摘要
对贵州南部 8个县 4 4个甜橙园区甜橙叶片矿质元素含量及适宜范围分析表明 ,贵州南部甜橙叶片中的氮、磷两个常量元素及钙、镁、铁、锌的变化幅度较小 ;而钾、锰及硼的变化幅度较大。初步认为贵州南部甜橙叶片矿质元素含量的适宜范围 :氮 2 .5 %~ 3.1% ,磷 0 .14 %~ 0 .2 0 % ,钾 0 .70 %~ 1.80 % ,钙2 .0 0 %~ 5 .0 0 % ,镁 0 .2 5 %~ 0 .5 5 % ,锰 2 0~ 5 0 (mg/kg) ,铁 10 0~ 180 (mg/kg) ,铜 4~ 10 (mg/kg) ,锌 15~30 (mg/kg) ,硼 30~ 10 0 (mg/kg)。
The mineral nutrition status of orange in south area of Guizhou was studied by leaf analysis. The result indicated that content range of N, P, Ca, Mg, Fe and Zn in the leaves of orange was narrow, and K,Mn, B was more wide. Values of optimum range of the mineral elements in the leaves of orange are: N 2.5%~ 3.1% , P 0.14%~ 0.20% , K 0.70%~1.80%, Ca 2.00%~5.00%, Mg 0.25%~0.55%, Mn 20~50(mg/kg), Fe 100~180(mg/kg), Cu 4~10(mg/kg), Zn 15~30(mg/kg), B 30~100(mg/kg)?
