我国目前每年的烟草种植面积为二千多万亩,烟叶年产量4.5万担;均排世界第一位。但近年在烟叶品质上有下降的趋势,造成这种情况因素是多方面的,但最主要的一点是:烟农没有从根本上解决在种植生产过程中避免大量使用高毒、高残留的化肥、农药等问题,部分烟农也不知如何进行栽培管理。那么怎样合理使用化肥、农药,才能生产出高产高质的烟叶呢?要真正解决这一问题,除了提高正常栽培管理水平外,还要在施肥、用药上做文章,一方面有效减少高毒、高残留化学物品的使用,另一方面是增加对高效、低毒、无残留农药的使用。提高用药水平,只有这样,才能达到
At present, China’s annual tobacco planting area is more than 20 million mu and the annual output of tobacco leaves is 45,000. Both rank the first in the world. In recent years, however, there has been a downward trend in the quality of tobacco leaf, resulting in many factors in this situation. However, the most important point is that tobacco farmers have not fundamentally solved the problem of avoiding large-scale use of highly toxic and high-residue chemical fertilizers during their production. Pesticides and other issues, some farmers do not know how to carry out cultivation and management. So how to make rational use of chemical fertilizers and pesticides to produce high-yield and high-quality tobacco? To really solve this problem, in addition to raising the level of normal cultivation and management, but also in the fertilization, medication to make an issue, on the one hand effectively reduce the highly toxic, The use of high-residue chemicals, on the other hand, adds to the use of highly efficient, low-toxic, residue-free pesticides. Improve the level of medication, the only way to achieve
