As the number of seeds gradually increases, when the seed weight increases to the upper preset value, the pressure sensor 221 below the quantitative plate 23 transmits the data to the external terminal, which receives the data and controls the electromagnetic valve 214 on the front side of the quantitative plate 23. Close, thereby stopping the delivery of seeds and completing the seed replenishment. When the amount of fertilizer is less than the lower limit preset value, the pressure sensor 221 under the quantitative plate 25 transmits data to the external terminal, and the external terminal receives the data and controls the solenoid valve 214 on the rear side of the quantitative plate 25 to open, so that the fertilizer that falls from the feed hopper 29 into the hollow material guide plate 212 is discharged to the rear side of the quantitative plate 25 through the conduit 213.
