Description

TECHNICAL FIELD

[0001] The utility model relates to aquatic plant collection tool technical field, concretely relates to a portable submerged plant field collection device. BACKGROUND

[0002] Submerged plants are primary producers in freshwater ecosystems, and their biomass and diversity are important parameters for evaluating the health and stability of aquatic ecosystems. Sampling and monitoring submerged plants is the most basic and commonly used method in limnology, ecology, and ecological restoration.

[0003] Because submerged plants need sufficient light intensity for growth, they are usually distributed underwater with a water depth of no more than 5 meters. Common submerged plants can be divided into rosette type (cattail), canopy type (fox tailweed, potamogeton), benthic type (chara), and upright type (black algae, elodea) according to their growth type. The stems of rosette type submerged plants are extremely shortened, and they usually reproduce through clonal growth. The plants are dense, the root systems and creeping stems are distributed alternately, the roots are deep, and a dense underwater meadow is formed, making it relatively difficult to collect. Other types of submerged plants usually have developed stems and leaves, and relatively undeveloped root systems, making them relatively easy to collect.

[0004] Currently, commonly used submerged plant sampling and collecting devices generally include grab type, gripper type, net type, iron snip type, and rotary knife type, which are basically variants of the Peterson mud sampler. Most of these grass collecting devices are heavy, have large volumes or lengths, and are expensive. During towing, they can easily damage the integrity of the roots and stems, directly affecting subsequent experiments. Especially in water areas with hard substrates such as gravel and construction waste, the above devices are almost impossible to operate. SUMMARY
