前作对烤烟产质量的影响

Effects of Previous Crops on Yield and Quality of Flue-cured Tobacco

[目的]为烤烟轮作提供新模式。[方法]在景谷县开展了前作除虫菊、小麦、冬闲地处理对云烟87产质量的影响的研究。[结果]除虫菊前作能增加云烟87的株高、叶数、茎围、最大叶面积,对花叶病、白粉病、赤星病有较强抗性;其产量、产值、均价、上等烟比例在3个前作处理中最高。小麦前作的中上等烟比例最高,除虫菊次之;其烤后烟叶的身份、油分、色度较好,能改善烤烟的感官品质。[结论]除虫菊前作能提高烤烟产质量。

[Objective] To provide new mode for crop rotation of flue-cured tobacco.[Method] Effects of different previous crops on yield and quality of Yunyan 87 were carried out in Jinggu County,including pyrethrum carneum,wheat and winter idle land treatments.[Result] Pyrethrum carneum could enhance the plant height,leaf number,stem girth and maximum leaf area of Yunyan 87,having relatively strong resistance to mosaic disease,powdery mildew and brown spot. Its yield,output value,average prive and proportion of upper-class tobacco were the highest in the three treatments.The proportion of midium- and upper-class tobacco in wheat treatment was the highest,followed with pyrethrum carneum.The status,oil content and chromaticity of wheat treatment were relatively good,which could enhance the sensory quality of flue-cured tobacco.[Conclusion]Pyrethrum carneum treatment could enhance the yield and quality of flue-cured tobacco.
