玉米、大豆间作套种是充分利用资源、提高土地产出率的集约农业技术,但在机械收获方面,难度较大。介绍了根据西南丘陵区特点和玉米间套生产特点联合研制的4YZ-2450玉米联合收获机。机具研制成功使玉米—大豆带状间套作全程机械化迈上了新的台阶,实现了西南地区玉米机收零的突破。 Intercropping with corn and soybean is an intensive agricultural technique that makes full use of resources and increases land productivity, but it is more difficult to harvest machinery. The 4YZ-2450 corn combine harvester was developed according to the characteristics of southwest hilly area and the production characteristics of corn. The successful development of the machine made the whole maize-soybean intercropping set a new stage and realized the breakthrough of corn machine in southwest China.
