Variation Characteristics of Soil Temperature and Moisture under Different Agro-forestry Models in Langzhong

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:1.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 significant,while the effects of time and interaction between time and agro-forestry models were extremely significant.
