Abstract

The application discloses a marine plant photosynthetic capacity analysis device, which is applied to the technical field of marine ecological monitoring devices and comprises a photosynthesis chamber and an oxygen excretion chamber, a shared partition plate, a through hole of the partition plate, a first water isolation component, a second water isolation component, a leaf part, a root part, a light source, a heating device, a water inlet, a liquid inlet, a seawater supply pipeline, a salinity adjusting liquid supply pipeline and a pH adjusting liquid supply pipeline, and a detection device and a control device. Before the photosynthetic capacity of the plant is determined, the control device is configured to control the light source, the heating device, the water inlet and / or the liquid inlet so that the environmental parameters are restored to a preset range. The accuracy of the determination of the photosynthetic capacity of the marine plant is improved.
