辽宁省烤烟品种改革以来,实行了规范化生产,推广了良种良法配套技术,使烟叶质量仃了一定程度的提高。但与国内外先进水平相比仍有较大差距,例如单产尚未达到适产指标。从全省范围看,多数烟田仍因施肥不足而导致烟株营养不良、发育不健、成熟不够,使烟叶小而薄,烟碱含量低,叶色淡而香吃味差;但也有少数烟农盲目过量施肥或氮磷钾比例严重失调而降低品质。因此,如何根据辽宁省不同烟区的土壤生态环境、不同烤烟品种的特性进
Since the reform of flue-cured tobacco varieties in Liaoning Province, standardized production has been implemented and popularized good-quality and good-quality supporting technologies have been improved so that the quality of tobacco leaves is improved to a certain extent. However, there is still a big gap compared with the advanced level both at home and abroad. For example, the yield has not yet reached the appropriate index of production. From the perspective of the province, the majority of tobacco fields are still poorly fertilized due to malnutrition caused by tobacco plants, poorly developed, not mature enough to make the tobacco thin and thin, low nicotine content, leaf color light and poor taste; but there are a few Tobacco farmers blindly excessive fertilization or a serious imbalance of N, P and K to reduce quality. Therefore, according to the characteristics of soil ecological environment and different flue-cured tobacco varieties in different tobacco-growing areas of Liaoning Province
