摘　　要：通过探讨‘晋大麦（啤）2号’在当地生态环境下的最佳综合配套高产栽培技术,为推广种植本品种获得高产高效提供科学的理论依据。对该品种进行了不同播期、密度与产量关系的研究,以明确产量与播期、播量的关系。结果表明：播量从60.00-120.00 kg/hm2范围内,随播量增加产量随之提高,变幅在6186.98-6573.66 kg/hm2,反之,播量再高时,产量降低。播期以9月30日至10月5日产量较高,变幅为6600.33-6693.67 kg/hm2,随之播期推迟产量变低。选择适宜的播期和播量,对‘晋大麦（啤）2号’品种获得高产至关重要。In order to explore the best comprehensive high yield cultivation techniques of ＇Jindamai2＇ in the local ecological environment,and provide scientific theory basis for planting this variety with high yield and high efficiency,the study on the relationship between yield and different seeding times and seeding densities of this variety was conducted.The results showed that in the sowing amount range of 60.0 kg/hm2 to 120.0 kg/hm2,the yield increased along with the sowing quantity increase,the amplitude ranged from 6186.98 to 6573.66 kg/hm2;on the contrary,when the sowing quantity was further increased,the yield reduced.Sowing date from September 30 th to October 5th could result in higher yield,the amplitude ranged from 6600.33 to 6693.67 kg/hm2,and when sowing date was further delayed,the yield reduced.Suitable sowing date and sowing quantity were crucial to gain high yield of the barley variety ＇ Jindamai2＇.
