优质耐密青贮玉米品种的筛选试验

Selection and Demonstration Test of High Quality and Density Tolerant Silage Corn

2020年在内蒙古通辽市6个高效节水核心示范区开展了无膜浅埋滴灌水肥一体化模式下优质耐密青贮玉米品种鉴选与示范的筛选试验,以文玉3号(CK)为试验对照,参试品种为蒙青贮1812、东单11、北农青贮368、禾玉9566、蒙青贮266共等5个品种,测定各青贮玉米品种的产量,为引导农牧民科学选择和种植优质、高产,多抗、粮饲通用的青贮玉米新品种提供依据。结果表明,综合品种的产量、病虫害抗性、倒伏情况及2019年品种筛选试验结果,蒙青贮1812、北农青贮368、蒙青贮266等品种表现高产、稳定,建议生产上推广应用,其他品种则有待进一步试验验证。

In 2020, six high-efficiency water-saving core demonstration areas in Tongliao City, Inner Mongolia will carry out the selection and demonstration test of high-quality dense-tolerant silage corn varieties under the integrated mode of water and fertilizer integration of non-film shallow drip irrigation. Wenyu No. 3(CK)was used as the experimental control. Set up six treatments of Mongolian silage 1812, Dongdan 11, Beinong silage 368, Heyu 9566, and Mongolian silage 266, the yields of silage corn of different treatments were measured, and high-quality and densitytolerant corn were identified Silage corn varieties provide a reference basis for guiding farmers and herdsmen to scientifically select and plant high-quality, high-yield, multi-resistant grain and new varieties of silage corn.Comprehensive yield, pests and diseases, lodging situation and 2019 variety selection test results: Mongolian silage 1812,Beinong silage 368, Mongolian silage 266 are high-yielding and stable. It is recommended to be used in production,and other varieties need to be further tested and demonstrated.
