通过对影响脐橙品质的稀土进行主成分分析,结果表明,脐橙品质与稀土元素均有密切的关系(主成分分析贡献率达到74.9%),其中与轻稀土元素、Y元素有着更密切的关系.脐橙种植过程中,应全面施用稀土微肥.在所有稀土元素不可缺少的前提下,增加轻稀土元素与Y元素的含量比例,更有利于促进脐橙的生长与品质的提高.
通過對影響臍橙品質的稀土進行主成分分析,結果錶明,臍橙品質與稀土元素均有密切的關繫(主成分分析貢獻率達到74.9%),其中與輕稀土元素、Y元素有著更密切的關繫.臍橙種植過程中,應全麵施用稀土微肥.在所有稀土元素不可缺少的前提下,增加輕稀土元素與Y元素的含量比例,更有利于促進臍橙的生長與品質的提高.

Principal component of more earth element(REE)influencing quality of navel oranges was analyzed by principal component analysis method.The result showed that all the rare earth had close relationship to the quality of navel oranges.The contribution rate of REE reached 74.9%.However,it had more close relationship to light rare earth element (LREE) and Y element.Trace fertilizer with overall REE should be applied in navel oranges.On the premise that all the REE was indispensable,increasing the proportion of LREE and Y element would be more beneficial for the growth and the quality improvement of nave oranges.
