[Methods] We selected two types of tea-oil camellia orchards in Yichun, Jiangxi provinceone type having good nesting soils (NS) for digger bees and another without good nesting soils (NNS). We also selected two types of orchards in the Karst region of Wenshan, Yunnan, one type called peak cluster (PC) and another called depression area (DA). Soil penetration resistance, bulk density, water content, temperature, soil particle size, nest density, and visitor abundance, were measured in the four types of orchards. [Results] PC, DA and NNS had significantly higher soil penetration resistance, bulk density and temperature, but significantly lower water content, than NS. No significant differ
