第一讲烤烟育苗烤烟种子很小(每克种子有一万粒左右),且有喜温特性,需要育苗移栽,而且育苗要求有精细的技术。在栽培上通常将烟草生育过程分为苗期和大田期,苗期要占整个生育期的三分之一到二分之一(长短根据育苗期间的条件和措施决定)。苗期即是指烟草在苗床中生长的时期。没有苗,就没有大田栽培,培育出足够数量的烟苗,是保证完成生产任务的先决条件。同时,烟苗的好坏与烤烟的品质、产量有着密切的联系,农谚说:
First, flue-cured tobacco seedling flue-cured tobacco seed is very small (about ten thousand per gram of seeds), and has the characteristics of the temperature of the West, the need for transplanting seedlings, and nursery requires sophisticated techniques. In the cultivation, the process of tobacco growth is usually divided into the seedling stage and the field stage, and the seedling stage should account for one third to one half of the whole growth stage (the length depends on the conditions and measures during the seedling raising period). Seedling refers to the period of tobacco growth in the seedbed. No seedlings, there is no field cultivation, nurturing a sufficient number of tobacco seedlings, is to ensure that the completion of production tasks preconditions. At the same time, the quality of tobacco and flue-cured tobacco quality, production has a close relationship, said:
