Embodiment 1

[0019] A device for detecting the horizontal movement ability of phytoplankton. The device includes a cuboid tank and a light-shielding body. The light-shielding body is a cuboid lacking a top surface. One end is open, and the cuboid tank is made of transparent material, such as figure 1 As shown, the cuboid tank is composed of a cuboid tank body 1 and a spacer 2. The cross section of the cuboid tank body is a square, and the spacer is a square equal to the cross section of the cuboid tank body. A length surface of the cuboid tank body is missing , the inner wall of the cuboid tank body is evenly provided with two opposite grooves, the spacers are inserted into the grooves, and the number of the grooves is 11.

[0020] The cross-section of the cuboid groove is a square with a side length of 4 cm.

[0021] The interval between two adjacent grooves is 1 cm.

[0022] The length of described cuboid groove is 40cm.

[0023] After culturing the phytoplankton to the logarithmic ph...

Abstract

The invention provides a device and method for detecting the horizontal movement capacity of phytoplankton, and belongs to the ecological field. The device comprises a cuboid groove and a shading body; the shading body is a cuboid without a top surface; when in use, the shading body is just wrapped on the outer surface of the cuboid groove, and an open end is reserved; the cuboid groove is made ofa transparent material; the cuboid groove is composed of a cuboid groove body and a spacer, wherein the cross section of the cuboid groove body is a square, the spacers are squares equal to the crosssection of the cuboid groove body, one length surface of the cuboid groove body is missing, grooves which are opposite in pairs are uniformly formed in the inner wall of the cuboid groove body, the spacers are inserted into the grooves, and the number of the grooves is greater than 11. The invention also provides a method for detecting by using the device. According to the invention, the movementspeed of phytoplankton under light irradiation can be known for people, and the method is used for guiding the measurement of the vertical movement capability of phytoplankton.

Description

technical field [0001] The invention belongs to the field of ecology, and in particular relates to a device and a method for detecting the horizontal movement ability of phytoplankton. Background technique [0002] Affected by global climate change, seawater warming and ocean acidification are increasing. Ocean acidification and ocean warming have led to serious degradation of coral reefs, reduction of ecological functions, and decline in biological richness and production capacity, resulting in a decline in the overall aquaculture production potential of coastal countries. In turn, it will have a serious impact on the marine biological chain and the global ecosystem. These issues have also become research hotspots for governments, marine research institutions and scholars in recent years. The organic substances synthesized and stored by autotrophs during the growth and reproduction process are called primary productivity. In the ocean, surface autotrophs produce organic ma...
