烟草单叶重作为烟草产量构成因素之一和烟叶质量有关的标志,已为人们所重视。近年来我国烟叶质量下降,单叶重也作为一个表现特征被提出来。过去,国内的工作,多集中在单株叶重和单位土地面积上叶重的研究,对单片叶的研究则多集中在叶片的面积的增长过程上。单叶重量的形成过程则未见报导。本研究的目的,在于根据单叶重的构成因素不同时期的变化,研究单叶重的形成过程,以为提高和控制单叶重提供依据。 Tobacco single leaf weight as tobacco production and tobacco quality as one of the factors related to the quality of the signs has been valued. In recent years, the quality of China’s tobacco leaves decreased, single leaf weight is also presented as a performance characteristics. In the past, the work in China focused more on leaf weight per unit leaf area and leaf weight per unit of land area. Studies on monolithic leaves focused more on the growth of leaf area. Single leaf weight of the formation process has not been reported. The purpose of this study is to study the formation process of single leaf weight according to the changes of single leaf weight at different periods, in order to provide the basis for the improvement and control of single leaf weight.
