| 摘 要： | 采用裂区设计,研究了不同施氮水平和追氮时间对玉米高水肥品种东单60子粒产量构成因素及子粒产量的影响。结果表明,施氮肥能增加玉米的穗数、穗粒数、千粒重;不同施氮水平对玉米子粒产量影响较大,施氮可增产3.5%～34.2%,在本试验条件下,施氮量为422kg·hm-2的处理,产量达最高;不同追氮时间对玉米千粒重的影响差异显著。

| Abstract: | The experiment was designed in a split plot,which studied the effect of applying different levels of nitrogen and top application time on grain yield and its components of Dongdan 60.The results indicated that nitrogenous fertilizer can increase ears per ha.,grains per ear and 1000-grain weight.There were larger effects of nitrogenous fertilizer on grain yield of maize,which increased by 3.5%-34.2%.The quantity of nitrogenous fertilizer with the highest yield was 422 kg·hm-2 in this experiment.The 1000-grain weight of maize among different topdressing time showed significant differences. |
