摘要
为研究化肥减施对嫁接西瓜长势、产量和品质的影响,以西瓜常用施肥量为对照,通过20%~80%的氮肥和磷肥的减施,对‘甬砧3号’嫁接的‘甬蜜2号’进行处理,分析肥料减施对西瓜长势、产量和品质的影响。结果表明,处理间的西瓜单果质量(4.98~6.11 kg)和果形指数(1.02~1.05)差异不显著,长势(主蔓长2.39~2.56 m)和糖度(9.79%~11.21%)差异显著。除边缘糖度外,其余性状均表现为随化肥施用量的增加而增加的趋势,其中减施40%(尿素和过磷酸钙667 m^2施用10.8 kg)和20%(尿素和过磷酸钙667 m^2施用14.4 kg)氮肥和磷肥的综合效果较佳。
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 (4.98-6.11 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 m^2, separately) and 20% (N and P fertilizes 14.4 kg per 667 m^2 , separately) reduction of N and P fertilizers. The results indicated that the efficiency could be increased through the reduction of N and P fertilizers.
