摘要
在新疆生产建设兵团71团,通过实施玉米密植高产全程机械化绿色生产技术,2014年创造万亩(700hm^2)18 414.0kg/hm^2(1 227.6kg/亩)的全国玉米大面积高产纪录,2017年单产达到18 447.0kg/hm^2(1 229.8kg/亩)。成本效益分析表明,2014年和2017年高产纪录田块净利润分别达到24 118.20元/hm^2(1 607.88元/亩)和16 659.75元/hm^2(1 110.65元/亩),实现了高产高效的协同。技术分析表明,高产田融合了以子粒收获为核心的全程机械化生产技术,以密植栽培、高质量群体调控为核心的高产栽培技术,以绿色防控、秸秆还田、肥料减施为重点的绿色生产技术,通过规模化、标准化生产和统一作业管理,实现了玉米绿色增产增效,为玉米生产转方式增效益和发展现代玉米生产树立了成功案例。
The analysis of technology and benefit in maize field of large area high yield record of 71th farm in Xinjiang Production and Construction Crops shows： National maize 700hm2 large-area high yield record with yield of 18 414.0 kg/hm2 （1 227.6kg/mu） were created in 2014, and net profit reached 24 118.20 yuan/hm2 （1 607.88 yuan/ mu）; yield reached 18 447.0kg/hm2 （1 229.8kg/mu） in 2017, as well as net profit reached 16 659.75yuan/hm2 （1 110.65 yuan/mu）, which realized maize high-yield and high-efficiency cooperation promotion. Compared with traditional production, high yield maize combined full mechanization production technology with core of grain mechanical harvest, high yield cultivation techniques with core of high-density population planting, high-quality group regulation, and green production technology with focus of green prevention and control, straw returning, fertilizer reduction, maize green increase of yield and efficiency was achieved through the large-scale, standardized production and unified operations management, which setted up a succeeded case for modem maize production.
