To provide a rice paddies intake management device which can realize irrigation in a state with low electric power consumption and little water temperature difference by a simple configuration.SOLUTION: The water intake management device 1 of a paddy field comprises a water stop machine 2 attached to the water intake port 10 for opening and closing the water intake port 10 of the paddy field, a water level gauge 3 for measuring the water level of the paddy field, And a water intake control unit 8 for driving and controlling the water booster 2 on the basis of the output of the water level gauge 3 and the output of the timer 7. The intake control unit 8 starts withdrawing at the start time of the water intake time period, and when the water intake is completed at the end time of the water intake time period and the water level exceeds the predetned value, the water intake is ended even before the water intake end time And drives and controls the opening and closing motor 19 of the water supply water machine 2.(FIG.【課題】電力消費が少なく、かつ、水温差の少ない状態での灌水を、簡単な構成により実現可能な水田の取水管理装置を提供すること。【解決手段】水田の取水管理装置1は、水田の取水口10を開閉するために当該取水口10に取り付けて使用される給止水機2と、水田の水位を計る水位計3と、夜間の所定の時間帯を取水時間帯として設定するタイマー7と、水位計3の出力およびタイマー7の出力に基づき、給止水機2を駆動制御する取水制御部8とを有している。取水制御部8は、取水時間帯の開始時刻に取水が開始し、取水時間帯の終了時刻に取水が終了し、水位が所定値を超えると、取水終了時刻前であっても取水が終了するように、給止水機2の開閉用モータ19を駆動制御する。【選択図】図2
