摘  要：
对乌兰察布市察右后旗人工造林地土壤含水量及柄扁桃幼苗水分生理特征进行研究。结果表明,由于长期干旱,样地土壤含水量降到7.24%以下,柄扁桃自然含水量为68.41%,束缚水与自由水比值为1.01,其自然饱和亏缺为17.94%。持水力测定表明,柄扁桃持水力曲线斜率大。PV曲线分析表明,Ψπ100和Ψπ0值为7.08 MPa。蒸腾速率日进程变化分析表明,柄扁桃的"午休"现象不很明显。

摘  要：
The soil water content of afforested land and the hydrological physiological characteristics of Amygdalus pedunculata Pall.have been studied in Chayouhou Qi.The results showed that because of long time drought,the soil water content of sampling plot decreased below 7.24%,the ntural water content of Amygdalus pedunculata Pall.was 68.41%,the ratio of bound water and free water was 1.01,the water shortage under natural saturation was 17.94%.The measurement of water holding capacity showed that the water holding capacity curve slope of Amygdalus pedunculata Pall.was large.The analysis on PV curve showed that the value of Ψπ100 and Ψπ0 were 7.08 Mpa.The analysis on transpiration rate diurnal variation showed that midday depression of Amygdalus pedunculata Pall.wasn't obvious.
