| 摘 要： | 用快速称重法测定了宁夏盐池沙地旱生灌木园内中间锦鸡儿和油蒿在生长季的蒸腾速率,同时测定了同时期环境因子的变化规律.结果表明中间锦鸡儿的蒸腾速率日变化呈单峰曲线形式,油蒿的蒸腾速率日变化则呈双峰曲线形式.中间锦鸡儿和油蒿有着适应干旱生境的水分生理特征,但避旱的具体方式不同,中间锦鸡儿属于低蒸腾植物,油蒿属于高蒸腾植物.随着温度的增加,两种植物的蒸腾速率都有增加的趋势.土壤含水量的不同影响油蒿蒸腾速率的高低,而中间锦鸡儿则相对保持自身稳定的蒸腾规律.

| Abstract: | The transpiration rates of Caragana intermedia and Artemisia ordosica grown on Sandy Land Xerophyte Botanical Garden in Yanchi County of Ningxia,as well as the change regularity of environmental factors, were measured.The results showed the diurnal transpiration rate of C.intermedia followed a single apex curve,while that of A.ordosica followed a double apices curve.Both plants possessed the physiological characteristics adapted to the arid zone.But their approaches to resist the aridity were different.A.ordosica had higher transpiration rate.The air temperature affected the transpiration rates of the two plant species.The water content of soil mainly affected the transpiration rate of A.ordosica. |
