| 摘 要： | 用快速称重法,测定蒸腾强度。结果表明;蒸腾日变化曲线呈双峰状,最高峰约在中午11-13时出现。用烘干法测定组织含水量,结果表明:根、茎、叶含水量分别为37.54％,48.44％,61.03％。并用小液流法测定根、茎、叶的水势。最后通过测定酸枣的SLA(6.03m~2/kg);估算了酸枣的年蒸腾耗水量

| Abstract: | This paper made a study on the transpiration intensity of Ziziphs jujuha popula- tion. With the method of rapid weighing, the resulf shows that the daily change of transpiration rate has two Peaks. the highest peak is at 11:00--13:00. with the way of dry and warm by the fire the result shows the water contenf of the root, sterm and leave in turn is 37.54%,48.44% and 61.03%.By measured the SLA(6.03m~2/kg), this estimate the transpiration efficiency. |
