That is, the water amount adjustment control device 265 calculates the amount of water in the farmland based on the detected values of the first water amount sensor 253 and the second water amount sensor 258, and compares the calculated water amount with respect to the first opening and closing device 252 and the second opening and closing device. By controlling 257, water can be introduced from the waterway 260 to the farmland or the water in the farmland can be discharged to the waterway 260.

The water amount adjustment control device 265 calculates the amount of water in the farmland based on the detected value of the first water amount sensor 253 and the average value of the detected value of the second water amount sensor 258, and makes the first opening and closing device more or less in comparison with the calculated amount of water. 252 and the second opening and closing device 257 work to make the water intake gate 251 and the drainage gate 256 open and close, adjust the amount of water in the farmland. Thereby, the amount of water in the farmland becomes the amount of water suitable for crop cultivation.
