1、在烟叶适熟期采收基28品种的叶数较少,要想在优质的前提下获得高产,应将有商品价值的烟叶全部采收,片叶不丢.适熟叶的重量比同样大小的未熟叶或过熟叶高10%左右时,易烘烤,商品等级高.适熟叶的一般特征是:烟叶由浓绿转变成黄绿色,茸毛脱落,叶脉乳白色,易折断,茎叶之间角度加大.一般下中叶梢见黄绿、叶尖稍稍变黄开始采收为宜,以后逐次提高落黄程度.采到中叶应是整个叶片黄绿色,叶尖及其附近叶边变黄色;采到上中叶,不仅整个叶片黄绿,有的出现黄中带绿的“黄泡”.烟叶未
1, in the tobacco ripening recovery base 28 varieties of leaves less, in order to obtain high-quality premise, should have all the harvest of the commercial value of leaves, leaves do not lose. The suitable leaf weight ratio The same size of unripe leaves or over 10% of the leaf height is high, easy to bake, high grade of products. The general characteristics of suitable leaves are: tobacco from dark green to yellow-green, velvet shedding, veins white, easy to break, stem The angle between the leaves increased.Generally see the middle and lower tip of the yellow-green, the tip slightly yellowing began harvesting is appropriate, and then gradually improve the degree of falling yellow .Central leaves should be the whole leaf yellow-green, tip and its adjacent leaf edge Turn yellow; to the middle of the leaves, not only the entire leaves yellow-green, and some appear yellow with green “yellow bubble.” Tobacco leaves
