摘要
引进青贮玉米品种豫青贮23,以荆门市当地主导玉米品种郑单958为对照,研究了不同栽培密度和宽窄行距对单位面积产量及农艺性状的影响。结果表明,豫青贮23青饲料产量显著高于对照品种,且可以作为子粒玉米收获;经统计分析,种植密度、宽窄行方式单因素和交互作用对青贮玉米豫青贮23的产量影响不显著,抽雄后30 d即可收获。
Yuqingzhu 23 was introduced and compared with Zhengdan 958,the dominant maize variety in Jingmen city,the effects of different planting densities and wide and narrow row spacing on yield per unit area and agronomic traits were studied. The results showed that the yield of Yuqingzhu 23 was significantly higher than that of the control varieties,and it could be harvested as seed corn.According to statistical analysis,the single factor of planting density,wide and narrow path and interaction had no significant effect on the yield of silage maize,which was harvested 30 days after sprouting.
