-enlarging, the highest yield and value, the most coordinated conventional chemical compositions and the optimal smoking quality. According to comprehensive analysis, potassium application amount in 240 kg∕hm2 at 30 days after transplanting was conducive to improve the yield and quality of ecological tobacco.
