Abstract: Taking sweet cherry varieties ‘Sammit’ and ‘Fuchen’ as experimental materials, liquid silicon fertilizer was applied in five different ways, root irrigation, leaf surface spraying, trunk lifting, trunk lifting+root irrigation and trunk lifting+root irrigation+leaf surface spraying.The fruit mass, leaf area, fruit shape index, soluble solid matter, soluble sugar, titratable acid, and chlorophyll content of leaves were measured after fruit ripening to investigate the effects of various application methods of silicon fertilizer on the growth and fruit quality of sweet cherry, in order to provide reference for the rational application of silicon fertilizer on cherries.The results showed that the root irrigation application method of silicon fertilizer yielded better outcomes.It was anticipated that the application of silicon fertilizer could effectively enhance the fruit weight,leaf area,fruit shape index,soluble solids,soluble sugar,titratable acid,leaf chlorophyll content,and other indicators of sweet cherries.
