Abstract: The effects of row spacing and seeding rate on seed yield and yield components of Bromus inermis Leyss.were studied in Jiuquan、Tongliao and Suihua.Results show that row spacing is the primary factor affecting seed yield.The seed yield of 30 cm row spacing is significantly higher than that of 50,70,and 90 cm row spacing.Seeding rates have no significantly different affects on seed yield.Different planting sites have significant difference on seed yield and yield components (P<0.05).The highest seed yield (1 368.43 kg·hm-2) is obtained in Tongliao.The seed yield in Jiuquan is 1 005.19 kg·hm-2 and the lowest yield is in Suihua (284.78 kg·hm-2).Row spacing has significant affect on shoot numbers per square meter and per thousand-seed weight (P<0.05).Seeding rates do not have significant effect on yield components.

Key words: Bromus inermis Leyss., Row spacing, Seeding rate, Seed yield, Yield components

摘要: 在酒泉、通辽、绥化3地同时进行了行距与播种量对无芒雀麦种子产量及产量组分影响的试验研究,结果表明:同一地区行距是影响无芒雀麦种子产量的主要因素,播种第2年30 cm行距的种子产量显著高于50 cm,70 cm和90 cm行距处理;播种量对种子产量没有显著影响;3地间种子产量具有显著差异(P<0.05),通辽地区产量最高为1368.4 kg.hm-2,酒泉次之是1005.2 kg·hm-2,绥化最低为284.8 kg·hm-2。行距对无芒雀麦生殖枝数/m2和千粒重影响显著(P<0.05),播种量对无芒雀麦产量组分影响不显著。
