| 摘 要： | 采用大田试验研究了苹果酸灌根对烟草生长发育、生理特性和干物质积累产生的影响。在烤烟移栽20 d后用4.5 g/L的苹果酸溶液灌根,每株1 L。结果表明,苹果酸处理促进了烟草的生长发育和干物质的积累,增加了叶片叶绿素含量和下部叶的重量,降低了中部叶和上部叶的重量,缩小了叶片部位之间的差异,增加了产量和产值,提高了均价和上等烟比例。 |

| Abstract: | The effects of malic acid on the growth and development,physiological properties,dry matter accumulation of flue-cured tobacco were studied in field trials.One liter of 4.5 g/L malic acid solution was applied by the root-pouring method to each tobacco plant on the 20th day after transplanting.The results showed that malic acid application was helpful to the growth,development and dry matter accumulation of flue-cured tobacco,it increased the chlorophyll content in leaves,enhanced the weight of the lower lea... |
