测定、分析广东省肇庆地区五和镇新建贡柑果园土壤养分、树体矿质元素含量及分布特征和相关性。结果表明：供试果园土壤pH值偏低，有机质含量中等偏低，土壤缺乏交换性钙、交换性镁和有效硼等元素。叶片中矿质元素含量与土壤养分之间有一定的相关性，春梢和秋梢叶片中不同矿质元素含量分布规律不同，并受土壤相关元素丰缺度、矿质元素在树体内的分配与再分配特性等因素的影响。

Soil and leaves nutrient status and distribution in six new typical Citrus nobilis Lour. gonggan orchards in zhaoqing city were tested. The results showed that:the soil pH of the orchards were low with the average of 4.37;half orchards were at the middle level of the soil organic matter;exchangeable Ca and exchangeable Mg and effective B content were scarce in all orchards. The correlation between mineral elements in leaves and nutrient in soil was remarkable. The distribution of the mineral element content in spring shoot was different with that in autumn shoot. And it was affected by shortage and extensive degree of relative soil elements content and distribution and redistribution of mineral element content in the whole tree.
