研究了不同土壤干旱条件下刺槐幼苗的水分生理和生长特性。结果表明，随着土壤水分的降低，蒸腾速率、叶片相对含水量、水势、耗水量、水分利用系数降低，叶片水分亏缺增加。通过对刺槐幼苗生长特性和生长速度的分析，提出刺槐幼苗生长的土壤含水量应不低于58.69% θ f。最后，建立了刺槐幼苗生长指标与土壤含水量的回归模型。同时指出了我们研究中存在的一些问题并进行了讨论。
This paper deals with the water physiology and growth characteristics of locust seedling under different soil drought. The results showed that transpiration rate, leaf RWC ,water potential and water-consumption, water use coefficient decreased with soil water decreasing, and leaf WSD increased with soil water decreasing. By analyzing the growth characteristics and velocity of seedling, the soil water content of locust seedling growth should be not lower than 58.69% θ_f. In the end, we got regression models of growth indices of locust seedling with soil water content. Meanwhile, some problems in our studies were pointed out and discussed.
