| 摘 要： | 研究了土壤不同含水量条件下 ,烤烟品种G80的光合特性。结果表明 ,在旺长期和成熟期前期 ,较高土壤含水量对G80叶片的净光合速率影响较小 ,而较低土壤含水量对叶片的净光合速率影响较大。此期充足的土壤水分有利于提高烟株群体的净光合速率。

| Abstract: | The photosynthetic characteristics of flue|cured tobacco cultivar G80 under the different soil moisture content conditions were studied. The results showed that high soil moisture content had a smaller effect on the net photosynthetic rate of G80 leaves during fast growing and early ripening periods, and low soil moisture had a more significant effect on it. Enough soil water was favorable for increasing the net photosynthetic rate of colonial tobacco plants during these periods. |
