农业机器的更新换代目前已成为农业机械化软件研究领域中不可忽视的问题。特别是随着垦区经济管理体制的改革,家庭农场的普及,农业机器的报废更新就直接影响到农户或家庭农场主的切身经济利益。因此,研究机器更新的着眼点应由宏观更新的研究转向针对具体机器的微观更新研究。 The replacement of agricultural machinery has become a problem that cannot be ignored in the field of agricultural mechanization software research. In particular, with the reform of the economic management system in the district, the popularity of family farms, and the retirement of agricultural machinery directly affect the immediate economic interests of farmers or family farmers. Therefore, the focus of research on machine renewal should be changed from macro-update research to micro-update research on specific machines.
