Abstract: In order to reveal the temperature characteristics of pear tree in field covered by striped cloth, a microclimate observation experiment of the pear trees in and outside the striped cloth shed was conducted in Shanghu Town of Korla from January 7th to March 8th in 2015. The change rules of trunk temperature were analyzed. The results showed that the average temperature and hourly temperature inside the shed were higher than those outside, and the overall temperature trends inside and outside the shed were the same. Under different weather types, the change speed of the temperature in sunny days was the highest, followed by that in cloudy days, and that in overcast days was the lowest, and the change of temperature at night was stable for different weather types. The trunk temperature in the sunny side was higher than that in the shady side, the difference between the sunny side and the shady side ranged from 0.06℃ to 2.59℃ . The hourly trunk temperature of both the sunny side and the shady side were almost similar at night. The change range of the hourly trunk temperature in the sunny side against different weather types was greater than that in the shady side. The lowest trunk temperature in the sunny side outside the shed all appeared at 9:00 under different weather types, and that in the shady side appeared 1 h later, and the highest trunk temperature in the sunny side under sunny weather type appeared at 16:00, and 1 h later under cloudy and overcast weather type, and 2 h later in the shady side.
