Abstract:: The effect of controlled released fertilizer of ‘Fuji’ orchard was studied，including soil organic matter，pH value，contents of mineral elements and chlorophyll in leaves，shoot length and fruit quality.The results showed that fertilizing decreased the pH value and mineral elements content of soil.The pH value of applying CRFs was higher than that of applying common compound fertilizer，and the effect of applying different CRFs on soil pH value exhibited some differences.Contents of N，P，K in leaves increased by applying CRFs，and there was obvious differences of applying different CRFs.The contents of Ca，Mg and Fe in leaves with applying CRFs increased higher than that with applying same content common compound fertilizer，conversely，the contents of Cu，Mn and Zn reduced.With CRFs’ application，contents of chlorophyll in leaves and shoot length increased apparently.There was same change in firmness，soluble solid，soluble sugar and content of VC of fruit.But the weight of single fruit and titratable acid of fruit reduced，but there was no significant effect on fruit shape index.
