摘要
[目的]研究沼液对烤烟农艺性状、病虫害和产质量的影响.[方法]采用小区试验,在烤烟苗期和大田期,采用叶面喷施和灌根2种方式施用沼液,研究沼液对烟叶生物学性状、农艺性状、病虫害和产质量的影响.[结果]沼液处理烟苗的茎高、茎围、长势明显优于对照处理,灌根处理的效果稍优于叶面喷湿;沼液处理的株高、叶片数、叶面积等均高于对照处理,叶面喷施的株高、叶片数、叶面积等优于灌根;沼液处理对马铃薯Y病毒病、角斑病、气候性斑点病的防治效果均优于对照,而对黑胫病无明显防治效果,叶面喷湿对病害的防治效果优于灌根处理;在产量与产值方面,沼液处理优于对照,叶面喷施处理优于灌根处理.[结论]沼液对促进烤烟生长和提高产质量效果较好,且采用叶面喷施的效果优于灌根.
Abstract
[Objective] To research the effects of biogas slurry on agronomic traits,yield and output value of flue-cured tobacco.[Method] Plot test was adopted.Foliage spray and root irrigation were used to apply biogas slurry.We researched the effects of biogas slurry on the biological character,growth period,agronomic characters,plant diseases and insect pests,yield and output value of flue-cured tobacco leaves.[Result] The stem height,stem girth and growth vigour of tobacco seedlings treated by biogas slurry were superior to those treated by common fertilizer.Root irrigation treatment was slightly superior to leaf area spraying.Plant height,leaf number and leaf area of biogas slurry treatment were higher than those of control treatment;and leaf area spraying was superior to root irrigation treatment in plant height,leaf number and leaf area.Control effects of biogas slurry treatment on tomato virus Y,angular leaf spot and climate scab were all higher than those of control.However,biogas slurry treatment showed no significant control effects on black shank;and leaf area spraying was superior to root irrigation treatment.In the aspects of yield and output value,biogas slurry treatment was superior to root irrigation treatment.[Conclusion] Biogas slurry has relatively good promotion effects on the growth of flue-cured tobacco and its quality improvement.And leaf area spraying is superior to root irrigation treatment.
