胡杨树干液流与树干生物电特性的关联规律研究

Short of water resource is the reason populus diversifolia ebb, study on getparms equipment of moisture physiological index, providing technical support for populus diversifolia protection and rehabilitation. Populus diversifolia trunk liquid flow is the token of populus diversifolia moisture, trunk bioelectrical index is easy to inspect, and easy to influenced by trunk moisture. Through survey on the spot trunk liquid flow and bioelectrical index, build the relationship of them. Trunk liquid flow and bioelectrical index shows periodic change of unimodal curve, negative relationship, and distinct to different growing period and season, summer and autumn changes more than spring, young populus diversifolia's trunk liquid flow and bioelectrical index are more than old populus diversifolia. In regression analysis, polynomial relationship can be expected, coefficient of regression are high in young populus diversifolia and low in old(correlation coefficient:0.7664/0.4361). In general, only using trunk liquid flow information explaining bioelectrical index is not complete, environment should be included. The result provides theoretical support for exploitation populus diversifolia wireless detection equipment of moisture physiological index.
