摘要
为水溶性叶面钾肥在烤烟施肥上的应用提供参考,分析喷施叶面钾肥的烤后烟叶产量、化学成分和产值变化,比较不同品种(云烟85、云烟105)、不同等级(B2F、C3F)烟叶品质和产值的差异性。结果表明:喷施叶面钾肥烤后烟叶的化学成分可用性指数(CCUI)提升,B2F提升效果高于C3F,云烟105优于云烟85;烟叶中钾离子、总糖和还原糖含量均提高;上等烟叶比例提高,产值增收387.6~451.2元/667m^2,增幅超过9.0%;烟叶产量变化不显著。打顶后喷施叶面钾肥对烤烟产量影响较小,能优化烟叶常规化学成分含量,提高烟叶工业可用性。
The differences in quality and output value of cured tobacco leaves from different parts(B2F and C3F)of two flue-cured tobacco varieties(Yunyan 85 and Yunyan 105)are compared by analyzing yield,chemical components and output value of cured B2F and C3F from Yunyan 85 and Yunyan 105 sprayed with water-soluble foliage potassium to provide a reference for application of water-soluble foliage potassium in flue-cured tobacco production.Result:Spraying water-soluble foliage potassium can improve chemical components usability index(CCUI)of cured tobacco leaves,and the CCUI of B2 F and Yunyan 105 is higher than C3F and Yunyan 85 respectively.Spraying water-soluble foliage potassium can increase the content of potassium ion,total sugar and reducing sugar in cured tobacco leaves,proportion of the first-class tobacco leaves and 387.6-451.2 Yuan/667 m^2 with over 9.0%increase rate compared with CK.There is no obvious difference in tobacco yield between spraying foliage potassium treatment and CK.Spraying water-soluble foliage potassium after topping has no obvious influence on tobacco yield and optimizes conventional chemical components content of cured tobacco leaves to improve industrial usability of cured tobacco leaves.
