Objective: According to the measured data of soil temperature and air temperature in early spring in Kashgar area of Xinjiang, the temperature change characteristic about apricot wheat interplanting and the only wheat monoculture during the 24 h was analyzed. Method: The paper took Saimaiti apricot of 8 years old and Xindong-20 as investigative objects, and carried out a study of phenophase, horizontal distance, soil depth and air temperatures at different levels under the intercrop and monoculture model by ZDR-41. Result: The results showed that: (1) the total changes of soil temperature present the onefold type of "S"; (2) there were differences in the sustained time of temperature extremum under the 20 cm soil layer of different modes. The topmost and lowermost of air temperature did not have sustained time, but it had sustained time of the topmost and lowermost under the different horizontal distance in the intercrop model; (3) in the stages in germination, temperature under monoculture model was higher than intercrop model at the same soil depth. The average temperature of the stages in apricot germination was monoculture > the distance of 2 m to stem of apricot > the distance of 1 m to stem of apricot > air temperature. Conclusion: In the stages in germination of early spring, apricot orchard inter-crop wheat have definite effect to reduce soil temperature. The time change and the soil temperature were gradually ascended. In the period of apricot bloom, the horizontal distance at different levels did not have obvious effect on soil temperature.
