田间不适用鲜烟叶的消化时期与消除叶片数对烟叶经济性状的影响

为了明确田间不适用鲜烟叶的最佳消化时期与消除的叶片数,提升优质烟叶原料的有效供给能力。采用正交设计试验设计与直观分析方法,研究了田间不适用鲜烟叶(底叶与顶叶)的不同消化时期与消除叶片数对烤烟经济性状的影响。结果表明:消除上部叶的时机是影响烤烟上等烟比例、中上等烟比例、均价与产值的主要因素,下部叶消除叶片数是影响烤烟产量的主要因素。在试验设置的水平范围内,优化烟叶结构后均不同程度提高了烤烟的经济性状,以处理3组合和处理5组合的烤烟经济性状表现最好。

Effects of Period and Number of Removing the Field Inapplicability and Fresh Leaf on Economic Character of Flue-cured Tobacco

In order to identify the optimum period and number of removing the field inapplicability and fresh leaves, and further optimum tobacco structure and promote the effective supply ability of high quality tobacco. In this paper, the direct-viewing analysis of orthogonal experiment design method was employed to study the influence of different period and number of removing bottom and top leaves on economic character. The results showed that the period of removing the top leaves was the main factor for fine tobacco ratio, high middle tobacco ratio, mean price and output value; the number of removing bottom leaves was the main factor for yield; every treatments improved the economic characters of flue-cured tobacco in some extent and the treat 3 and the treat 5 were the best.
