连续2 a在油茶林地内种植美丽胡枝子（Lespedeza formosa）的试验表明：种植美丽胡枝子后在短期内提高了土壤的有机质和全氮、速氮、全钾、速钾等的养分含量，且第一年的增幅比第二年增幅明显，土壤全磷和速效磷含量在种植美丽胡枝子后反而有所降低；同时提高了土壤的蓄水性能和抗冲刷能力，在强降雨条件下试验区的土壤被侵蚀厚度比对照区分别降低0.27 cm和0.25 cm，第1年和第2年土壤的含水率分别提高16.56%和20.92%。

Experiments were conducted on interplanting Lespedeza formosa in Camellia oleifera stand in the spring of 2012 in Lishui, Zhejiang province. Determinations demonstrated that content of organic matter, total N, available N, total K and available K in tested soil increased, and the first year’s increase was larger than the second year’s one. But content of total P and available P decreased. Interplanting of L. formosa in C. oleifera stand could improve water holding capacity and anti-erosion properties of the tested soil. Soil erosion thickness in interplanting stand and edge decreased 0.27cm and 0.25cm compared to that in the control ( pure C. oleifera stand ). Moisture content in the soil of interplanting stand increased 16.56%and 20.92%in the first and second year than that in the control.
