摘要
There are two different models of water flow in soil-plant system, i. e. the linear model and the non-linear model.The linear model is based on an analogy with Ohm’s Law. A difference in water potential is analogous to the electrical potential difference, and the flow rate analogous to current intensity. Hydraulic resistance R(constant)is defined by the ratio of water potential difference
