In situ culture systems and methods of use thereof

Abstract

The invention provides an in-situ cultivation system and an application method thereof. The in-situ cultivation system comprises a mechanical structural frame and an electronic-control processing module. The mechanical structural frame comprises a cultivation vessel device, a liquid sample collection device and a lifting device; the electronic-control processing module comprises a power supply module, a processor module, a direct-current motor circuit module and a stepping motor circuit module. The liquid sample collection device comprises an injection device, a sampling device, a console, a measurement sensor, a control side panel, a stepping motor, a driving belt, a rolling bar, movable bars and the like. The in-situ cultivation system is applied to seabed water oxygen consumption process, is integrated with the electronic-control module, a motor, a vessel, a seawater measurement sensor and other mechanical modules, and descends to the seabed by gravity; a closed space is formed by the vessel and the seabed sediment interface; the measurement sensor in the vessel measures data of dissolved oxygen and environmental parameters continuously, and meanwhile, the measurement sensor arranged out of the vessel measures data of external water dissolved oxygen and environmental parameter continuously.

Description

Technical field [0001] The invention relates to the technical field of seabed water body detection, in particular to an in-situ culture system in the process of oxygen consumption and a use method thereof. Background technique [0002] The rapid economic development of the Yangtze River Basin in recent decades has increased the concentration of various nutrients carried by the Yangtze River dozens of times, making the eutrophication of the Yangtze River Estuary waters higher and higher. The eutrophication of the water body has changed the structure of the productivity of the sea area, leading to frequent and large-scale outbreaks of red tides, which in turn caused the normalization of hypoxia in the bottom water body in summer, posing a threat to the fisheries in the East my country Sea, and therefore hypoxia in the bottom water body of the Yangtze River Estuary Process monitoring, research and status evaluation are of great significance. The seasonal large-face station survey of...

AI Technical Summary

Problems solved by technology

Due to the weak foundation and late start of marine observation technology research in my country, the observation of the oxygen consumption process of organic matter in seabed water is limited to laboratory simulation cultivation experiments, and there is a lack of platforms for on-site cultivation experiments.
