通过查阅文献、调查和个人通讯,对水稻生产机械化的发展进行了研究。从中可以知道,发达的工业化国家已全部实行了水稻生产机械化,而在发展中国家,水稻的绝大部分田间作业仍靠手工劳动去完成。但是,一些实用的农业机械亦正在这些国家应用着。日本研制了一些小型动力机械,这些小型动力机械适用于贫穷国家的小规模农场。 Through consulting literature, investigation and personal communication, the development of rice production mechanization has been studied. It can be seen from the fact that the developed industrialized countries have all implemented the mechanization of rice production. In developing countries, most of the paddy field operations are still carried out by hand labor. However, some practical agricultural machinery are also being used in these countries. Japan has developed a number of small power machines that are suitable for small-scale farms in poor countries.
