The invention belongs to the technical field of tobacco product production and processing, in particular to a tobacco leaf harvesting method and the application thereof. The invention provides a method for harvesting tobacco leaves, which is to measure the chlorophyll values of tobacco leaves in tobacco plants and to pick the leaves if the chlorophyll values are from 10.9 to 24. The invention also provides an application of the above tobacco leaf harvesting method in improving the output value of tobacco leaves, increasing the proportion of tobacco leaves, improving the tobacco smoking taste and enhancing the balance of tobacco leaves. In the invention, the chlorophyll content in tobacco leaves were accurately determined, according to the value of chlorophyll is in preset range to decide whether to harvest, without relying on the experience of technical staff, to achieve a precise recovery; at the same time, according to the determination, the technical scheme provided by the invention, can effectively improve the economic traits of Flue-cured tobacco. The invention solves the defects that the harvesting of the tobacco leaves mainly depends on the experience of the technical personnel in the prior art, and the technical defects that the experience value is relatively large and the precise harvesting can not be realized can be realized.

一种烟叶采收方法及其应用
本专利技术属于烟草产品生产加工
,尤其涉及一种烟叶采收方法及其应用。
技术介绍
烟叶,一年生或有限多年生草本,茄科;植株被腺毛,茎高0.7-2米。烟叶叶柄不明显或成翅状柄,圆锥花序顶生,花萼筒状或筒状钟形,花冠漏斗状,末端粉红色;蒴果,种子圆形或宽矩圆形,黄褐色。烟叶原产于南美洲,世界各地有栽培,为烟草工业最主要的原料。叶绿素仪(soilplantanalysisdevelopment,SPAD仪)由日本学者在80年代末研制,利用两个不同波长的光源分别照射植物叶片表面,通过比较穿透叶片的光密度差异而得出叶绿素值(相对比值),能在野外快速、无损地检测作物叶绿素含量,因此前人对SPAD仪测定值(简称SPAD值)与叶绿素、总氮含量之间的关系进行了大量探索,研究证明植物叶片SPAD值与叶绿素含量具有一定的相关性。目前,烟叶采收主要依靠种植技术人员的经验进行采收,对经验值依靠较大,无法实现精准采收,进一步地,不能有效提高烟叶产值、提高烟叶上等烟比例、提升烟叶吸食口感以及提升烟叶平衡性。因此,研发出一种烟叶采收方法及其应用,用于解决现有技术中, ...
