| 摘 要： | 本试验采用播种方式、品种、追肥量三因素裂区设计 ,研究了不同处理对特早熟夏玉米的产量及产量构成要素的影响。结果表明 :⑴硬茬直播方式产量略高于旋耕露地及旋耕覆膜方式 ,三者差异未达显著水平。三种播种方式各有其特点 ,在特早熟夏玉米区可选择使用。⑵冀承单 3号产量显著高于屯早 1号。⑶不同追肥量对特早熟夏玉米产量影响不明显 ,播种方式与追肥量互作效应显著

| Abstract: | The experimental design was a three factors split-split-plot. The three factors were seeding method, variety and top dressing rate. The experiment studied different treatment combinations effect yield and its components on especial-early summer corn. The result showed that: (1) The no-till seeding method yield was higher than other methods,but three methods' variance is insignificant. The three methods have own merits and can be selectively adapted in especial-early summer corn zone.(2) Cultivar Jichengdan 3 grain yield was markedly higher than cultivar Tunzhao 1's.(3) Different top dressing rate effects yield is insignificant . Seeding method × top dressing rate interaction effect is significant. |
