| 摘 要： | 为确定烟草的适度亏水效应及烟草水分生理灌溉指标,进行了烟草蒸渗仪试验,通过控制土壤水分下限研究烟草的适度亏水效应.试验结果表明:烟草光合作用受土壤水分影响较大,当旺长期土壤含水量控制下限为田间持水量的75%时,光合作用最强;细胞液浓度的变化受土壤含水量影响亦较大.

| Abstract: | Experimental study was performed to determine the moderate water deficit effect and physiological irrigation index of tobacco with lysimeters by controlling the lower limit of soil water content.The result indicates that photosynthesis and the cell liquid density of tobacco are both seriously influenced by soil water content,and that photosynthesis is the most vigorous when the lower limit of soil water content is 75 % of water holding capacity of farmland during the vigorous growing period of tobacco. |

| Keywords: | tobacco physiological irrigation index water deficit effect |
