Water level regulating device for paddy field

Abstract

A paddy field water level regulating device 6 installed between a water pipe buried along a farm road 43 and a farming plot 42, the device consisting of a cylindrical feed and drain basin 60 with a closed bottom, having a farming plot feed and drain port 61 communicating with the farming plot 42; a water inflow and drain section located in the feed and drain basin 60 near the bottom thereof and connected to the water pipe; a drain valve located in the water inflow and drain section; and a height-adjustable water level regulating weir 65 located in and water inflow and drain section.

Description

technical field [0001] The present invention relates to a paddy field water level regulating device, more specifically, it is about being able to easily adjust the field surface water level of each cultivated area in the paddy field to the desired height with the necessary minimum water consumption, and to easily carry out water level adjustment. The paddy field water level regulating device for supply or discharge. Background technique [0002] The paddy field of prior art has Figure 31 The structure shown in the floor plan. That is, the water flowing through the river 1 is introduced from the waterway 21 to the main water supply channel 30 and supplied to the paddy fields 4 . The paddy field 4 is divided into several farming areas 42 by ridges 41 . On the side edge of the agricultural road 40 extending along the length direction of the paddy field 4 , open water supply channels 31 are provided along the respective cultivation areas 42 . The upstream side of this water ...

Problems solved by technology

In this way, the water is sequentially supplied from the cultivation area 42 on the upstream side to the cultivation area 42 on the downstream side, resulting in insufficient supply of the appropriate amount of water to the cultivation area 42 on the downstream side.

Especially in the dry period of continuous sunshine, it is basically impossible to supply water to the cultivation area 42 on the downstream side, resulting in poor growth of rice and a decrease in harvest.

[0005] In addition, each waterway is made the paddy field of the prior art of open type, because water supply road 31 and drainage road 33 occupy certain width, make the space of cultivation area 42 and agricultural road 40 narrow, have brought the problem that can not utilize land effectively question

Furthermore, sand and the like are easily accumulated in the waterways that are open upward, and sand and the like must be frequently discharged, which complicates the management of the waterways.
