为了探索京郊玉米生产全程机械化轻简栽培经济技术可行性,设置了应用2BYFJ型玉米多功能精位播种机单粒播种和传统普通播种机播种对照试验,检验玉米单粒精量播种技术轻简节本、增产增效的功效。试验选用生育期、产量水平相同的京科968和郑单958两个作为供试品种,以适应不同播种方式播种、出苗需求。试验结果显示:采取单粒精量播种的京科968产量为678.9 kg/667 m2,经济效益为905.8元/667 m2,采用普通播种机播种的郑单958产量为627.6 kg/667 m2,经济效益为752.8元/667 m2,单粒精量播种技术比传统技术产量增51.3kg/667 m2,经济效益增153元/667 m2。
In order to explore the economical and technical feasibility of mechanization and light-weight cultivation in the whole process of corn production in Beijing suburb, a single-grain sowing trial of 2BYFJ corn multi-function precision sowing machine and a conventional sowing machine were used to test the sowing precision of single grain sowing of corn Festival, the effect of increasing production and efficiency. Test selection growth stage, the same level of production Jingke 968 and Zhengdan 958 two as tested varieties to adapt to different sowing methods of seeding, emergence needs. The results showed that the output of Jingke 968 was 678.9 kg / 667 m2 with the economic benefit of 905.8 yuan / 667 m2 and the output of Zhengdan 958 was 627.6 kg / 667 m2 with the sowing machine. The economic benefit For 752.8 yuan / 667 m2, a single precision sowing technology than the traditional output by 51.3kg / 667 m2, economic benefits by 153 yuan / 667 m2.
