不同施钼技术对烤烟生长和质量的影响

Effects of Different Applications of Molybdenum on Growth,Yield and Quality of Flue-cured Tobacco

在长顺烟区采用多点田间试验,研究不同施钼量和不同施钼方式对烤烟叶片大小、经济性状和常规化学成分等的影响。结果表明:施钼能增加叶片大小,提高产量,增加产值,明显减少杂色烟比例;施钼增加了烟叶含钾量,降低烟碱含量;叶面喷施或浇施与叶面喷施相结合的效果明显好于移栽时一次性浇施。

To test the effects of different doses and fertilizer regimes of molybdenum on leaf size , economic characters and conventional chemical composition of flue-cured tobacco , field experiments were conducted in Changshun area .The results showed that the molybdenum could increase the the blade size ,yield and production of tobacco ,and reduce the proportion of variegated tobacco significantly ;and molybdenum fertilization could increase the content of the potassium and reduce the content of the nicotine within tobacco leaves . The effect of foliar spraying on the leaves or combination of watering the root and spraying were much better than that of watering root once when transplanting .
