Abstract: Precision sowing can effectively reduce the number of seeds used, save costs and money, and the quality of crops grown through precision sowing is high. In order to grasp the development level of electronically controlled precision sowing technology at home and abroad, this paper carries out research from precision sowing online detection technology, sowing volume control technology and seed replenishment technology, focusing on the advantages and disadvantages of photoelectric sensor detection, piezoelectric sensor detection, capacitive sensor detection, visual image detection and precision sowing control technology; and points out the lack of standardization of precision sowing machines in China, insufficient research and development of high precision sensors, and immature intelligent control technology. Finally, combined with the current development situation at home and abroad, the development trend of China’s precision sowing technology in the direction of multi-machine collaboration, remote control and intelligent control is to provide some reference for future researchers to understand electronically controlled precision sowing technology in China.
