摘　　要：条播玉米的群体产量取决于玉米单株营养状况,"玉米蜂巢式田间配置高产栽培技术"通过缩小行距增大密度,既能"足群体",又能不缩小玉米单株内切圆营养面积,在"足群体"下"壮个体",具有极显著增产作用。试验田产量测试鉴定及生产示范推广结果均表明:"玉米蜂巢式田间配置高产栽培技术"有助于玉米群体单株均匀受光,有助于田间种植密度提高,具有密植增产、增效等优点,显示出较好开发前景。The key technique, technology index, theoretic foundation of yield increase of Maize Cellular Planting Technique was studied and discussed. The results indicate： The mass yields are dependent on the nutrition situation of maize single plant; to increase density by reducing row space not only is good for ＂ enough tion area of maize single plant suitable for ＂strong single plant＂ under ＂enough density＂ - density＂ but also keeps nutrithis technique has significant high yield effect. The result of yield determination by experiment and extension in production shows that the Maize Cellular Planting Technique is good for single maize plant to absorb sunlight equally under ＂enough density＂, and get high density and it possesses the advantage of close-planting, nutrition improvement, increasing yield and benefit and will be used widely in the future.
