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,持效期较长。

关键词: 铁肥, 树干强力高压注射, 苹果, 缺铁失绿症

Abstract: 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.

Key words: Iron fertilizer, High-pressure trunk-injection, Apple trees, Iron deficiency chlorosis
