Abstract：For the study of the influence of fertilizers reduction on growth,yield and quality of grafted watermelon,the influence of fertilizers reduction on the growth,yield and quality were studied on ‘Yongmi No.2’ grafted on Yongzhen No.3,20％ to 80％ of the N and P fertilizers reduction were used,while conventional fertilizers application was set as control.The results showed that no significant difference could be detected in fruit weight (4.98-6.l 1 kg) and fruit shape index (1.02-1.05) of watermelon among the treatments.However,there were significant differences in growth and sugar content among the treatments.The phenotypes increased with the increasing application of the fertilizers,except the edge sugar content.Among the treatment,the comprehensive effect showed better on the 40％ (N and P fertilizes 10.8 kg per 667 m2,separately) and 20％ (N and P fertilizes 14.4 kg per 667 m2,separately) reduction of N and P fertilizers.The results indicated that the efficiency could be increased through the reduction of N and P fertilizers.
