A new late ripening nectarine cultivar‘Fuxiu’was used as test material to study the effects of spraying three kinds of foliar fertilizer on chlorophyll content, net photosynthetic rate, chlorophyll fluorescence parameters of leaves and fruit quality. The results showed that spraying three kinds of foliar fertilizers significantly increased chlorophyll content and net photosynthetic rate, which could improve leaf quality and photosynthetic capacity. And it also increased photosynthetic efficiency, maximum photochemical efficiency, photosynthetic capacity of photosystem II. Spraying foliar fertilizers also increased fruit weight, significantly increased soluble solids, sugar acid ratio, and fruit quality. The effects of‘Taibao’humic acid fertilizer and‘Aijifu’seaweed fertilizer were better.
