摘要
[目的]为改善上部烟叶的质量提供理论依据。[方法]以烤烟品种G80烟株上部5片叶为材料,研究3种不同采收方式(Ⅰ:不带茎一次性采收;Ⅱ:一次性带茎砍收;CK:普通采烤)对烟叶质量和经济效益的影响。[结果]一次性不带茎采收和带茎采收后烘烤烟叶的外观质量均优于常规采收烟叶,2处理上部5片叶的产值分别较CK提高892.65、107.25元/hm2,均价分别较CK提高1.22、0.55元/kg,单叶重分别较CK降低0.41、0.58 g,烟叶化学成分更趋协调;带茎采收烘烤用工成本高于不带茎一次性采收,综合经济效益低于不带茎一次性采收。[结论]烤烟G80上部叶的最适宜采收方式为一次性不带茎采收。
[Objective] The purpose was to supply theoretical basis for improving the quality of upper tobacco leaves.[Method] With the 5 upper leaves from the plants of flue-cured tobacco variety G80 as the materials,the effects of 3 different harvesting ways on quality and economic benefit of tobacco leaves were studied.The 3 harvesting ways were harvesting all the leaves and none stem at one time(treatment Ⅰ),harvesting all the leaves and stems by cutting at one time(treatment Ⅱ),common harvesting and flue-curing(CK).[Result] The apparent quality of flue-cured tobacco leaves from treatments Ⅰ and Ⅱ was superior to that of flue-cured tobacco leaves from CK.Compared with CK,the output value and mean prices of 5 upper leaves from the 2 treatments were increased by 892.65 and 107.25 yuan/hm^2,1.22 and 0.55 yuan/kg resp.their single leaf weights were decreased by 0.41 and 0.58 g resp.and their chemical compositions in tobacco leaf were more harmonious.The flue-curing labor cost of treatment Ⅱ was higher and its comprehensive economic benefit was lower than that of treatment Ⅰ.[Conclusion] The optimum harvesting way for upper leaves of flue-cured tobacco G80 was harvesting all the leaves and none stem at one time.
