摘　　要：铁肥树干强力高压注射以二价铁主要沿中央木质部的导管运输 ,大部分向下运往根系 ,致使根中贮存大量的铁 ,向上运稍难 ,运输速度每小时达数百厘米 ,矫正缺铁失绿症的速度比根系输液慢 ,但由于根中贮存大量的铁 。The iron fertilizer by high-pressure trunk-injection indicates:Fe2+ was transported along the central xylem ,most of Fe2+ was transported and stored in roots.It was a little difficult for Fe2+ to be transported upto leaves.The speed of transportation reached several hundred centimetres per hour when trunks were injected with iron fertilizer with high-pressure.Regreening of iron deficiency chlorosis trees was slower but the effect of correcting iron deficiency chlorosis lasted longer when trunks were injected with iron fertilizer than iron fertilizer was root-injected.
