This article analyzed the different soil depth days of temperature change and the diurnal variation in the different water treatments through the pear on the the Bazhou irrigation Experiment Station soil temperature monitoring in different water treatments. The results showed that the temperature in depth of 5 cm layer water, was average 0.2℃ and -0.2℃ and 1.8℃ higher in high, medium and low water treatments, respectively, compared with the control. Ground temperature difference between the value of each treatment with increasing soil depth reduced, the difference peak occurred at 10:00 to 14:00, and the maximum temperature increase was observed in depth of 5 cm surface, the order is the high water, low water > control water, the maximum differences of temperature were 4℃, 3.5℃ and 3℃ and 2℃. Each treatment showed the trend of increase and then decrease at different growth stages, increases in 5—10 cm soil layer in the flowering to fruit set are greater than other periods, each treatment different depth of soil in low water at different growth stages the mean temperature is greater than the other treatments, soil temperatures of high water and control treatments are different at each growth stage, and temperature of control in different soil depth, each treatment at different growth period is minimum, and the relationship between temperature change of the low water treatment at different depths at 8:00 and depth can be fitted by the exponential function with very high correlation coefficient, the analysis showed that the warming effect of the low-water treatment is the most obvious.
