Abstract

On the observation data of maize under film drip irrigation in different depth of soil temperature and air temperature, analyzed the change status of film mulching and no film mulching field maize at different depths temperature, the study of the dynamic changes of soil temperature in different growth stages, and the effects of irrigation on soil temperature, at the same time for the soil temperature under different weather conditions were compared. The results showed that: (1) in the early stage of the experiment, there are obvious differences film mulching and no film mulching soil temperature, but existed a smaller temperature differential with air temperature; the later period of the experiment, the soil temperature field mulching and no film mulching began to close, the temperature difference is small, but existed a significant difference between air temperature and soil temperature, the maximum temperature difference of 6 . (2) Before irrigation, soil temperature mainly affected by air temperature, with the irrigation time, irrigation affected by soil temperature in the vertical direction, with the moisture infiltration, the temperature of each soil layer decreased gradually, 0~20cm soil layer temperature was positively related to soil depth, temperature values expressed as 5cm>10cm>15cm>20 cm.(3) Before jointing maize soil warming effect is obvious, after jointing warming effect is not obvious, as the soil depth deepened even lower. (4) Different weather conditions on the film corn soil temperature differential impact, characterized by sunny day > cloudy > overcast sky > rainy day.
