摘要
对枳砧椪柑叶片营养元素含量适宜范围的统计分析表明:采样地点及年份间的差异对叶片元素含量有重要的影响;叶片各元素含量的变异系数差异较大,且微量元素含量的变异系数多显著高于大量元素。初步提出丰产枳砧椪柑叶片元素含量的适宜范围:氮2.90%～3.50%,磷0.12%～0.16%,钾1.00%～1.70%,钙2.50%～3.70%,镁0.25%～0.50%,铜4.0～16.0×10^(-6),锌20.0～50.0×10^(-6),锰20.0～150.0×10^(-6),铁50.0～140.0×10^(-6),硼20.0～60.0×10^(-6).上列标准可作为营养诊断之参考。
This paper reports the results of our study on the optimum range of 10 mineral elementcontents in the leaves of productive‘Ponkan’mandarin on trifoliate orange rootstock in southFujian of China during 1989～1990.The amount of macro—and micro—elements in theleaves within the same stockscion combination(‘Ponkan’/trifoliate orange)was definitelyaffected by different localities and years for sampling.The statistical analysis indicated thatthe variation coefficients were higher for most micro—element contents(especially Mn,Cuand B)in the leaves than that for macro—element contents.The values of optimum range ofthe mineral elements in the leaves of spring flushes of‘Ponkan’/trifoliate orange are:N2.90%～3.50%,P0.12%～0.16%,K1.00%～1.70%%,Ca2.50%～3.70%,Mg0.25%～0.50%,Cu4.0～16.0×10^(-6),Zn20.0～50.0×10^(-6),Mn20.0～150.0×10^(-6),Fe50.0～140.0×10^(-6),B20.0～60.0×10^(-6).These diagnostic criteria are recommended to be reference basisfor the fertilizer guide.
