基　　金：东北南部春玉米密植高产宜机收品种筛选及配套技术(2016YFD0300304-05);国家玉米产业技术体系铁岭综合试验站(CARS-02-45);辽宁北部区适宜全程机械化作业玉米新品种培育(2019JH1/10200001-11)。

摘　　要：在辽北地区大田条件下,以迪卡159、泽玉9811、宏硕899、铁研58、丹玉311、粒收1号6个玉米品种为试验对象,在供试品种达到生理成熟4周后使用凯斯AF4088玉米收获机进行籽粒直收,并进行相关调查研究。结果表明:采用籽粒机械化直收技术,各品种玉米平均产量为768.2 kg/667 m^2,倒伏倒折率小于2%,籽粒破碎率和机收损失率均符合国家标准(小于5%),收获时籽粒含水量小于国家玉米机收品种审定标准(25%)。研究结果可为玉米籽粒机械化直收技术在辽北地区的推广应用提供理论与技术支撑。Under the conditions of Dita in the northern region of Liaoning,6 maize varieties including Dika 159,Zeyu 9811,Hongshuo 899,Tianyan 58,Danyu 311 and Lishou No.1 were selected as experimental objects,and the Case AF4088 corn harvester for direct grain harvest after 4 weeks of physiological maturity of the test varieties were used,and related investigation and research were carried out.The results showed that:The average yield of each variety of corn was 768.2 kg/667 m^2,the reverse fold rate was less than 2%,the grain crushing rate and the machine yield loss rate were in line with the national standard(less than 5%),and the water content of the grain at harvest was less than the national corn machine yield(25%).The results can provide theoretical and technical support for the popularization and application of the mechanized direct harvest technology of maize seed grain in northern of Liaoning province.
