摘要
采用田间小区试验,对烤烟植株体内K、Zn、Mg的交互作用进行研究。结果表明:当K肥、Zn肥、Mg肥配施时,均能显著提高烟叶的K、Zn、Mg含量。K对Zn存在协同作用,但当Mg含量过高时,K对Mg存在拮抗作用。当烤烟叶片的K、Zn、Mg含量比例为300∶35∶100时,烤烟产量和中上等烟的比例较高,分别达到2 663.14 kg/hm2和78.36%。
The interaction among K, Zn and Mg in tobacco plant was studied using field plot test. The results indicated that the combined application of K fertilizer, Zn fertilizer and Mg fertilizer all can improve contents of K, Zn and Mg in tobacco leaf. K and Zn bad synergy effect, but when Mg content is too high, K and Mg had antagonistic action.＇ When the ratio of K, Zn and Mg in tobacco leaf was 300：35：100, tobacco yield and proportion of superior tobacco was relatively high by 2 663.14 kg/hm2 and 78.136%, respectively.
