If the value of the water level detection information is smaller than a predetermined value based on the water level information of the control program by comparing the water level detection information within the water field, the water supply control valve 5 provided at the water supply port of the paddy field 3 is opened to open the water field. The water supply control valve 5 is closed until the water level of the paddy field 3 reaches a predetermined value according to the water level information of the control program, and the water supply control valve 5 is closed when the water level of the paddy field 3 reaches the predetermined value. The operation can be automatically controlled by a control program input to the control personal computer 4, and the water level in the paddy field 3 is automatically set to a predetermined value without water supply from the water supply port as in the conventional case. The water level can be automatically controlled so that the water level quickly reaches a predetermined value even if the water level suddenly drops without spending a great deal of effort on water level management. 3 can always be maintained in an optimum state by automatic control by a computer, and when the value of the water level detection information is larger than a predetermined value according to the water level information of the control program, the water outlet in the paddy field 3 The drainage control valve 6 provided is opened to drain water until the water level of the paddy field 3 reaches a predetermined value according to the water level information of the control program, and the drainage control valve 6 is closed when the water level of the paddy field 3 reaches the predetermined value. Therefore, the opening / closing operation of the drainage control valve 6 can be automatically controlled by the control program input to the control personal computer 4, and the drainage control valve 6 can be automatically controlled without manually draining from the drainage port as in the related art. Water The water level in 3 can be managed to be a predetermined value, and the water level can be automatically adjusted to a predetermined value even if the water level suddenly increases without spending a great deal of effort on water level management. The water level in the paddy field 3 can be constantly maintained in an optimum state by automatic control by a computer.

The water supply control valve 5 is opened and water is supplied to the paddy field 3 when the water level in the paddy field 3 becomes equal to or lower than the lower and lower water level. When the water level reaches the upper limit water level, the water supply control valve 5 is closed, so that the upper limit water level (corresponding to the upper upper limit water level of the present invention) and the lower limit water level (corresponding to the upper limit water level of the present invention) are respectively raised and lowered around the optimum water level as in the related art. (Equivalent to the lower limit water level of the present invention), and water is supplied when the water level of the paddy field reaches the lower limit water level, and the water supply is stopped when approaching the upper limit water level. Water supply After sealed, will soon reach the upper limit water level water level water level rises due to rain, after the water supply,
Although the situation is that water is drained immediately, the amount of water supplied from the irrigation water increases, and the water in the paddy field is drained more than necessary, and it is not possible to save water for the irrigation water and use it efficiently. In the present invention, the water supply control valve 5 is closed when the water level in the paddy field 3 reaches the upper limit water level instead of the upper upper limit water level. Therefore, even if rain falls during the water supply, the water level rises immediately. Without reaching the upper water level,
After the water supply, there is no immediate drainage, the water from the water is not used more than necessary, and the water in the paddy field 3 is not drained more than necessary. And water can be efficiently used.

る。Further, when the water level in the paddy field 3 reaches the upper upper limit water level, the drain control valve 6 is opened to drain the water in the paddy field 3,
Since the drainage control valve 6 is closed when the water level in the paddy field 3 reaches the lower limit water level, the upper and lower water levels are respectively set up and down around the optimum water level as in the prior art, and the water level of the paddy field is set. Drains when the water reaches the upper limit water level, compared to the case where the drainage is stopped when approaching the lower water level, for example, if the clear weather continues at the time of drainage, after stopping the drainage,
The water level immediately drops due to the dry weather and the water level reaches the lower limit, and the water is immediately supplied after draining.The amount of water discharged from the paddy field increases, and the water supply from the irrigation water increases more than necessary. However, the water cannot be used efficiently by saving water, but in the present invention, the drainage control valve 6 is closed when the water level in the paddy field 3 reaches the lower limit water level instead of the lower lower limit water level. For example, even if clear weather continues at the time of drainage, the water level does not immediately reach the lower lower limit water level, and after drainage, the situation of immediate water supply does not occur,
Without using more water than necessary from the water supply,
The water in the paddy field 3 is not drained more than necessary, and the water for use can be saved and used efficiently.

に悪影響を与える要因を少なくすることができる。Therefore, even when the water level in the paddy field 3 fluctuates rapidly, the opening and closing of the water supply control valve 5 and the drainage control valve 6 can be minimized, and the water level can be set to the upper limit value (upper limit). The opening and closing of the water supply control valve 5 or the drainage control valve 6 can be automatically controlled quickly without exceeding the lower limit value (lower and lower limit water level) or the lower limit value (lower and lower limit water level). By minimizing the frequency of opening and closing of the paddy, the supply and stop of water into the paddy 3 and the discharge and stop of water from the paddy 3 can be controlled in a very stable state. It is possible to eliminate the frequent occurrence of the movement of water in 3, and to alleviate the mechanical impact of the water flow caused by the movement of the water on the rice, thereby reducing the factors that adversely affect the growth of the rice.

果的な節水をすることができる。Further, by minimizing the frequency of opening and closing of the water supply control valve 5 and the drainage control valve 6, the amount of water drained from the drainage port can be minimized, and water is supplied from the water supply port. Since the amount of water can be reduced to the minimum necessary and water can be saved and used without wasting water, use this system in recent years when chronic water shortages are occurring. By doing so, you can save water very effectively.

な水位に維持することができる。The upper and lower water levels are set at the upper and lower water level limits, in order to grow rice satisfactorily, that if the water level exceeds this level, the growth of the rice plants will be adversely affected. Was set at the lower limit of the water level, which would adversely affect the growth of rice, if the water level was lower than this, in order to grow rice well, so the water level of paddy field 3 was always the upper limit and lower limit. Since the water level is controlled to a value between these values, the water level of the paddy field 3 can always be maintained at a water level favorable for the growth of paddy rice.

ができる。Further, when the water is supplied to the paddy field 3, the upper limit water level is set in consideration of a water level difference from the upper upper limit water level such that the water level does not immediately reach the upper upper limit water level even if light rain falls. Set the water level and set the lower water level. When draining the water from the paddy field 3, consider the water level difference from the lower and lower water levels that the water level does not reach the lower and lower water levels immediately due to normal dry conditions such as sunny weather. To set the lower limit water level.
It is not necessary to frequently open and close the drainage control valve 6, and it is possible to control the supply and stop of water into the paddy field 3 and the discharge and stoppage of water from the paddy field 3 in a very stable state. 3 can be controlled so that the movement of the water within 3 does not occur frequently.
