specific Embodiment approach 1

[0016] Specific implementation mode one: combine figure 1 Illustrate this embodiment, a kind of pond field experiment device of this embodiment comprises water barrier cloth 2, U-shaped pipe 3, oxygen-increasing aeration device, anti-escape net 5, two filter screens 4, two straight pipes 7, four One vertical rod 8 and four cross rods 9; the four vertical rods 8 are arranged in an array, a cross rod 9 is connected between two adjacent vertical rods 8, and four vertical rods 8 and four cross rods 9 form a square frame;

[0017] The water-proof cloth 2 is arranged on the side of the square frame, and the water-proof cloth 2 and the square frame form a cavity with four sides closed and the upper and lower ends open. One of the arms of the U-shaped pipe 3 passes through the cross bar 9 and is arranged on the In the square frame, the other arm of the U-shaped pipe 3 passes through the cross bar 9 and is arranged outside the square frame. A filter screen 4 is respectively arranged on...

specific Embodiment approach 2

[0019] Specific implementation mode two: combination figure 1 Describe this embodiment, the four vertical bars 8 in this embodiment are galvanized pipes, and the four horizontal bars 9 are bamboo poles.

Abstract

The invention discloses a pond field experimentation device and a using method thereof and relates to a device for experimental study of pond water area ecology and a using method thereof. The problems that the water oxygenation effect is bad, the water inlet and drainage are inconvenient, fishes are difficult to escape and the requirements of experimental study of pond water area ecology cannot be met in the conventional field experimentation enclosure ecosystem are solved. The pond field experimentation device comprises waterproof cloth, a U-shaped pipe, an oxygenation aeration device, an anti-escape net, two filtering nets, two straight pipes, four upright rods and four transverse rods, wherein the four upright rods are arranged in an array; a cross rod is connected between two upright rods; and the four upright rods and four transverse rods form a square frame. The field enclosure experimentation method mainly comprises the following steps: 1, inserting the upright rods on the square frame into the bottom of the pond; 2, injecting water into the square frame with the waterproof cloth; 3, oxygenating and aerating in water; and 4, draining water in the square frame. The pond field experimentation device is used for research of pond water area ecology.

Description

technical field [0001] The invention relates to a device for ecological experiment research of pond water area and a using method thereof, in particular to a pond field experiment device and a using method thereof. Background technique [0002] Field enclosure experiment is a new research method of pond water ecology, and it is also an effective tool for studying pond water ecosystem. The advantages of the enclosure culture system are: first, due to its regular shape and small volume, it has higher controllability than large water bodies; The conditions are more uniform, and the data obtained are more comparable; third, it is small in size, easy to manage, small in scale, and low in use cost, so one experiment can be set up for more treatments and repetitions; fourth, its internal environment The conditions and scale of the water body are closer to that of a pond, so the experimental data is more authentic and representative than the indoor water body. Therefore, experimen...
