| 摘 要： | 研究了不同土壤水分条件下甜菜叶片的ＣＯ２ 和Ｈ２Ｏ 汽交换变化动态情况． 结果表明，水分处理的甜菜叶片的光合速率和蒸腾速率较之对照高，说明土壤湿度过大不是甜菜生长的最适条件，轻度适宜的土壤水分亏缺将有利于甜菜的生长．

| Abstract: | The dynamic changes of gas exchange of sugarbeet leave is studi.The results show that photosynthetic rate and transpiration rate of sugarbeet leave under conditions of different water stress are higher than that of control. The conditions of too much moisture in the soil is not best for the most suitable growth of sugarbeet, while the condition of light water stress will be benefit for the growth of sugarbeet. |
