【 摘 要 】

The experimental results show that the infrared thermal imaging can observe the overall temperature distribution of canopy in rice much more intuitively. The canopy temperature of different soil water potentials in the field showed a regular change, and the rice canopy reached the highest temperature at 13:00-15:00, and the lowest at 2:00-4:00. The range of temperature difference between the crown and the air is gradually increased with the prolongation of the water stress. And the best effect of water stress to observe was at 13:00-15:00 through canopy temperature.
