Abstract

The invention provides experimental apparatus, system and method for aquatic plants. The experimental apparatus for aquatic plants comprises an experimental cylinder, at least two rotating mechanisms, and at least two sampling guide tubes, wherein the experimental cylinder is used for holding water and aquatic plants. The rotating mechanisms are disposed in the experimental cylinder in different depths. The sampling guide tubes are disposed in the experimental cylinder in different depths. The experimental apparatus has the advantages that original water serves as the experimental environment, a fan is used to power the water to flow, and accordingly the influence of waterflow speed upon growth of the aquatic plants can be researched in the original water at controllable flow speed.

Description

technical field [0001] The invention relates to the experimental field of aquatic plants, in particular to an experimental device, an experimental system and an experimental method for aquatic plants. Background technique [0002] In recent years, with the deepening understanding of the nutrient cycle mechanism, many scholars have begun to analyze the influencing factors of water eutrophication by studying the flow state of water bodies. [0003] Taking algae as an example, the current research and test methods for the influence of hydrodynamic conditions on algae are mainly: on-site observation, measuring the flow, flow velocity, water quality and water environment indicators of the river section during the occurrence of algae blooms, and establishing the relationship between the flow velocity and the concentration of chlorophyll a. Relational formula to analyze the effect of flow rate on algae growth. This method is difficult to study the growth of algae under different f...
