摘　　要：针对浙南山区果园水土流失问题以及目前园林市场的需求，在山地果园中进行了伞房决明和槐叶决明的套种试验。结果表明：果园套种伞房决明和槐叶决明的地块与清耕果园相比，在高温季节不同土层可降低土壤温度1．3～3．6℃，土壤含水量分别提高了11．8％和12．2％，速效N分别提高了95．2％和109．5％，速效P分别提高了12．5％和15．6％，速效K分别提高了8．8％和11．8％，有机质分别提高了64．2％和67．9％，套种伞房决明和槐叶决明使土壤孔隙度分别提高了49．0%和37．9％，有效地提高了土壤的理化性质。For the loss of water and soil was serious in Zhejiang southern mountain orchard and the current need of land- scape, tests of inter-planting Cassia corymbosa and Cassia sophora with orchard were made. The results showed that there was a decrease of 1. 3 ~ 1.6℃ in the ground temperature during the high temperature season, an increase of 11.8% and 12.2% apart in soil moisture and the increases of 95. 2% and 109. 5%, 12. 5% and 15. 6%, 8. 8% and 11.8%, 64. 2% and 67. 9% apart for available nitrogen, phosphorus, potassium, organic, an increase of 49. 0% and 37. 9% apart in soil porosity between the inter-planting and clean culture. So inter-planting Cassia corymbosa and Cassia sophora with orchard could improve soil physical-chemistry property effectively.
