图5. 扩散方程中1、7、13、19天氮浓度随距离的变化趋势。c(t)是养分浓度; c∝是养分初始浓度, 氮的初始浓度为5 μmol·cm-3; r是根表面的距离。
Fig. 5. Changes in nitrogen concentration with distance for 1, 7, 13 and 19 d in diffusion Nye-Tinker- Barber model. c(t) is the nutrient concentration; c∝ is the initial concentration, with a given value of 5 μmol·cm-3 for nitrogen; r is the distance to the root surface.
