Abstract: At the present stage, the import of soybean and corn is increasing year by year, and food security has a big hidden trouble. China started the soybean and oil production capacity improvement project, and vigorously promoted the soybean and corn strip compound planting technology. The agronomy of soybean and corn strip compound planting is based on the core of “selecting and matching varieties, expanding and increasing light, shrinking plant strain and retaining density” and the supporting of “reducing integrated fertilization, chemical control and lodging resistance, green prevention and control”. The overall requirements for improving the performance and operational efficiency of agricultural machinery are put forward. In terms of sowing, high-speed precision sowing technology, soybean and corn separate control technology, large-displacement fertilization technology, straw anti-blocking technology and cohesive line uniformity technology were developed. In terms of the field management, the double spray technology, spray rod adaptive leveling technology, plant protection wheel spacing adjustable technology, anti-floating nozzle technology were developed. In terms of harvesting, the development of corn low-loss picking mechanism, corn low-loss and low-break grain harvesting technology, soybean low-loss cutting table technology, soybean low-break flexible threshing technology, soybean efficient cleaning technology, soybean low-loss grain transportation technology, soybean online quality detection technology were also developed. At present, it is necessary to optimize the mechanization equipment in the whole process of soybean and corn strip compound planting, further combine the agronomic characteristics of soybean and corn strip compound planting and the characteristics of operating machinery and tools, strengthen the theoretical research, promote the further integration of agricultural machinery and agronomy, strengthen the research and development of innovative machinery and tools, and improve the adaptability of the machine to the planting mode.
