In order to explore the effect of iron and zinc fertilizer on the antioxidant activity of‘pearjujube'in hilly loess hilly region,8-year-old mountain dwarfing ‘pear-jujube'with uniform and well growth were used as test objects,the effects of different concentrations of iron and zinc fertilizer on vitamin C,total flavonoid content and enzyme content were studied.The results showed that different treatments affected the content of vitamin C in‘pear-jujube'and significantly increased the contents of vitamin C and total flavonoids.The content of 0.6% FeSO4+0.3% ZnSO4 was 2.86 mg·g~(-1) and3.02 mg·g~(-1),which was 21.8% and 105.4% higher than CK respectively(P0.05).The different fertilization treatments effectively reduced the activity of ascorbic acid oxidase and polyphenol oxidase in‘pear-jujube'.Treatment of 0.6% FeSO4+0.6% ZnSO4 showed the highest activity of ascorbic acid oxidase,which was 0.069 mg·g~(-1)· min~(-1) FW,which was 75.1% lower than that of CK.Theactivity of polyphenol oxidase was the lowest in 0.146 mg·g~(-1)·min~(-1) FW,which was 42.0%lower than CK.The polyphenols treated with different treatments could effectively remove hydroxyl radicals,DPPH· and hydrogen peroxide,among which the effect of treatment with 0.6% FeSO_4+0.3% ZnSO4 was the most significant.Comprehensive analysis of the antioxidant effect of the treatment with 0.6% FeSO_4+0.3% ZnSO_4 was optimal.
