摘　　要：本文通过在农林复合系统中,4种不同模式(核桃+川明参(C)、核桃+桔梗(J)和核桃+藿香(H),以核桃纯林作为对照),进行了土壤的理化性质、温度与湿度的测定,并对比,得出以下结论:在4种农林药模式下1、土壤上层土壤理化性质与下层土壤理化性质的差异不明显;2、各模式间温度差异不显著,而时间效应以及时间和各处理间的交互效应达极显著水平;3、各模式间相对湿度不存在显著差异,但时间效应以及时间和处理交互效应达极显著水平。Soil physical properties, temperature and moisture were determined under 4 agro-forestry models （ including Juglans regia ＋ Radix Chuanmingshinis Violacei （ C ）, Juglans regia ＋ Platycodon grandiflorus （J） ,Juglans regia ＋ Agastache rugosa （H） ） and Juglans regia control （CK） ）. The results showed that under different agro-forestry models：l. The differences of soil physical properties were not significant between the upper and lower soil . 2. The differences of soil temperature among different agro-forestry models were not significant, while the effects of time and interaction between time and agro-forestry models were extremely significant. 3. The differences of soil moisture among different agro-forestry modes were signifi- cant,while the effects of time and interaction between time and agro-forestry models were extremely significant.
