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
