摘要
[目的]分析品种多样性对烤烟生产的影响。[方法]烤烟品种K326、云烟87、云烟85和红花大金元间作,以试验当地连片种植的烤烟品种(K326)为对照。[结果]品种多样性能有效防治体系中炭疽病、气候性斑点病,却降低了体系对赤星病、普通花叶病和烟青虫的抵抗能力。与对照相比,品种多样性使烤烟产量和产值分别提高17.81%和10.42%,但使上等烟比例降低10.36%。[结论]该研究可为以后在烟草生产上积极开发、保护和利用生物多样性以提高烟草产、质量提供理论依据。
[Objective] The aim was to analyze the effects of variety diversity on flue-cured tobacco production.[Method] The flue-cured tobacco varieties of K326,Yunyan87,Yunyan85 and HD were intercropped,taking K326 of local contiguous planting as control.[Result] The variety diversity prevented the Colletotricum destructivum and climate spot effectively,while reduced their resistance to brown spot,tobacco mosaic virus （TMV） and hornworm.Comparing to control,the yield and output value of variety diversity increased by 17.81% and 10.42% resp.,while their proportion of high grade leaves decreased reduced by 10.36%.[Conclusion] The study provides a theoretical basis for positive development,protection and utilization of biodiversity to improve yield and quality of tobacco in tobacco production in future.
