Problems solved by technology

[0003] However, phytoplankton often gather in groups and float on the surface of natural water bodies, and the differences among different individuals are very large. The previous phytoplankton counting method usually uses the microscopic counting method, that is, to use a microscope to count the cells of the phytoplankton concentrated sample, but the whole The counting process is relatively complicated, requiring staff to count multiple fields of view, the reproducibility is poor, and it is not suitable for the determination of multiple samples. Counting efficiency and precision

Abstract

The invention discloses a phytoplankton counting method and device, and the method comprises the steps: obtaining an original phytoplankton liquid sample; processing the original phytoplankton liquid sample to obtain a slide sample which can be used for microscopic image processing; acquiring a microscopic image of the slide sample, and processing the microscopic image to obtain a phytoplankton counting result. The method can be used for rapid monitoring of actual algae, facilitates timely providing of water body phytoplankton information, and can provide technical support for prediction and early warning work of phytoplankton algal blooms.

Description

technical field [0001] The invention relates to the technical field of algae monitoring, in particular to a method and device for counting phytoplankton. Background technique [0002] At present, phytoplankton are mainly distributed in many places such as rivers, lakes and seas. They are indicator organisms for measuring water quality. The water quality of a water area is closely related to the richness of phytoplankton and the composition of the community. The reduction or excessive reproduction of phytoplankton, would foretell that those waters are heading for the worse. For example, the increase in the number of phytoplankton in lakes, especially the rampant growth of cyanobacteria and the extension of the growing season is an important sign of eutrophication in lakes. Therefore, monitoring the number of phytoplankton cells can provide first-hand information for early warning and control of water quality monitoring. [0003] However, phytoplankton often gather in groups ...
