In order to understand the popularization and utilization efficiency of intelligent and unmanned wheat seeders in farms in Jiangsu Province,and to provide references for the formation of a technical system and application mode of"Unmanned"equipment suitable for the entire process of rice-wheat rotation planting in the field,several typical large farms and small family farms in Jiangsu Province were selected to conduct an investigation on the application status of intelligent wheat seeders.Comparative tests were conducted by using a typical rotary tillage seeder under two operating modes of manual driving and navigation-assistant driving,and analysis of variance was applied on analyzing the fuel economy of the two seeding modes.The results of analysis of variance in farm investigation and testing experiments indicated that the wide application of linear navigation-assistant driving technology was mainly reflected in intelligent and unmanned farm seeding,and differences in driving modes had no significant impact on fuel economy.The main factors affecting fuel economy were throttle opening and speed of the tractor.Compared to manual driving mode,linear navigation-assistant driving mode can effectively reduce missed and replayed rates of seeding,decreasing from 2%-5% to less than 0.1% .
