烟秆是烟株生长发育过程中不可缺少的部分,起到支持烟株,着生叶片,输送养分和水分的作用。但它毕竟是烟叶生产过程中的副产品,本身不会带来直接的经济效益;相反,从烟叶收获完到霜冻之前,烟秆及烟芽等还要从土壤中吸取养分,造成无益的损耗。目前,我省大部分烟区仍是等到来年春天才拔烟秆,只有少数秋翻地地区才在秋天拔掉烟秆,这样就浪费了土壤肥力,给农业生产造成了不应有的损失。我们可以算一笔细帐,仅以我省烟叶重点生产县(市)敦化市来讲,烤烟晒烟面积近6000公顷,按每公顷18000株计算,每株烟按积
Tobacco stalks tobacco plant growth and development is an indispensable part of the process, play a supporting tobacco plant, with leaves, transport nutrients and water role. However, it is, after all, a by-product of the tobacco production process, which in itself will not bring direct economic benefits. On the contrary, before the tobacco leaves are harvested, the tobacco stalks, tobacco buds and the like also draw nutrients from the soil, resulting in unwanted loss. At present, most of the tobacco-producing areas in our province still wait till the spring of next year to pull tobacco stalks. Only a small number of autumn-fall areas pull tobacco stalks in the autumn, thus wasting soil fertility and causing undue losses to agricultural production. We can count a fine account, focusing on the production of tobacco in our county (city) Dunhua City, the area of nearly 6,000 hectares of tobacco cured tobacco, 18,000 plants per hectare, per plant plot
