Abstract: ObjectiveIn this paper,the effects of spraying different foliar fertilizers on yield and quality of banana were investigated so as to provide reference for selecting quality and high-yield planting of banana.MethodAmino acids, alginic acid and microelement foliar fertilizers were sprayed during banana backcomb period,the indexes including peel color difference,fruit characteristics,nutrient content and yield were dynamically traced.ResultBanana peel brightness enhanced significantly(P<0.05,the same below)after spraying amino acid and alginic acid foliar fertilizers,and their fruit finger lengths were 22.03 and 21.01 cm respectively,which were significantly higher(13.50% and 8.24% respectively) than that of control(spraying clear water,CK).After spraying amino acid foliar fertilizers,nitrogen accumulation(4.04 g/plant)and potassium accumulation(2.87 g/plant)were significantly higher than those of CK,and its yield was 19.39 kg/plant,which was also significantly higher than that of CK.After spraying microelement foliar fertilizers,nitrogen accu-mulation(4.51 g/plant)and potassium accumulation(2.78 g/plant)were significantly higher than those of CK,and its yield was 21.74 kg/plant,which was also significantly higher than that of CK.ConclusionSpraying amino acid and al-ginic acid foliar fertilizers on fruit fingers can significantly improve banana peel brightness during banana backcomb period. And spraying amino acid and microelement foliar fertilizers can significantly improve banana yield and nitrogen and potas-siun accumulation.Therefore,various foliar fertilizers shoule be selected according to the specific goals.
