【摘要】Taking a walnut (Juglans regia)-wheat (Triticum aestivum) intercropping system as the research object,monoculture systems of two species as the controls,this paper discussed the influence of agroforestry system on the temperature of shallow soil layers (5,10,and 25 cm) to provide theoretical basis for agroforestry structure optimization

and

water

regulation.In

summer,the

maximum

temperatures in a day and average temperatues during high temperature period in three soil layers were in the order of wheat monoculture＞walnut monoculture＞walnut-wheat intercropping,and there were significant differences among the three.In 5 cm soil layer,the temperature diurnal range of the three land use patterns also characterized as wheat monoculture＞walnut monoculture＞walnut-wheat intercropping.Monthly average temperature of the three soil layers of walnut-wheat intercropping was less than the two monoculture systems during March to October,instead,walnut-wheat intercropping system was higher than the two monoculture systems in November,and there were significant differences among the three land use patterns.Above all,the results showed the walnut-wheat intercropping
