specific Embodiment approach 1

[0013] Specific implementation mode one: combine figure 1 Describe this embodiment, a kind of device of controlling paddy field surface water depth of this embodiment comprises first conduit 1, connecting elbow 2, second conduit 3, valve 4 and screen cloth 5, connects one end of elbow 2 and first conduit 1 The lower end of the connecting elbow 2 is connected and fixed, and the other end of the connecting elbow 2 is connected and fixed with one end of the second conduit 3. The first conduit 1 and the second conduit 3 are vertically arranged, and the valve 4 is arranged on the other end of the second conduit 3. The net 5 surrounds the upper end of the first conduit 1 along the circumference of the first conduit 1 , the lower end of the screen 5 is affixed to the side wall of the first conduit 1 , and the upper end of the screen 5 is higher than the upper surface of the first conduit 1 .

specific Embodiment approach 2

[0014] Specific implementation mode two: combination figure 1 The present embodiment will be described. The length h1 of the first catheter 1 of the present embodiment is 4 cm to 12 cm. Such setting can adjust the height of the first conduit 1 located above the soil of the paddy field according to the different requirements for water injection depth in different growth stages of rice, so as to meet the needs of different growth stages of rice. Other components and connections are the same as those in the first embodiment.

specific Embodiment approach 3

[0015] Specific implementation mode three: combination figure 1 The present embodiment will be described. The length h1 of the first conduit 1 of the present embodiment is 5 cm. Usually, the early and late stages of the rice growth period require low water depth on the surface of the paddy field. Taking the water depth requirement of 4cm as an example, it is enough to bury the lower end of the first conduit 1 in the soil at this time, so that the device can be easily buried in the soil. . Other components and connections are the same as those in the second embodiment.

Abstract

The invention discloses a device for controlling the paddy field surface-water depth, and relates to a water depth controlling device. The problems that the paddy field surface-water depth is controlled mainly through a water pump or a small measuring weir at present, the cost of the water pump or the small measuring weir is high, and time and labor are wasted are solved. The device comprises a first guide pipe, a connecting bend, a second guide pipe, a valve and a screen cloth. One end of the connecting bend is communicated and fixedly connected with the lower end of the first guide pipe, and the other end of the connecting bend is communicated and fixedly connected with one end of the second guide pipe. The first guide pipe and the second guide pipe are perpendicularly arranged. The valve is arranged at the other end of the second guide pipe. The upper end of the first guide pipe is wrapped by the screen cloth in the peripheral direction of the first guide pipe. The lower end of the screen cloth is fixedly connected with the side wall of the first guide pipe. The upper end of the screen cloth is higher than the upper surface of the first guide pipe. The device is used for paddy field control irrigation.

Description

technical field [0001] The invention relates to a device for controlling the surface water depth of a paddy field, belonging to the technical field of paddy field control irrigation. Background technique [0002] Controlled irrigation of rice means that after the seedlings are transplanted in the field, the field surface maintains a thin water layer of 5 to 25mm to turn green. After turning green, at each growth stage, the field surface no longer establishes a water layer after irrigation, and the soil moisture in the root layer is used as a control index to determine the irrigation time. and irrigation water. Reasonable soil moisture regulation and control can not only reduce the frequency of irrigation and the amount of irrigation water, greatly save water, but also promote the growth of rice root system, control the invalid growth of rice upper surface, improve the effectiveness of water and fertilizer utilization, and achieve water saving high-yielding purpose. The con...
