我国从６０年代开始研制甘蔗收割机和甘蔗剥叶机，由于多方面的原因，进展缓慢，直至７０年代中期才有大规模的研究活动，目前，除了耕整地外大多数仍依赖人畜作业，劳动费用在生产成本中占了最大的比重。因此，采用机械化生产是降低甘蔗生产成本的关键所在。１我国甘蔗生产? Since the 1960s, China began to develop sugarcane harvesters and sugar cane leaf-peeling machines. Due to various reasons, the progress was slow. There was no large-scale research activities until the mid-1970s. At present, most of the cultivated land except for cultivated land still relies on human and livestock operations and labor Costs account for the largest share of production costs. Therefore, using mechanized production is the key to reducing the cost of sugar cane production. 1  China’s sugar cane production?
