为探索施氯量对烤烟生长发育和产质量的影响,选取土壤氯含量背景值较低的烟稻复种区地块施用不同剂量的氯肥,对云烟87不同部位烟叶进行分析研究。结果表明,适量施用氯肥有利于云烟87生长发育,大田生育期延长,同时促进了云烟87农艺性状的提升。当施氯量为14.30 kg/hm^2时,云烟87的大田农艺性状表现最佳,产量、产值、中上等烟比例明显高于对照。增施氯肥可以提高上、中部烟叶质量,当施氯量为17.87 kg/hm^2时,上、中、下部烟叶化学成分与协调性最优。在与本试验地土壤环境和气候相似的烟稻复种区,施用14.30~17.87 kg/hm^2氯肥应能提高烤烟生长发育并改善其产量和质量。

In order to explore the effects of chlorine application on the growth,development,yield and quality of flue-cured tobacco,different doses of chlorine fertilizer were applied in tobacco-rice multiple cropping area with low soil chlorine content and different parts of tobacco leaves of Yunyan 87 were analyzed.The results showed that proper application of chloride fertilizer was beneficial to the growth of tobacco,and prolonged the growth period and improved the agronomic characters.When treated with 14.30 kg/hm^2 Chlorine fertilizer,the agronomic characters were the best,the yield,output and pro...
