In this paper, based on the experimental data of maize, sunflower, Acacia confusa and Leucaena glauca under various treatments of air and soil temperature as well as soil water content, the effects of soil water content and temperature on plant root hydraulic conductivity (L R) were analyzed. The results indicate that L R in 40/30℃ (day/night air temperature) was larger than that of 30/25℃ air temperature when soil moisture was suitable for plant growth. When root water stress was very serious, i...
