摘要:
 以核桃（Juglans regia）-小麦（Triticum aestivum）间作复合系统为研究对象，以两者各自的单作系统为对照，讨论农林复合系统对生长季5、10 cm和25 cm地温的影响，为优化农林复合结构和水分调控提供理论依据。结果表明，夏季日内5、10 cm和25 cm地温的峰值及高温时段的地温均表现为小麦单作>核桃单作>核桃-小麦间作，且三者间存在显著差异；三者5 cm地温日内波动幅度也表现为小麦单作>核桃单作>核桃-小麦间作。核桃-小麦间作生长季节5、10 cm和25 cm月平均地温，在3-10月份均低于两单作系统且存在显著差异，在11月份则均高于两单作系统且三者间差异显著。总之，核桃-小麦间作可以有效降低生长季高温时段的浅层土壤温度，这有利于减少系统内土壤水分的无效蒸发和提高水分利用效率；11月份核桃-小麦间作对地温的提高作用有利于间作小麦根系的冬前生长。
Abstract:
 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 system could reduce the shallow soil temperature effectively during high soil temperature period,which had great significance for reducing ineffective evaporation and improving water use efficiency.
