摘要
以浑善达克沙地典型植物黄柳为对象进行研究,测量其生育期蒸腾速率,并对黄柳生长区内的土壤水热进行测量,通过相关分析,确定土壤水热对黄柳蒸腾速率的影响。研究结果表明,黄柳生育期蒸腾速率与相应时间段的土壤含水率呈显著相关,土壤含水率大的时间段,黄柳的蒸腾速率明显增加;不同埋藏深度条件下的土壤温度与黄柳的蒸腾速率相关性较好,土壤含水率和土壤温度对黄柳的蒸腾速率均有影响。
The yellow willow is the typical plant in Hunshandak sand area. By measuring the transpiration rate of yellow willows in the growing period,and the soil temperature and moisture where the yellow willow are growing,the purpose of the research was to make sure that the soil＇s temperature and the moisture have effect on yellow willows＇ transpiration rate. The results showed that the transpiration rate of yellow willows in the growing period and the soil moisture in the appropriate time have an apparently inverse relationship; while under the condition of higher- soil moisture,the yellow willows＇ transpiration rate is apparently higher,and with the different buried depth of the willows,the soil temperature has a good relationship with the yellow willow＇s transpiration rate.
