摘要
通过油菜(十字花科)和黑麦草(禾本科)两种绿肥肥料用量的小区试验,以研究绿肥压青对烤烟光合特性的影响。结果表明:在烟苗移栽前土地施用绿肥,可以提高移栽后烟苗的叶绿素含量,气孔导度和蒸腾速率,净光合速率也略有提高,同时可以不同程度改善烟苗移栽后不同时期的水分利用率和气孔限制值。
The plot experiment was conducted to study the effect of green manure dressing on physiological characteristics of flue-cured tobacco leaves.The results showed that the green manure that was applied before tobacco seedling transplanting could increase the chlorophyll content,stomatal conductance,transpiration rate and net photosynthetic rate and could different degree improve the water use efficiency and stomatal limitation in different periods after transplanting tobacco seedlings.
