To provide theoretical bases for the defense of apple spring frost,the influences of irrigation in early spring on temperature and humidity of air and soil in apple orchard were analyzed.The results showed that the daily average temperature,average maximum air temperature,heating rate in daytime,daily range of temperature and air temperature at night at 0.5 meter above the ground lowered 2.62℃,3.02℃,29.53%, 3.23℃and 2.32℃ respectively by irrigation compared with control,and the effects could sustain 3 days.The air temperature at night at 1 .5 m and 3.0 m above the ground raised 0.83℃ and 1 .21 ℃ respectively after ir-rigation compared with control,but the effect just sustained 1 day.The relative air humidity of the orchard in-creased by 4.58 percentage points by irrigation compared with control,and the humidifying effect could sus-tain 3 days.The cooling effect of irrigation on 0 ~20 cm depth soil was the most obvious,and the daily average soil temperature decreased 0.90℃ compared with control.The daily maximum soil temperature of 0 ~20,20 ~40 cm and 40 ~60 cm depth soil decreased 1 .33℃,0.27℃ and 0.38℃,the average daily range of soil tempera-ture decreased 0.85℃,0.65℃ and 0.09℃,and the soil temperature at night decreased 1 .62℃,0.09℃ and 0.27℃ respectively compared with control,and the regulating effects of irrigation on temperature and humidity of soil could sustain one week.
