The effects of iron fertilizer on iron contents and quality of strawberry（Sweet Charlie）were studied by spraying three different forms of iron fertilizer on leaves.The results showed that spraying foliar fertilizer was an effective way to increase the active iron contents,SPAD values,peroxidase(POD)and catalase(CAT)activities of strawberry leaves,especially in case of small molecular orgnanics chelated iron fertilizer,comparing with the control(spraying water),which were respectively significantly increased by 76.44%,6.25%,180.00% and 61.72% respectively;Comparing with the control,the iron contents of fruit were increased remarkably by 35.46% and 27.79% by spraying small molecular orgnanics chelated iron fertilizer and EDTAFe,respectively,but it showed no difference with the control when spraying FeSO4.Moreover,ratio of sugaracid and soluble solid substance contents were respectively improved by 18.70% and 30.89% by spraying small molecular orgnanics chelated iron fertilizer which had significant differentiation with the control.The corelation analysis showed that there was a positive significant linear correlation between active iron content and SPAD values,POD and CAT activities of strawberry leaves,total iron content were in positive linear corelation with ratio of sugaracid of strawberry.According to the current study,iron foliar application enhanced physiological metabolism and iron content of leaves and improved the iron accumulation to some extent and quality of strawberry,small molecular orgnanics chelated iron fertilizer was recommended as an optimal foliar iron fertilizer.
