The effects of adding micronutrient fertilizers on the occurrence ofyellowing disease，yield and quality of fruit trees were compared and analyzed.The results showed that the application of added micronutrient fertilizers could reduce the occurrence of yellowing disease，promote the sprouting of new shoots，improve the growth condition offruit trees，increase the yield and fruit quality，and be more conducive to the healthy growth of appleand hazelnut trees compared with the application of conventional fertilizer treatments.
