Control, to cause opening and closing shutter part 49 to automatically turn off.
Spreading amount adjustment unit 50 is configured to：Whether each grid that directing fertilization spirogram table 5 can be stored completes fertilizer
Spreading information, when body 31 again from the grid of the spreading for completing fertilizer by when, can be automatically controlled so that
It must measure that gate part 48 is automatically completely closed or so that opening and closing shutter part 49 is automatically turned off.
It is configured to that following pattern can be switched over：Enter to exercise spreading amount in part based on dose chart 5
The pattern (the spreading pattern based on chart) of the control of change；And the pattern for being not based on dose chart 5 and being dispensed is (logical
Often dispense pattern).
Metering gate part 48 and opening and closing shutter part 49 can be driven by the appropriate actuator beyond electro-motor.
In the above-described embodiment, the data of dose chart 5 are stored in from the PC that the chart has been made it is removable
After formula external memory storage, by by the memory device assigned in helicopter 30 (spreading amount adjustment unit 50) by the dose
The data input of chart 5.However, instead, helicopter 30 can also be (such as logical based on wireless mode using communication unit
Letter portion) data of dose chart 5 are received and inputted from the PC.
