地膜玉米分带轮作系指在玉米覆膜种植的基础上，通过预留空行，分带间套一季或多季互利互惠的矮秆粮经作物，组成一定复合群体，充分利用作物之间的时间、空间差和生物因素，年度合理进行带内轮换，平衡肥力供应提高地膜玉米生产整体水平的种植制度。笔者自１９８７年开始，在总结单项技术试验研究的基础上，着手研究分带轮作套种马铃薯、豆类和光叶紫花苕的养用结合技术，以玉米高产高效栽培为目标，从耕作、播种、施肥等方面进行了产量效应，增产原因和经济效益分析，结合选用对路高产良种，配方施肥，适时茬口衔接合理田间配置四项关键技术，形成了高寒山区地膜玉米高产高效种植模式。
Membrane corn splinter wheel refers to the film on the basis of corn planting, by setting aside blank lines, set off one quarter or more seasons of mutual benefit reciprocal dwarf grain crops, to form a complex group, make full use of crop Time, space and biological factors, the annual reasonable rotation with the band, the balance of fertility supply to improve the overall level of plastic mulching cultivation system. Starting from 1987, based on the summary of individual technical experiments and studies, the author started to study the combination of cutting and rotation of potatoes, legumes and Haliotis diversicolor with the aim of high yield and high efficiency cultivation of corn. From planting, sowing, fertilizing And other aspects of the yield effect, the reasons for the increase in production and economic efficiency analysis, combined with the selection of high yielding varieties of roads, fertilization, timely stubble junction four rational allocation of key technologies to form a high-mountain mulberry high yield and high efficiency planting mode.
