摘　　要：寻求大麦新品种蒙啤麦6号在内蒙古东部区不同播种期、密度与产量的关系,集成在该生态环境下的最佳配套高产栽培措施。试验于2019年和2020年进行。以蒙啤麦6号为试材,采用两因素裂区设计,播种期为主区,密度为副区,共计25个处理组合。结果表明,播种期和密度对蒙啤麦6号产量均有显著影响(P<0.05),播种期以5月20—30日为宜,密度以450~600万株·hm^(-2)基本苗为宜。在此条件下,籽粒产量达到最大,为5039.25~5400.00 kg·hm^(-2)。The relationship between different sowing dates,densities and yields of barley variety Mengpimai 6 in eastern Inner Mongolia was studied to seek the best supporting high yield cultivation measures under this ecological environment.The Experiments were conducted in 2019 and 2020.With Mengpimai 6 as the test material,a two-factor split plot design was adopted,with sowing date as the main area and density as the secondary area and a total of 25 treatment combinations were used.The results showed that sowing date and density had significant effects on the yield of Mengpimai 6(P<0.05).The best sowing date was in May 20 to 30,and the best density was 4.5 to 6 million plants·hm^(-2).Under these conditions,the grain yield of Mengpimai 6 reached the maximum,ranging from 5039.25~5400.00 kg·hm^(-2).
