Abstract:
Taking 9-year-old Fuji apple trees M26 as material,the effect of formula fertilizer and controlled release fertilizer on leaf size,photosynthetic rate,fruit yield and quality were studied.The results showed that leaf size increased significantly using formula fertilizer,and the color of leaf was dark green.Compared with control treatment,the leaf area,leaf fresh weight,dry weight increased 3.5%,5.2%,3.0%,respectively,yield increased 10.9%.Fruit firmness,soluble solids content increased and total acid content decreased.The application of controlled release fertilizer increased the yield by 5.5%；fruit hardness,soluble solids content and total acid content increased.
