For preventing from fertilizer excessively operated and no operated during seeding,the paper studied the real-time test weight of fertilizer operated by precision seeder.Real-time weight of fertilizer operated was indirectly measured,optical-electrical sensors were used to monitor fertilizer spout jammed and fertilizer exhausted.The system was experimented in farm,its testing errors were smaller than 9.8%.It had some characters,such as cheap cost,better test accuracy and real-time,and easy installation.
