Effect of Amount of Nitrogen Fertilizer Applied on Yield of Green Asparagus
摘要
Abstract
[Objective]Effect of amount of nitrogen fertilizer applied on green asparagus was analyzed .[Method]Using three-year Asparagus officinalis UC308 as experimental material,the effect of different amount of nitrogen fertilizer on yield of green asparagus was studied in the production base.[Result]Compared with the control,green asparagus' yield of applying nitrogen fertilizer increased greatly.The application amount of pure N 475.0 kg/hm2 had the best effect on green asparagus , which increased yield by 38.2％ compared with the control plot of conventional application (pure N 127.5 kg/hm2).The yield of application amount of pure N 301.5 kg/hm2 came second, which increased by 20.7％ compared with the control plot.And the yield of application amount of pure N 648.8 kg/hm2 increased by 12.8％.Compared with the control,average yield of applying nitrogen fertilizer increased by 17.0％.[Conclusion]Under this experimental condition, the optimum recommend local fertilization amount of pure N was 407.3 kg/hm2 .关键词
