烟叶的成熟度,是获得优质烟叶最重要的可能因素之一。成熟的烟叶,在叶组织、叶大小、厚度、颜色和叶面“起皱”等方面具有某些特征。这些特征通常可以在有利的生长季节,从播种开始,采取行之有效的栽培措施,就可以从烟株上获得。为了弄清和描述成熟度,必须从烟株上的每一片叶是怎样生长的说起。烟株上的每片叶子处在不同的生长阶段。只因如此,所以每次只能采收2、3片或4片叶。逐叶采收时,生产者只采成熟的烟叶。如果生产者不明白烟叶成熟的机制和过程。也会根据既有的经验识别成熟度。为了描述和解释烟叶的生长和成熟过程,请参考图1。(图略)
The maturity of tobacco is one of the most important possible factors for obtaining good quality tobacco. Mature tobacco leaves have certain characteristics in terms of leaf tissue, leaf size, thickness, color, and “wrinkling” of the foliage. These traits can usually be obtained from tobacco plants in favorable growing seasons, beginning with sowing and using proven cultivation practices. In order to understand and describe the maturity, we must start from the leaf of each leaf is how to grow. Each leaf on the tobacco plant is at a different stage of growth. Because of this, only one or two or four leaves can be harvested at a time. By leaf harvest, the producer only harvest ripe tobacco. If producers do not understand the mechanism and process of tobacco maturity. It also recognizes maturity based on established experience. To describe and explain the growth and maturation of tobacco, please refer to Figure 1. (Figure omitted)
