摘要
[目的]为指导烤烟合理施肥,提高烟叶品质提供科学依据。[方法]通过田间小区试验,对烤烟植株体内K、Zn、B的交互作用进行研究。[结果]K肥、Zn肥、B肥配施能显著提高烟叶的K含量,降低烟叶烟碱含量,糖碱比和施木克值处于较合理的范围,烟叶内部化学成份趋于协调。[结论]当烤烟叶片的K、Zn、B含量比例为300∶30∶15时,烟株根系发达,干物质积累量大,烤烟产量和中上等烟的比例较高,分别达到2 701.21 kg/hm2、81.21%。
[ Objective ] The research aimed to provide the scientific basis for the guidance of the reasonable fertilization and the improvement of the leaf quality. [ Method] Using field plot test,the interaction of boron ,K and zinc in the body was studied. [ Result] The combination of K fer- tilizer, zinc fertilizer and boron fertilizer could significantly increase the content of K. The lower the content of nicotine, the sugar alkali ratio and ShiMuKe value were in a more reasonable range. Internal chemical composition in tobacco leaf tended to be coordinated. [ Conclusion] The root development of tobacco plant and dry matter accumulation was higher, the proportion of superior tobacco in tobacco production was a higher pro- portion up to 2 701.21 kg/hm2, 81.21% with the ratio of K, zinc and B content in flue -cured tobacco leaf was 300： 30： 15.
