摘　　要：玉米对生种子超高产栽培技术研究受到重视。与其配套的2BFM-2型免耕播种施肥机借鉴了国内外典型免耕播种机的经验,结合辽宁西部半旱作区的特点及农艺要求,较好地解决了机具的结构与性能、成本与功能之间的矛盾,可一次完成灭茬、开沟、施肥、播种、镇压及覆土多道工序。Cultivation technology of oppositifolious maize seed with high .,ield is paid attention to, and then, the 2BQD-2 type oppositifolious maize pneumatic fertilizer-and-seeder benefited from the successful experience at home and abroad is designed. It can resolve the contradiction between structure and equipment performance, cost and function associated with the characteristics and agronomic requirements of semi-dry regions in western Liaoning, and complete the following technologies such as breaking stubble, ditching,fertilizing, seeding and turning the soil can be performed in a run.
