摘要
分别从烟草生长发育、生长量和主要经济性状等方面研究6%抗坏血酸水剂对烟草的增产效果。结果表明,该药被烟叶吸收后,参与烟草生理生化全过程,促进烟草生长发育;烟草根系发达、植株变高、茎变粗、光合作用效率增强、叶绿素及抗坏血酸含量增加;上等烟率、橘黄烟率较对照提高20%-30%;改善烟叶的品质,平均增产20%,增收2250-3000元·hm^-2。
The effects of 6% ascorbic acid WA were studied on tobacco growth,yield and main economic charcters. The results showed that the growth of tobacco could be improved after absorbing 6% ascorbic acid WA. Compared with the contrast, the root vigor, plant height, stem diameter, photosynthesis, leaf areas, content of chlorophyll and ascorbic acid tended to be obviously increasing. Moreover superior leaves ratio and yellow leaves ratio increased by 20% -30%. As a result, the average yield increased by 20% and the average benefit was 2250 -3000 Yuan per hm^2. The pesticide could be extended to a large-scale application.
