Abstract: In order to investigate the response mechanism of chlorophyll to controlled-release fertilizer, as well as provide a theoretical basis for the usage of controlled- release fertilizer in fruit tree. Apple special controlled- release fertilizer and general fertilizer were used as test materials in this experiment. Different nutrient content of controlled-release fertilizer were designed to study the effect of controlled-release fertilizer on apple leaf chlorophyll a, chlorophyll b and total chlorophyll content. The results showed that controlledrelease fertilizer increased the content of chlorophyll a, chlorophyll b and total chlorophyll and the content increased significantly was in the CRF3 (19- 7- 19) treatment which increased by 4.8% , 7.3% and 5.6% respectively. Controlled- release fertilizer increased the chlorophyll content, promotes photosynthesis, which improved the yield and the quality of apples effectively.
