Objective: The present study was set to discuss ecological effects and physiological characteristics of wheat of apricot and wheat intercropping system. Method: The area from Apricot base point to the middle of two rows of apricot trees are divided into three areas: area under the crown, area near crown, area far away from crown. Study on changes in physiological characteristics of ecological indicators in the apricot and wheat intercropping in wind speed, soil temperature, chlorophyll content. Result: The colser from the distance of the apricot, the lower soil water content in wheat field; The wind speed, plant nutrients in apricot and wheat intercropping field are less than that in wheat monoculture field. Soil temperature under 5 cm for the apricot and wheat intercropping system are less than that in wheat monoculture field before 14:00; soil temperature under 5 cm of wheat monoculture field are higher than that of apricot and wheat intercropping system after 14:00. Wheat booting stage is the obvious contradiction of competition for water between wheat and apricot. Compared with different crown area in intercropping system, the area far away from crown demands for more chlorophyll content of wheat. Compared with wheat monoculture field and intercropping system, there was a fight for nutrient between wheat plants and apricot trees in intercropping field. The efficiency of uptaking nutrient of wheat plants was much lower than that of apricot trees nutrient content of less. Conclusion: Under apricot tree and wheat plant intercropping conditions, the closer from the distance of apricot trees, the less the soil moisture content, the less chlorophyll content of wheat plant. The physiological characteristics of wheat in monoculture field were superior to that in intercropping field.
