The system application experiment has been carried out in the 800-mu experimental field in Changge county, Xuchang City in June 2015. The experimental results show that the measurement error of this system is less than 5% and could satisfy the actual demand of the real-time wheat yield measuring. The popularization and application of the system would provide the data reference for the wheat yield measuring in
