[Objectives]This study was conducted to explore the treatment methods of amino acid selenium fertilizer suitable for increasing the selenium content of mangoes and improving the quality of mangoes,so as to provide a theoretical basis for the production of selenium-enriched mangoes.[Methods]With Tainong mango as a test material,the amino acid selenium foliar fertilizer was applied by eight treatment methods to investigate the changes of selenium,soluble solid,vitamin C,and titratable acid contents in mango flesh and peel.[Results]Spraying amino acid selenium foliar fertilizer increased the selenium content of mango flesh.The selenium contents of the treatment groups T2,T3,T4 and T5 reached the selenium-enriched standard,and the T2 treatment group had the highest selenium content(0.020 mg/kg).The selenium contents in the peel of all treatment groups were greater than the corresponding selenium content in the flesh.Except for T1,the vitamin C contents of other treatment groups sprayed with amino acid selenium fertilizer increased compared with the control,and that of the T2 treatment group increased significantly(P<0.05).Compared with the control,the soluble solids of the treatment groups sprayed with amino acid selenium fertilizer once also increased.The treatment method of spraying amino acid selenium fertilizer with a dosage of 12000 ml/hm2 once(T2)achieved the best effect of increasing the selenium content and improving the quality of mangoes.[Conclusions]This study provides a scientific basis for increasing the selenium content of mangoes and improving the current situation of insufficient selenium intake. 展开更多
