摘要：

对间种的油茶幼林林地土壤及生长量指标进行分析测定，应用主成分分析，将10个指标（土壤含水量、土壤有机质含量、全氮含量、全磷含量、水解氮含量、速效磷含量、速效钾含量、细菌数量、新稍长度和树高净生长量）简化为2个主成分，2个主成分所提供的信息量为全部信息量。结果表明：间种能改善林地土壤理化性质及提高幼林生长量，间种红薯与间种花生相比较，间种红薯为最佳油茶林地间种方式。

Abstract:

Analysis and determination of Camellia oleifera young forest soil nutrient and growth by interplanting has been done. 10 indexes including soil water content, organic matter, total nitrogen and P etc. were sampled into 2 principal components using principal component analysis, all of which provided cumulative variance. The result was as below: interplanting can both improve the soil physical and chemical properties and growth of Camellia oleifera young forest. By comparing interplanting peanut and sweet potato，the latter was the best interplanting methods of Camellia oleifera forest land.
