摘  要:
利用热脉冲技术监测梨枣树茎液流,同步利用自动气象站监测的气象资料,研究梨枣树在不同水分处理下的茎液流变化规律及其对不同环境因子的响应,结果表明,各因子相关次序:在晴天,土壤水分>日最高温度>日平均温度>太阳净辐射强度;而在阴天:日最高温度>日平均温度>土壤水分>太阳净辐射强度;多元线性回归分析,确定出茎液流流量与各环境因子间达到显著水平。

摘  要:
The Thermal Dissipation Probe(TDP) was used in this experiment to monitor the dynamics of trunk sap flow,and an Automatic Weather Station was synchronously applied to measure the weather data.The change rule of trunk sap flow and its response to different environmental factors on the different water treatment were studied.The results show: The relation sequence of each environmental factor was that: in fine day,the soil moisture>the daily highest temperature>the daily average temperature>the sun radiant indensity;but in cloudy day: the daily highest temperature>the daily average temperature>the soil moisture >the sun radiant indensity: the SPSS multi-lineaity regression analyse was used,the regression equation between the trunk sap flow and each environmental factor was decided,the equation shows it reaches the significant level.
