Utility model content
The purpose of this utility model is to overcome the above-mentioned problems in the prior art, there is provided one kind measurement Crop Evapotranspiration
Amount and the device of Soil percolation, its water collected within a period of time, by measuring tank, obtain making in square container
The transpiration quantity of thing；By measuring square container lower end leaking hole water, Soil percolation is obtained, its simple in construction, operation side
Just it is, cheap.
To realize above-mentioned technical purpose and the technique effect, the utility model is to be achieved through the following technical solutions：
A kind of device for measuring crop evapotranspiration and Soil percolation, including upper lid, square container, foot support, it is described
The approximate positive rectangular pyramid of upper cap-shaped shape, upper caping end are 25cm far from bottom distance, and the bottom square length of side is 50cm, the square
The container length of side is 50cm, and square container head edge is provided with the wide tanks of 5cm, and square container upper end is connected with upper lid, just
Cube container bottom is positive rectangular pyramid convex downwards, and positive rectangular pyramid vertex position is provided with five diameter 1cm leaking hole, summit
Distance away from bottom surface is 15cm, and the foot support connection square container bottom, foot support is highly 30cm.
Preferably, a diameter of 1cm gully-hole is provided with the square container head edge tank.
Preferably, the square container bottom is provided with leakage water collecting device.
The beneficial effects of the utility model are：
1st, the measurement apparatus of crop evapotranspiration and Soil percolation, simple in construction, easy to operation and cost are low
It is honest and clean.
2nd, when measuring the crop evapotranspiration and Soil percolation in a period of time, the water collected by direct measurement tank
Amount, can obtain the transpiration quantity of crop in square container；By measuring water leakage under the leaking hole of square container lower end, can obtain native
Earth leakage；Crop evapotranspiration and Soil percolation are intuitively measured, it is convenient and practical.
Certainly, implement any product of the present utility model to it is not absolutely required to reach all the above advantage simultaneously.
