Artificial algal reef for algae adhesion and seaweed transplantation

Abstract

The invention relates to an artificial algal reef for algae adhesion and seaweed transplantation. A reef body is a three-dimensional structure made of pervious concrete with a porosity of 15%-25%, six sides of the reef body are hollow, flow blocking plates are arranged on four sides of the reef body, a gentle water flow environment is created by an area encircled by the four flow blocking plates and is used for seaweed plant transplantation, the flow blocking plates and the reef body are integrally poured, bundling holes are arranged on two sides of the flow blocking plates and can be used for bundling scallop shell cages or oyster shell cages, algae adhesion effect is further improved, functions of the algal reef are expanded, and fixing strips are arranged at the bottoms of four corners of the reef body and are integrally poured with the reef body so as to guarantee stability after the reef body is placed into the sea. The artificial algal reef is low in cost, stable in structure and good in water permeability, the surface is rough to be favorable for algae adhesion, the gentle water flow environment created by the flow blocking plates is favorable for survival of transplanted seaweed plants, and after placed into the sea, the reef body is high in stability, multi-functional and expandable.

Description

technical field [0001] The invention relates to an artificial algae reef, in particular to an artificial algae reef which takes both algae attachment and seaweed transplantation into consideration. Background technique [0002] Seagrasses are aquatic monocots adapted to life in marine environments, with well-developed root systems and underground stems. Sea grassland is one of the three typical offshore ecosystems, which has important ecological functions and economic value. As the planet's most important primary producers, seagrass meadows provide food and diverse habitat, as well as spawning and shelter grounds, for numerous marine organisms. For coastal ecosystems, seagrass fields play a vital role in capturing sediments, stabilizing sediments, protecting dikes from wind, purifying water bodies, cycling nutrients, and sequestering carbon (accounting for about 15% of the annual carbon sequestration of the entire marine ecosystem). It is often used as a biological indicat...

Problems solved by technology

[0005] In order to overcome the shortcomings of the existing seaweed plant transplantation technology, such as the low survival rate of transplanted seaweed plants and the high cost of existing artificial algae reefs, poor algae attachment effect and single function, the present invention provides an artificial algae that takes into account both algae attachment and seaweed transplantation. Reef, the artificial algae reef is not only low in cost, but also conducive to algae attachment, and can also create a gentle water flow environment, thereby improving the survival rate of transplanted seagrass plants
