Abstract

The canopy temperatures of rice were observed by the infrared temperature measuring equipment under different irrigation conditions in this experiment, and also it applied the CWSI empirical model and theoretical model to measure whether the crop were suffered from water stress or not. Meanwhile, in this paper, it gave a compare of these two models on the effect of monitoring rice water stress. The result showed that under non-ideal condition, the CWSI value of the empirical model was very volatile and often overflowed the range of 0-1, however, the theoretical model was relatively stable. So it concluded that the CWSI theoretical model was much suitable for the application on monitoring the rice water stress. The results showed that the theoretical model has a good relation with the above indexes, and it can reflect the characteristics of the crop water stress. In addition, some practical experience and viewpoints were given in this paper.
