摘要
从植物生理上讲,干旱时植株体液理化性质发生改变,体液增浓,叶水势增大,必然在生理电特性上有所反映。为此,从植物生理电特性方面入手,研究了植物叶片含水率及水势的差异,以及干旱对植物生理参数和电参数的影响。植物电信息的研究将对研制植物旱情诊断仪器以及指导节水灌溉具有重要的指导意义。
Physiologically, drought declines water volume in plants＇ bodies which caused the cnemlcal cnange of the body liquid, the body liquid is thicker and the flow of water is larger. And all of this would be reflected on the electric character of plants. Thus this researching on plant electric information plays an instructive role in seeking methods to test plant water and instructing the irrigation. Adopting the undamaged contact test method, the author decides the range and testing condition in testing electrical characteristic of plants. Based on this study, the author studies the distinction of the water rate and the flow of water of plant leaves. Furthermore, the author studies the influence of drought on electrical properties and relationships between electrical properties and physiological chemistry properties. This research on plant electric information will be instructive to develop the testing instruments on plants＇ drought condition and facilities of water conserving.
