With the development of informatization, China has promoted “Internet+agricultural machinery operation”, which accelerated the promotion of agricultural machinery operation monitoring and the agricultural machinery monitoring & scheduling platform, and improved the quality and efficiency of agricultural machinery operation. Massive data of agricultural machinery operation was accumulated at the same time. In order to research on the relationship between the power of agricultural machinery and agricultural machinery in the process of subsoiling efficiency, the subsoiling operation data in Shandong Province was taken as the research object. In the research, totally 323 tractors installed subsoiling agricultural machinery remote intelligent monitoring terminal were selected as analysis samples (produced by Foton Lovol Corporation). The experiment data included 37981 sets about the operation area, duration of the operation and efficiency of agricultural machinery operation from April 2015 to April 2017. The agricultural machinery power range was from 52.20kW to 197.61kW. All the experiment data were divided into two parts: calibration set (80%) and validation set (20%) by sampling without replacement method. The agricultural machinery subsoiling efficiency model was established based on agricultural machinery power. The correlation coefficient between agricultural machinery power and subsoiling operation efficiency was 0.9147, and RMSE was 0.1684hm2/h. The RMSE of validation set was 0.3396hm2/h. The agricultural machinery subsoiling efficiency model provided a new method for agricultural machinery service organization to allocate agricultural machinery and assign tasks reasonably.
