Phytoplankton environmental condition simulation culture method and device

Abstract

The invention discloses a phytoplankton environmental condition simulation culture device and method. The device comprises a glass container, a supporting plate, a first synchronous wheel, a synchronous belt, a second synchronous wheel, a support, a stepping motor, a temperature probe, a salinity detector, a first upper water level probe water adding device, a second upper water level probe water adding device and a lower water level probe water pumping device. The culture method comprises the following steps: collecting environmental conditions for growth of the phytoplankton, wherein the environmental conditions comprise illumination, temperature, salinity and the like; using multi-condition control intelligent software to separate or synthesize illumination-temperature-salinity conditions, obtaining the change frequency and range of environmental conditions, and culturing the phytoplankton. According to the method, the adaptability of the phytoplankton to illumination, temperature and salinity and the optimal growth condition can be analyzed and determined through one experiment, so that the optimal environment condition of the phytoplankton is screened out, so that relevant physiological experiments of the phytoplankton and rapid development of a red tide outbreak mechanism are facilitated, and a large amount of manpower and material resources are saved.

Description

technical field [0001] The invention relates to the field of marine science and technology, in particular to a method and device for simulating environmental conditions of phytoplankton. Background technique [0002] The growth of phytoplankton is affected by many biotic and abiotic environmental factors, including predators, light, temperature, salinity, nutrients and water velocity, among which light, temperature and salinity are three key influencing factors. According to the growth and distribution characteristics of phytoplankton, the frequency and range of changes in the three environmental conditions of light, temperature and salinity can be intelligently regulated to simulate real environmental conditions, and to study the growth of phytoplankton under real environmental conditions. [0003] Phytoplankton, also known as microalgae, have chromophores like land plants and need sunlight to grow and reproduce. Most of the phytoplankton float in the upper part of the sea...

Problems solved by technology

[0005] The technical problem to be solved by the embodiments of the present invention is that in the current experimental method for studying the growth of phytoplankton by environmental conditions, the environmental conditions of light, temperature and salinity are mostly set separately and cannot be automatically intelligently controlled and monitored over time. Can not simulate the complex real environmental conditions of continuous change, can not be applied to and respond to the problem of compound mechanism research on the growth and proliferation of offshore phytoplankton and the outbreak of red tide, a method for simulating the cultivation of phytoplankton environmental conditions is proposed
