Problems solved by technology

[0003] Duckweed mostly lives on the surface of still fresh water, and a few live in waters where the current velocity is less than 1m / s. Photosynthesis, if the duckweed is knocked over, it will die because it cannot carry out photosynthesis, and if the pile is too thick, it will lead to insufficient light, which will lead to the death of duckweed, so duckweed is mostly afraid of waves
At present, there is no report about the normal growth of duckweed in wavy water bodies with a water velocity greater than 1m / s, which seriously restricts the development and application of duckweed energy utilization. Duckweed cultivation wave dissipation device

Abstract

The invention belongs to the technical field of energy plant cultivation and provides a duckweed-culturing wave-eliminating device. One structure adopted by the duckweed-culturing wave-eliminating device is a frame body I, wherein the frame body I is formed by at least three louver blade assemblies in a surrounding manner; the top surface and the bottom surface of the frame body I are open; the side surfaces of the frame body I adopt a louver blade structure. Another structure adopted by the duckweed-culturing wave-eliminating device is composed of a frame body II and coamings, wherein the frame body II is formed by louver blade assemblies in a surrounding manner; the coamings are arranged at the periphery of the frame body II. The third structure adopted by the duckweed-culturing wave-eliminating device is formed by at least three perforated frame bodies III with different sizes, which are nested and combined together; the top surface of each perforated frame body III is open; during nesting and combining, the opening of each perforated frame body III faces up. When the duckweed-culturing wave-eliminating device is used for duckweed cultivation, impacts, of waves of a flowing water body, on duckweeds, can be weakened or eliminated, the area of a water surface suitable for growth of the duckweeds can be increased, and the yield of the duckweeds can be increased.

Description

technical field [0001] The invention belongs to the technical field of energy plant cultivation, and relates to a duckweed cultivation wave-elimination device and its application in duckweed cultivation. Background technique [0002] Duckweed is the general name of Lemnaceae plants. There are 5 genera and 38 species in total. They are distributed all over the world. CO 2 , Absorb nitrogen, phosphorus and other substances from water, and can directly use wastewater to grow without pretreatment such as sterilization. Duckweed can convert nitrogen, phosphorus and other substances absorbed from water into starch, protein, cellulose, etc., and the starch content can be as high as 75% of the dry weight of duckweed. It has a very high potential for comprehensive utilization and can realize domestic sewage. Resource utilization will not become a secondary pollution source. Duckweed also has outstanding advantages over other aquatic plants: (1) fast reproduction speed, one generat...
