摘要： 生物统计表明:采样地点及年份间的差异对巴林脐橙叶片元素含量有明显的影响;叶片微量元素含量的变异系数均显著高于大量元素。初步提出丰产巴林脐橙叶片元素含量的适宜指标:N 2.8~3.3,P 0.14~0.18,K 1.4~2.1,Ca 2.0~4.0,Mg 0.25~0.45(以上单位×10-2),Cu 5~18,Zn 20~50,Mn 20~100,Fe 50~160,B 25~100(以上单位×10-6)上列指标可供营养诊断之参考。

Abstract: The optimum range of macro-and micro-element contents in the leaves of Parent Navel Orange in south Fujian were studied in 1994~1995. The amount of elements in the leaves within the same cultivar was definitely affected by different localities and years for sampling. The variation coefficients of micro-element contents in the leaves were higher than those of macro-element contents. The present study recommends that the values of the optimum ranges of the mineral elements in the leaves of spring shoots of Parent Navel Orange are:N 2.8×10-2~3.3×10-2, P 0.14×10-2~0.18×10-2, K 1.4×10-2~2.1×10-2, Ca 2.0×10-2~4.0×10-2, Mg 0.25×10-2~0.45×10-2, Cu 5×10-6~18×10-6, Zn 20×10-6~50×10-6, Mn 20×10-6~100×10-6, Fe 50×10-6~160×10-6, B 25×10-6~100×10-6. These diagnostic criteria may provide the parameters of fertilizer guide.
