摘要 为明确不同光质条件对初烤烟叶物理特性的影响,采用红色、黄色、绿色、蓝色、白色等不同颜色滤光膜创造不同光质条件,以‘K326’为供试材料,研究了不同光质条件下初烤烟叶物理特性的差异。结果表明:(1)覆盖不同颜色滤光膜可明显改变太阳光谱中可见光不同波段的组成比例。(2)同对照相比,覆盖白色薄膜可明显提高烟叶叶面积、单叶重、叶面密度和平衡含水率等,同时降低其含梗率;增加绿光和蓝光比例有利于烟草叶片厚度、拉力、叶面密度和平衡含水率的增加,显著减少叶面积、单叶重、含梗率和填充值等物理特性;增加红光比例则可以降低中上部烟叶的厚度、叶面积、单叶重、含梗率、叶面密度和平衡含水率等。因此,在烟叶生产中可采用覆盖白色透明薄膜来提高优质烟叶水平。 The aim was to confirm the effect of different light qualities on the physical characteristics of flue-curedtobacco. Different light qualities were obtained with different color films of red, yellow, green, blue and white.‘K326'was used as material, and the physical characteristic differences of flue-cured tobacco were studiedwith different light qualities. The results showed that:(1) covering with different colored plastic film couldobviously change the composition proportion of visible light wave bands in solar spectrum;(2) compared withthe control, the leaf area, single leaf weight, density and water proportion of leaves covered with white filter filmincreased significantly, and stalk proportion decreased significantly; by adding green and blue light proportion,the thickness, pull value, density and water proportion of tobacco leaves increased significantly, and the leafarea, single leaf weight, stalk proportion and filling value showed an opposite trend; by increasing red lightproportion, the thickness, leaf area, single leaf weigh, stalk proportion, density, and water proportion of middleand upper leaves reduced. Therefore, covering with white filter film could be used in production to improve thetobacco quality.
