摘　　要：采用野外调查与室内分析测定的方法,研究了间种对油茶幼林土壤理化性质及生长量的影响。结果表明:在油茶幼林地间种花生和红薯,一定程度上降低了土壤的水分含量,但间种土壤养分含量均优于对照地土壤养分含量,微生物数量也显著高于对照地微生物数量。同时,间种还提高了油茶的新梢长和树高,增加了林地的经济收益。实施油茶幼林间种对改善土壤的理化性质及提高油茶生长量是有效的。Based on the field investigation and soil analysis,effects of interplantion on soil physical and chemical properties and growth of Camellia oleifera young forest were studied.The main research results are as follows： by interplantation with peanut and sweet potato in C.oleifera young forest,the content of soil water was decreased to some extent,but the content of soil nutrient were all better than that of the control groups,and the mumber of microbe were significantly higher than that of the control groups.At the same time,interplantation has increased the length of fresh treetop,tree height and economic income.So,it is effective to improve soil physical and chemical properties and increase the growth by interplantation in C.oleifera young forest.
