青贮玉米收获需求先进的产品青贮玉米收获作业具有单位产量高、收获量大,收获作业周期短,对作业质量要求高等特点。因此决定了设备负荷大,同时收获作业设备的生产率发挥受配套设备和设施很大制约。1 978年开始,我国批量引进东德前进农机公司的E28 1型自走式青贮饲料收获机,在青贮饲料收获作业中发挥了很大的作用;在当时的社会条件下,无论是对设备本身的技术水平,还是对青贮收获作业的配套条 Silage corn harvesting demand for advanced products Silage corn harvesting operations with high unit yield, large harvest, harvesting cycle is short, demanding high quality operations. Therefore decided the equipment load is big, at the same time harvests the productivity of the operation equipment to exert greatly by the accessory equipment and the facility restriction. Since 1978, China’s E28 1 self-propelled silage harvester, which introduced bulk agricultural machinery from East Germany forward, has played a significant role in silage harvesting operations. Under the prevailing social conditions, both the equipment itself The technical level, or silage harvesting operations supporting the article
