| 摘 要： | 目的]研究施氮量对绿芦笋产量的影响。方法]在芦笋生产基地,以3年生芦笋UC308为试材,研究不同氮肥施用量对芦笋产量的影响。结果]增施氮肥处理比常规施肥处理增产明显,处理N3(纯氮475.0 kg/hm~2)产量最高,较常规施肥对照处理N1(纯氮127.5 kg/hm~2)增产38.2%,其次为处理N2(纯氮301.5 kg/hm~2),增产20.7%,高肥处理N4(纯氮648.8 kg/hm~2)增产较少,为12.8%。增施氮肥处理N2、N3、N4平均产量较常规施肥处理N1增加17.0%。结论]该试验条件下,推荐最佳氮肥用量为纯N 407.3 kg/hm~2。

| 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 . |
