武鸣县一菠萝园菠萝植株全部失绿黄化,经诊断为锰过量导致生理性缺铁。经施铁肥后,取得显著治疗效果。叶片分析和土壤分析进一步证明,过量锰导致菠萝植株体内Mn/Fe比高达7.8,为正常植株的3倍以上。锰的绝对含量为正常植株的4倍以上。锰铁平衡的严重失调,引起生理性缺铁,因而出现失绿黄化症。对于菠萝来说,当Mn/Fe比在5以上,便可能诱发缺铁失绿。
Abstract：Pineapple Chlorosis was occurred in an orchard in wuming county and was diagnosed as a physiological iron-deficiency caused by excessive manganese. After spraying with iron fertilizer, a curative effect was obtained. By the leaves and soil analysis were further demonstrated that excessive manganese led to the Mn/Fe ratio in pineapple plant was high as 7.8, this figure is 3 times higher than that of normal plant, and the absolute contents of manganese was 4times of that in normal plant. Critical disorder in iron-manganese balance results in physiological iron deficiency. Thus, chlorosis.appeared. As for pineapple., when the Mn/Fe ratio up to 5, the iron-deficiency and chlorosis may induced.
