黑龙江西部干旱区糜子垄作栽培下适宜品种筛选

摘要

[目的]筛选适合黑龙江西部干旱区种植的糜子品种,提升该地区糜子产量水平.[方法]在黑龙江西部干旱地区,通过垄作栽培的方法,采用完全随机试验设计,以近些年培育出的6个优质糜子品种为试验材料,进行品比筛选试验.[结果]不同糜子品种的农艺性状和产量不同,株高较高、穗粒数较多的品种为赤黍8号;千粒重较重、籽粒饱满的品种为榆糜2号;产量较高的粳糜子品种为固糜21号,较榆糜2号、陇糜12号分别高9.26%、24.21%;产量较高的糯糜子品种为冀黍2号,较晋黍9号、赤黍8号分别高17.12%、47.73%.[结论]为了获得较高的糜子产量,建议在黑龙江西部干旱区扩大固糜21号和冀黍2号的种植面积.%[Objective] To screen suitable proso millet variety under the raised-bed planting in the arid region of western Heilongjiang Province, and enhance the production level of proso millet in this region.[ Method] As materials of 6 high quality proso millet varieties,the screening varie-ties experiment was carried in arid area of western Heilongjiang Province under the raised-bed cultivation,using complete randomized experimen-tal design.[ Result] Different agronomic characters and production of proso millet varieties were different.There were higher plant height and higher spike grain number in Chishu 8,heavier 1000-grain weight in Yumi 2.The yield of Gumi 21 was more than Yumi 2,Longmi 12 respectively 9.26% and 24.21% in non-waxy proso millet,and the yield of Jishu 2 was more than Jinshu 9, Chishu 8 respectively 17.12%,and 47.73%,in waxy proso millet.[ Conclusion] It is recommended to expand Gumi 21 and Jishu 2′s planting area in arid area of western Heilongjiang Province to obtain higher proso millet production.
