Abstract:
Different rates of N fertilizer,such as no fertilizer treatment (the control treatment,CK),100 kg?hm-2 (N1),200 kg?hm-2 (N2),300 kg?hm-2 (N3),and 400 kg?hm-2 (N4) were conducted,to study the response of N fertilizer rates on growth,yield and quality of ‘Shuguang’ nectarine.The results showed that N fertilizer applied could significant improve the growth of nectarine shoot,which gradually increased as N rates increase.Compared to CK treatment,N fertilizer applied could develop the nectarine yield and fruit weight;however when more than 200-300 kg?hm-2,agronomic N use efficiency and partial N factor productivity significantly reduced as yield increasing basically stagnated.Meanwhile,N fertilizer significant influenced the appearance and inner quality of ‘Shuguang’ nectarine.Reasonable N application rate could increase nectarine longitude,lateral and coloring,and improve nectarine soluble solids content,vitamin C,and soluble sugar,while decrease acid content,to improve nectarine quality and flavor.However,luxury N fertilizer applied could reduce nectarine coloring,soluble solids content,vitamin C,soluble sugar.In conclusion,to improve nectarine yield and quality,N rate should be applied scientifically and reasonably.
