摘　　要：为了解在油茶幼林地间种大豆对林地土壤的影响情况,从而为油茶林地间种提供科学依据,对间种大豆的油茶幼林地的土壤养分含量进行了测定与分析。结果表明:间种大豆能改善油茶林地土壤的理化性质,促进油茶幼林生长;可改善土壤pH值,并有效提高土壤有机质和氮、磷、钾的含量。在油茶幼林地间种大豆可以有效利用土地,提高油茶林地的经济效益,是一种较好的林地经营模式。In order to learn the effects ofintercropping soybean on soil at Camellia oleifera young forest, and to provide a scientific basis for intercropping at C. oleifera forest, nutrient contents in soil were determined and analyzed at C. oleifera young forest intercropping soybean. The results show that intercropping soybean can improve soil physicochemical properties and pH value, promote growth of C. oleifera young forest, and increase contents of organic matter, N, P and K. Intercropping soybean at C. oleifera young forest is a suitable forest management model which can effectively utilize soil and increase economic benefits.
