A kind of control paddy field surface-water depth device
Technical field
The present invention relates to a kind of control paddy field surface-water depth devices, belong to paddy field control irrigation technique field.
Background technique
Rice control, which is irrigated, to be referred to after the transplanting of rice shoot Honda, and field face keeps 5~25mm thin water layer to turn green, each after turning green
A growing stage, field face does not resettle water layer after pouring water, and using root layer soil moisture as Con trolling index, determines irrigation period and filling
Irrigate water.Reasonable soil moisture adjusts and control, can not only reduce frequency of irrigation and duty, significantly save water
Amount, and Root Growth of Rice can be promoted flourishing, control rice earth's surface top plant type is grown in vain, and raising liquid manure utilizes effective
Property, achieve the purpose that saving irrigation model.And the control of paddy field surface-water depth is the main foundation that control is irrigated.With controlling paddy field at present
The table depth of water mainly passes through water pump or small water-metering weir, and apparatus above is at high cost, time-consuming and laborious.
Summary of the invention
The present invention mainly passes through water pump or small water-metering weir, the above dress to solve existing control paddy field surface-water depth
Problem at high cost, time-consuming and laborious is set, and then proposes a kind of control paddy field surface-water depth device.
In order to solve the above-mentioned technical problem the present invention adopts the technical scheme that: a kind of control paddy field surface water of the invention

Specific embodiment one:
It is illustrated in combination with fig. 2, when water filling depth of the rice in entire breeding time needs to control the use in same depth bounds
One apparatus of the present invention can be met the requirements, and for filling the water depth and need to control in 5cm~10cm, the length of the first conduit 1 is selected
11cm is selected, the length of the second conduit 3 selects 60cm, the second conduit 3, connecting bend 2 and 1 lower end 1cm of the first conduit are embedded in
In paddy field soil, paddy field 7 is stretched out to the direction of checkdam 9 in one end with valve 4 of the second conduit 3, and the first conduit 1 is located at soil
The height h4 of top is 10cm, elbow firm banking 10 can be used to support the present apparatus during landfill, prevents the present apparatus from using
When tilt or mobile, can be in the outer surface reference mark of the first conduit 1 for the ease of observing the depth of water, can also be by a graduated scale 6
It is inserted vertically into the soil on 1 side of the first conduit, opens valve 4 and inject water 8 into paddy field, there are flowing out when in the second conduit 3
When, show that filling the water depth reaches 10cm, stops irrigating at this time immediately, closes valve 4, monitors water surface site using graduated scale 6, when
When water surface elevation has dropped 5cm, valve 4 is opened, continues to irrigate, until the second conduit 3 there are flowing out again, stopping is irrigated, and is closed
Valve closing door 4 repeats above-mentioned work, can be by water level control in 5cm~10cm.
Specific embodiment two:
Illustrate in conjunction with Fig. 3, when rice needs to control in two different depth bounds in the water filling depth of entire breeding time
When, then it needs simultaneously using two apparatus of the present invention, i.e. device A and device B, it is deep with the early period of growth period duration of rice and latter stage water filling
Degree need to be controlled in 0cm~4cm, and the mid-term water filling depth of growth period duration of rice need to control for 5cm~10cm, by apparatus of the present invention
A and B is placed in paddy field simultaneously, and the length of the first conduit 1 of device A selects 4cm, the length selection of the first conduit 1 of device B
The length of the second conduit 3 of 10cm, device A and device B selects 80cm, by the second conduit 3 of device A and device B and connection
Elbow 2 is embedded in paddy field soil, and make device A and device B the second conduit 3 one end with valve 4 to checkdam 9
Paddy field 7 is stretched out in direction, and it is 4cm that the first conduit 1 of device A, which is located at the height above soil, and the first conduit 1 of device B is located at soil
Height above earth is 10cm, and two elbow firm bankings 10 can be used to distinguish support device A and device B during landfill, is prevented
Only they are tilted when in use or movement is for the ease of observing the depth of water to be inserted vertically into device A and device B for a graduated scale 6
Between soil in, when rice is in early period breeding time, close the valve 4 on device B, the valve 4 on device for opening A, to
Water 8 is injected in paddy field, when there are flowing out in the second conduit 3 of device A, shows that filling the water depth reaches 4cm, stops immediately at this time
It irrigates, closes the valve 4 of device A, monitor water surface site, when water surface elevation has dropped 4cm, device for opening A using graduated scale 6
Valve 4, continue to irrigate, until the second conduit 3 of device A there are flowing out again, stop irrigating, close the valve 4 of device A,
Above-mentioned work is repeated, it can be by water level control in 0cm~4cm;When rice is in breeding time mid-term, the valve on device A is closed
Door 4, the valve 4 on device for opening B inject water 8 into paddy field and show to infuse when there are flowing out in the second conduit 3 of device B
Water depth reaches 10cm, stops irrigating at this time immediately, closes the valve 4 of device B, monitors water surface site using graduated scale 6, works as water
When having dropped 5cm, the valve 4 of device for opening B continues to irrigate face height, until the second conduit 3 of device B there are flowing out again,
Stop irrigating, close the valve 4 of device B, repeats above-mentioned work, it can be by water level control in 5cm~10cm;When rice is in life
When educating the phase in the end of term, the valve 4 on device B is closed, the valve 4 on device for opening A has water flow in the second conduit 3 of device A at this time
Out, when the second conduit 3 of device A stops flowing water, water 8 is injected into paddy field, when having water again in the second conduit 3 of device A
When outflow, show that filling the water depth reaches 4cm, is stopped irrigating at this time immediately, closes the valve 4 of device A, monitored using graduated scale 6
Water surface site, when water surface elevation has dropped 4cm, the valve 4 of device for opening A continues to irrigate, until the second conduit 3 of device A
It there are flowing out, stop irrigating, close the valve 4 of device A, repeat above-mentioned work, it can be by water level control in 0cm~4cm.
