The K supplied by diffusion occupied>90% that uptaken by the plants at seedling stage, however,it could decrease to 70% at growing peak of wheat plants in soils of a high noisture, suggesting a comparatively significant role sometimes played by mass flow in supplying K to crops.

As a main consuming way of phreatic water in arid land, phreatic evaporation is the key factors that cause water resources deficiency and soil salinization. It is very important that research on phreatic evaporation and calculation method to evaluate groundwater resources, improve saline sodic soils and plan the irrigation and drainage system. In view of the actual question that the AB formula, exponential type formula and power type formula will highly estimate the content of phreatic evaporation when the atmospheric evaporation is tending to much larger. Based on the principle of soil water dynamics, the relationship between the density of phreatic evaporation and atmospheric evaporation under different phreatic water depth is analyzed in this paper. The conception of critical atmospheric evaporation is presented and the method of sectioned curve fitting for phreatic evaporation is also put forward.By the case study,it is showed that the method of sectioned curve fitting can effectively solve these questions above mentioned.
