| 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 could both improve the soil physical and chemicalp roperties and growth of Camellia oleifera young forest.By comparing interplanting peanut and sweet potato,th... |
