- 摘要:
- 为了提高夏播青贮玉米产量,获得优质青贮饲料,通过将夏播青贮玉米品种京科青贮301和富友9号按一定比例(2∶1、1∶1和1∶2)进行同行或间行混播混收,研究不同混播方式和比例对夏播青贮玉米植株农艺性状和产量的影响。结果表明:混播种植对群体内植株生育时期和主要农艺性状影响不显著;不同混播方式下地上部鲜重产量表现为富友9号>间行混播>京科青贮301>同行混播,干物质产量则表现为间行混播>京科青贮301>富友9号>同行混播,同行和间行混播中不同比例(2∶1、1∶1和1∶2)在生物产量上无显著差异(P>0.05)。综合农艺性状和生物产量可知,京科青贮301与富友9号以1∶1比例进行同行混播混收可在夏播条件下获得较高产量和品质,适宜于推广应用。
- Abstract:
- In order to improve the yield of summer silage maize and obtain quality silage,the effect of different mixed planting styles and proportion of two maize varieties(Jingke 301 and Fuyou 9) on the phenophase,agronomic traits and yield was investigated.The results showed that the mixed planting had no significant effect on phenophase and main agronomic traits;the fresh weight yield of different mixed planting styles were Fuyou 9>intercropping>Jingke 301>mixture planting,the dry weight yield were intercropping> Jingke 301>Fuyou 9>mixture planting;the biological yield was not significant between different mixed proportion in intercropping and mixture planting (P<0.05).The sequence was as follows:the yield and quality of treated plants were relatively high when Jingke 301 was mixed with Fuyou 9 with the ratio of 1∶1.
