| 摘 要： | [目的]研究不同打顶时期对烤烟NC297生长、产量及品质的影响。[方法]采用大田试验。[结果]随着打顶时间的推迟,烟株的株高和节距呈逐渐增加的趋势,茎围呈先增后减的趋势,而对上、中、下部位叶片大小的影响较小。现蕾打顶和盛花打顶均对烟叶的外观质量产生不利影响。随着打顶时间的推迟,均价和上等烟比例呈增加趋势,但是产量逐渐下降,产值和中等烟比例先增后减。以第1朵中心花开放打顶的化学成分协调性较好。[结论]NC297以第1朵中心花开放打顶为最佳。

| Abstract: | [Objective] The research aimed to study the effects of different topping stages on the Agronomic Characters,leaf yield and quality of flue-cured tobacco NC297.[Method] Field experiment was used.[Result] The results showed that the plant height and the length of internodes of the variety were increased gradually with the postponed topping stage,while the girth growth was first increased and then decreased.The size of upper,middle and lower leaves was affected slightly by topping stage.Topping at budding stag... |
