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 analysis of the mineral elements content and the suitable range of the sweet orange leaves in 44 sweet orange garden plots in 8 counties in southern Guizhou province showed that the two nitrogen and phosphorus elements and the changes of calcium, magnesium, iron and zinc in southern sweet orange leaves Small; and potassium, manganese and boron greater changes. The suitable range of the mineral elements content of sweet orange leaves in the south of Guizhou is preliminarily thought as: nitrogen 2.5% ~ 3.1%, phosphorus 0.14% ~ 0.2%, potassium 0.70% -1.80%, calcium 2.0% 0.5 to 5 0% of magnesium, 2.5 to 0.55% of magnesium, 20 to 50 mg / kg of iron, 10 to 180 mg / kg of iron, 4 to 10 mg / kg), zinc 15-30 (mg / kg) and boron 30-10 0 (mg / kg).
