Experimental facility and experimental method for researching influences of water flow to attachment, germination and growth of alga spores

Abstract

The invention discloses an experimental facility and an experimental method for researching influences of water flow to attachment, germination and growth of alga spores. The experimental facility comprises a flowing water circulating system, wherein the flowing water circulating system is provided with a flowing water environment simulating water tank, a flow collecting part, a circulating water tank, a water pump, a water pipe and a water tap; the water pump can be used for pumping liquid in the circulating water tank; a water outlet of the water pump is communicated with a water inlet of the water tap by the water pipe; the water tap is arranged over a water storage tank of the flowing water environment simulating water tank so that water flow which flows out of the water tap can sequentially pass through the water storage tank of the flowing water environment simulating water tank, a first water discharging gap, a flowing water tank, a second water discharging gap, the flow collecting part, the circulating water tank, the water pump and the water pipe to form circulation. The experimental facility disclosed by the invention can be used for controlling the speed of water flow in the flowing water tank so that the water flow in the flowing water tank is quite stable and easy to control, and has the advantages of being low in cost, small in floor space, simple and convenient in application method and capable of easily controlling the temperature and light illumination to be the same.

Description

technical field [0001] The invention relates to an experimental device for studying the effect of water flow on the attachment, germination and growth of seaweed spores, and an experimental method using the experimental device to study the effect of water flow on the attachment, germination and growth of seaweed spores. Background technique [0002] Water flow, like temperature and light, is also one of the factors that affect the growth and development of seaweed. Finding out the appropriate water flow velocity for the growth and development of the studied seaweed will help to optimize the cultivation conditions of industrial seedlings and the selection of breeding areas. At present, there are many studies on temperature and light on the attachment, germination and growth of seaweed spores under laboratory conditions, but few studies on the attachment, germination and growth of seaweed spores by water flow, which are related to the poor control of water flow speed and the la...

Problems solved by technology

At present, under laboratory conditions, there are many studies on the attachment, germination and growth of seaweed spores by temperature and light, but few studies on the attachment, germination and growth of seaweed spores by water flow, which are related to the poor control of water flow speed and the lack of simple experimental methods.
