摘　　要：对3年生油茶幼林进行了6种不同模式间种试验,分析了不同模式对油茶幼林树体生长的影响,并对间种的经济效益进行了分析。结果表明:间种的油茶幼林树体的地径、树高及冠幅生长量均高于对照,说明间种对油茶幼林生长有一定的正面影响。不同间种模式的经济效益存在明显差异,最高的为玉竹间种模式,而大豆间种模式最低。对各生长指标及经济效益进行综合分析,筛选出最佳间种模式为玉竹间种模式。The intercropping experiments of three-year-old young Camellia oleifera forest were carried out under six different modes,in order to analyze the effects of mode on the growth of young Camellia oleifera forest,and the economic benefits of intercropping were further analyzed.The results showed that the growth of ground diameter,plant height and crown width of young Camellia oleifera forest under intercropping patterns were all higher than those of CK,indicating that intercropping have some positive effects on the growth of young Camellia oleifera forest.The economic benefits of different intercropping patterns were significantly different,while the highest economic benefit was under Polygonatum odoratum pattern,and the lowest benefit was under soybean pattern.Comprehensive analyses of growth indicator and economic benefit were carried out,and the Polygonatum odoratum pattern was selected as the best pattern.
