In-situ seawater nutrition enrichment experiment device and use method thereof

Abstract

The invention discloses an in-situ seawater nutrition enrichment experiment device and a use method thereof. The device comprises an experiment box, a power box is fixed at the top of the experiment box, and a first bin is formed in the power box, wherein the first bin is provided with an electric control module. A partition plate is arranged at the lower end in the experiment box; the experimentbox is divided into a second bin and a third bin through a partition plate. A sample injection module, a pipetting module and an analysis test module are sequentially arranged in the second bin. According to the in-situ seawater nutrition enrichment experiment device, the seawater temperature, illumination and water body fluctuation state are truly simulated, in-situ experiment automation is achieved through the automatic pipetting module and the analysis and test module, and heavy manpower on the sea is saved. The volume and the precision of the moved reagent can be determined according to the model of the injection pump and are preset by the processor, so high-precision reagent addition is realized; culture time can be preset through the processor, reagent types can be changed and added,a plurality of culture bags can be arranged, and the device is suitable for different types of in-situ ecological experiments.

Description

technical field [0001] The invention relates to the technical field of seawater in-situ ecological experiments, in particular to an in-situ seawater nutrient enrichment experiment device and a method for using the same. Background technique [0002] Nutrients are the basis for the survival of algae. Algae in different sea areas have different nutritional needs. Seawater nutrient enrichment experiments are an important means to quantitatively evaluate the nutrient requirements of seawater algae, which is of great significance for seawater ecological cultivation and marine ecological civilization. [0003] At present, the foundation of marine technology in China is weak and started late. Nutrient enrichment experiments are mainly carried out in shore-based laboratory simulations or in culture tanks on board. It is difficult to simulate the actual temperature, light and hydrodynamic conditions of seawater, so the experimental results are difficult to reflect the actual condition...

Problems solved by technology

[0003] At present, the foundation of marine technology in China is weak and started late. Nutrient enrichment experiments are mainly carried out in shore-based laboratory simulations or in culture tanks on board. It is difficult to simulate the actual temperature, light and hydrodynamic conditions of seawater, so the experimental results are difficult to reflect the actual conditions of algae. In addition, the operation of marine ecological experiments requires a lot of manpower, often needs to add reagents overnight, and the automation ability is weak. Therefore, we propose an in-situ seawater nutrient enrichment experimental device and its method
