Study on Temperature and Humidity Changing Law of Korla Fragrant Pear in the Growing Season
The aim of this paper was to study the temperature and humidity change law in the crown of Korla fragrant pear and provide theoretical basis for culturing reasonable structure.The EI-USB-2[1].0 Temperature and Humidity Recorder was used to measure the diurnal and season variation of temperature and humidity in the different parts of Korla fragrant pear canopy.The results showed that the temperature on upper level in the eanopy was higher than that on lower level.The greatest difference in temperature in different parts was 9.5 ℃,the average temperature was gradually increased from Mar.to Jul.,then it begins to decrease.The temperature on upper level was higher than that on lower level ;The relative humidity in canopy lower level was higher than that on upper level,the humidity was gradually increased from inside to outside and humidity on upper level was gradually decreased.The greatest difference of relaltive humidity in different parts was 18.6％.The average relative humidity was gradually decreased from March to July,then gradually increased;The difference between temperature and relative humidity of the vertical position was greater than that of the horizontal one.There was significant difference between the temperature in canopy and relative humidity produced by the difference between quantity of leaf and branch and canopy structure.And the difference on sunny days was greater than that on cloudy days.The change of structure about leaf and branch in the canopy can regulate the temperature and humidity in the canopy.
