Underwater plant quadrat collecting device and sampling method thereof

Abstract

The invention discloses an underwater plant quadrat collecting device which comprises a submerged frame, the submerged frame is connected with a hanging wire, the submerged frame comprises a side wall frame body, a bottom plate, a partition plate and a push rod, the side wall frame body is a vertically-through surrounding frame, a vertically-through sampling groove is formed in the position, corresponding to a sampling and cutting area, of the bottom plate, a magnet is fixed to the right side face of the sampling and cutting area, the push rod horizontally penetrates through the partition plate, so that the left end of the push rod is located in the elastic pushing area and the right end of the push rod is located in the mining and cutting area, a head plate is installed at the left end of the push rod, a ferromagnetic plate is installed at the right end of the push rod, a spring is further installed on the push rod, and an operable buckle is arranged in the elastic pushing area and can clamp the head plate, a mounting rack is fixedly arranged over thesubmerged frame, and a waterproof camera and a water pump are mounted on the mounting rack. The underwater plant quadrat collecting device can directly sink into the water bottom, carries out underwater plant quadrat sampling at the water bottom, and is simple in structure and convenient to use.

Description

technical field [0001] The invention relates to the technical field of plant sampling devices, in particular to a collection device for underwater plant sample quadrats and a sampling method thereof. Background technique [0002] Plant quadrat collection is an important part of ecological environment detection and restoration. At present, most plant quadrat collection devices can only be used for terrestrial vegetation, such as the collection of grassland vegetation. However, the detection and restoration of the ecological environment does not simply involve terrestrial vegetation. The ecological detection and restoration of lake water is also a key part of the detection and restoration of the ecological environment. [0003] At present, there is no convenient and simple collection device for underwater plant quadrats, and since most aquatic plants grow at the bottom of shallow lakes, the stones and sediment at the bottom of the lake will increase the difficulty of sampling ...

Problems solved by technology

[0003] At present, there is no convenient and simple collection device for underwater plant quadrats, and since most aquatic plants grow at the bottom of shallow lakes, the stones and sediment at the bottom of the lake will increase the difficulty of sampling when sampling, and aquatic plants will float with the water flow. It is not fixed, and the difficulty of collection is further increased
