驳枝和追施氮肥对早花烤烟不同部位烟叶产量的影响
Effects of Branching-after-topping and Topdressing on the Yield of Different Parts of Early-flowering Flue-cured Tobacco
摘要
Abstract
[Objective] To research the effects of branching-after-topping and topdressing on the yield of different parts of early-flowering flue-cured tobacco.[Method]With tobacco cultivar K326 as the research materials,we researched the effects of branching-after-topping and topdress-ing on the agronomic characters,yield per plant,yield of different parts,proportion of first-class tobacco and average price.[Result] Branching-af-ter-topping and topdressing could augment productivity of flue-cured tobacco;the outputs of central section,lower leaves and upper leaves of the treatments of branching 4 leaves after topping and 15 kg/hm2pure nitrate as topdressing was larger,and the proportions of central section,lower leaves and upper leaves to the entire output of single plant was larger.The measure of branching 4 leaves after topping and 15 kg/hm2pure ni-trates as topdressing for early-flowering tobacco was the best.[Conclusion] This research provided theoretical basis for the actual production.关键词
