摘　　要：试验采用4个播期T1(10月31日)、T2(11月5日)、T3(11月10日)、T4(11月15日)和4个播量Q1(187.5 kg/hm^2)、Q2(225.0 kg/hm^2)、Q3(262.5 kg/hm^2)、Q4(300.0 kg/hm^2),研究不同播期播量对苏引麦3号苗用及啤用产量的影响。结果表明,以麦苗利用为目的的大麦生产,在当地生产条件下,播期为11月5日、播量为300.0 kg/hm^2的条件下,苏引麦3号的麦草鲜质量和干质量产量达到较大值,分别为40 720.35、4 840.80 kg/hm^2;以籽粒利用为目的的大麦生产,则在播期为10月31日、播量为262.5kg/hm^2的条件下,苏引麦3号的籽粒产量达到最大,为6 536.46 kg/hm^2。The aim of this study was to investigate the effects of different sowing dates and planting densities on the seedling and grain yields of the barley variety Suyinmai No. 3, whose seedlings and grains are produced for making health food and beers, respectively.The field trial involved four sowing dates(October 31, November 5, November 10, and November 15 in 2018), and four planting densities(187.5, 225.0, 262.5, and 300.0 kg/hm^2);the combination of different sowing dates and planting densities resulted in 16 treatments. The results showed that under the local production conditions, the treatment combining the sowing date of November 5 with the planting density at 300.0 kg/hm^2 attained the highest seedling yield, with fresh and dry weights reaching 40 720.35 kg/hm^2 and4 480.80 kg/hm^2, respectively. On the other hand, for barley production with the purpose of harvesting the grains to make beers, the treatment combining the sowing date of October 31 with the planting density at 262.5 kg/hm^2 showed the maximum grain yield of6 536.46 kg/hm^2.
