摘　　要：于2015-2016年10月底至11月初,采集6个浙江省油茶Camellia oleifera主产区20个县(市、区)150个土壤样品,检测其全效、速效养分及中、微量元素等13个肥力指标,对全量数据集做主成分分析,选取高因子载荷指标,确定浙江省油茶土壤肥力评价最小数据集。结果表明,浙江省油茶主产区土壤肥力最小数据集为全N、有效P、交换性Ca、交换性Mg、有效Cu、有效Fe这六6个指标。利用抛物线形隶属度函数对肥力指标进行标准化,结合权重系数得出各样区最小数据集肥力指数。最小数据集肥力指数与单位面积茶油年均产量间的相关性分析结果表明,最小数据集肥力指数与单位面积茶油年产量间呈显著正相关,与全量数据集内梅罗综合指数间呈极显著正相关。From the end of October to the beginning of November in 2015 and 2016,150 soil samples were collected from Camellia oleifera stands in twenty counties of 6 main producing regions of Zhejiang province.Determinations were made on 13 indicators of fertility,such as total nutrients,available nutrients and microelements,etc.Principal component analysis on total data set demonstrated that the minimum data set included the following six indexes,total nitrogen,phosphorus,exchangeable calcium,exchangeable magnesium,available copper,and available iron.The fertility index was standardized by parabolic shape function,and the minimum data set fertility index was calculated according to weight coefficient.The correlation analysis showed that the fertility index of minimum data set had significant positive correlation with annual tea oil yield,and extremely significant positive correlation with nemero comprehensive index.
