| 摘 要： | 对桂中、桂北油茶主要产区10个油茶成林林地土壤和叶片养分含量进行分析，结果表明：10个取样点的土壤属于强酸或极酸性土壤，8个取样点土壤的有机质含量及4个取样点土壤的碱解氮含量处于缺乏状态，全部取样点土壤的速效磷含量以及6个取样点土壤速效钾含量处于极缺乏水平；叶片全氮和全钾含量与土壤中pH值、有机质和碱解氮和速效钾的相关性不明显，但叶片中全磷含量与土壤中速效磷含量极显著相关，叶片全磷含量能较好的反映土壤中速效磷含量。

| Abstract: | The concentrations of nutrient elements in Camellia oleifera leaf and soils from ten major Camellia oleifera producing areas in Guangxi were measured in this paper. The results showed that all areas were strong acid soil, eight areas were lack of organic matter and six areas were lack of available nitrogen in soil, all areas were very lack of available phosphorus and six areas were very lack of available potassium in soil. The correlation between the total nitrogen content, total potassium content in leaf and pH value, available nitrogen content, available potassium content in soil were not significant, but there was significant correlation between total phosphorus content in leaf and available phosphorus content in soil. So the total phosphorus content in leaf can reflect the available phosphorus content in soil. |
