Abstract: Rice is an important grain crop in China, accounting for about 30% of the planting area of grain crops in China, and plays an irreplaceable role in China’s grain production. The realization of the mechanization of rice production is one of the important contents of agricultural modernization, but at present, China’s mechanized rice planting, transplanting and harvesting technology has certain differences compared with foreign advanced technology. In view of the above problems, this paper systematically discusses the basic technical characteristics and common types of rice cultivation mechanization technology, rice planting mechanization technology, rice fertilization mechanization technology and rice mechanized harvesting technology. The results of this study are intended to provide a theoretical reference for improving the mechanized production technology of rice.
