本研究着重探讨两熟玉米超高产的数量指标及关键技术。研究表明 ,春玉米采用乳苗地膜移栽 ,秋玉米采用套播 ,增加全年总积温 ,进而选用产量潜力较高的中熟或中晚熟玉米品种 ,在主攻“三苗”的基础上构建高光效群体 ,按照超高产玉米的需肥特性合理施肥 ,加强病虫草害防治 ,减轻灾害损失 ,从而实现两熟玉米超高产 This study focuses on the quantitative indicators and key technologies of the two-crop high yielding maize. The results showed that spring maize was transplanted with mulched maize seedlings and autumn maize with set sowing to increase the total accumulated temperature in the whole year. Then, medium-maturing or middle-late maturing maize varieties with higher yield potential were selected to build high light based on the main “three seedlings” Effective groups, in accordance with the characteristics of the demand for ultra-high yield corn fertilization reasonable, strengthen the prevention and control of pests and weeds, reduce disaster losses, so as to achieve two high yield of maize
