Abstract: Focusing on the whole-process mechanization of soybean and corn strip compound planting, management and harvesting, using the special machines and tools for synchronous operation such as soybean and corn integrated seeder, synchronous belt spray rod sprayer, soybean and corn integrated harvester, as well as the stepwise applicable machines and tools such as high-clearance corn harvester and small narrow-range harvester as research object, depending on the development of test and application situation in recent years, this paper deeply analysises and summaries the technical characteristics, research and development production, test verification, application and points for attention, mastering the special machinery development present situation, improve the operating efficiency, operation quality, adaptability and key structure clearly machinery research and development trend, for soybean corn belt compound planting whole-coursing mechanization development lay the foundation. Centering on the improvement of ripening and popularization of machinery and tools, suggestions were put forward from the aspects of selection and breeding of simultaneous sowing and simultaneous ripening varieties, research on key technologies, formulation of identification and evaluation methods, selection of applicable machinery and tools models, experimental demonstration and popularization, and consolidation of whole-process mechanization modes.
