不同间作方式对烤烟生长及烟叶重金属含量的影响

目的]找出行之有效的利用不同间作方式控制烤烟重金属含量的栽培措施方法。方法]采用不同的间作方式处理,调查研究烤烟生长期间生物学特性和采烤后土壤及烟叶中的重金属含量。结果]大田间作试验发现,不同间作处理对烟株生长有促进作用,间作青豆的处理,效果更加明显。在保证烟株旺盛生长的同时,间作对于土壤和烟叶中部分重金属含量的影响差异显著。结论]在生产中进行适当间作,对于烤烟生长和降低烟叶重金属含量具有一定的实际意义。

Effects of Tobacco’s Growth and Heavy Metal Content in Flue-cured Tobacco by Different Intercropping Ways

Objective] The aim was to find out an effective intercropping method to control heavy metal content of flue-cured tobacco.Meth-od] By using different intercropping methods, biological characteristics during flue-cured tobacco growth period and heavy metal content in soil and tobacco after harvest were investigated.Result] Different intercropping treatments had promoting effects on tobacco growth, intercropping green beans had more obvious effect.At the same time of ensuring tobacco plant growth, effects of intercropping treatments on heavy metal con-tent in soil and tobacco leaf had significant differences. Conclusion] Proper intercropping in production has a certain practical significance on flue-cured tobacco growth and heavy metal content reduction.
