| 摘 要： | 2008年8-9月,在滴灌技术条件下,利用包裹式茎流仪监测了核桃树的液流量,并用Watchdog自动气象站和土壤水分观测仪对气象因素和土壤水分进行同步观测.结果表明:核桃树的液流速率日变化曲线呈单峰,随着太阳辐射的增强液流速率上升,液流速率达到最大值的时间比太阳辐射达到最强的时间要早1～2h.液流速率与冠层风速、大气温... |

| Abstract: | From August to September 2008,Dynagamax was used to monitor sap flow of walnut trees,under the conditions of drip irrigation technique.Meanwhile,Watchdog Automatic Weather Station and TRIME-IPH were used to measure meteorology factors and soil water content.The results showed that,daily variation regularity of sap flow is expressed in a single peak curve.Sap flow velocity increases with solar radiation intensifying.The time of sap flow velocity of highest value is 1-2 hours earlier than that of solar radiat... |
