Quantitative sampler for macrophytes

Abstract

The invention discloses a quantitative sampler for macrophytes. A using method comprises the following steps of: allowing a user to stand on a sampling boat during sampling, and sleeving eight directional bending pipes and a bending pipe with a blade into two sliding quadrat frames which are parallel to the water surface and keep a certain distance (more than or equal to 5cm) from each other; extending the eight directional bending pipes and the bending pipe with the blade to the bottom of a lake, upwards pulling T-shaped solid connecting rods in the directional bending pipes, and clamping clamp handles of the T-shaped connecting rods on the outer edges of steel pipes with hollow upper parts; upwards pulling a I-shaped connecting rod, clamping a clamp handle of the I-shaped connecting rod on a bendable sheet, and rotating the I-shaped connecting rod 360 degrees; and finally, upwards pulling a rope handle to lift the device, cutting off samples which are positioned outside the slidable quadrat frames by using scissors, and collecting aquatic plant samples in quadrats. The device can solve the problem that the ordinary sampler cannot take samples in spreading and expansion areas of the macrophytes, has a simple structure, is convenient to assemble and easy to operate, is low in cost, and can ensure the accuracy of sampling areas.

Description

technical field [0001] The invention relates to a quantitative sampler for large aquatic plants, which is especially suitable for sampling the submerged plants in lakes where the large aquatic plants grow luxuriantly and spread into sheets. Background technique [0002] Macrophytes are all aquatic plant groups except microalgae. They are an important part of aquatic ecosystems and play an important role in maintaining the balance and stability of aquatic ecosystems. [0003] For the study of lake aquatic plant community structure and its biomass, the operability and simplicity of quantitative sampling of aquatic plants are often involved. At present, the quantitative collection of large aquatic plants is mainly carried out by iron clip sampler with net. The depth is about 90cm. When the iron clip is fully opened, the frame opening is a square with an area of ​​0.25m 2 , When sampling, fully open the iron clip, put it into the water, and close the pull-up to collect samples...
