Seaweed transplanting device and seaweed transplanting method applied to coral debris bottom materials

Abstract

The invention discloses a seaweed transplanting device and seaweed transplanting method applied to coral debris bottom materials. The seaweed transplanting device comprises a plant growth tank and a plant wave-resistant hood capable of covering the plant growth tank, wherein the plant growth tank comprises ambient side frames and a lower bottom plate; lower bottom side supporting plates are respectively fixed to the lower part of a left side frame and the lower part of a right side frame, wherein the left side frame and the right side frame are opposite, a lower bottom plate inlet and outlet is formed in a position under a front side frame, the lower bottom plate is placed on the lower bottom side supporting plate, and the front end of the lower bottom plate penetrates out of the lower bottom plate inlet and outlet; the plant wave-resistant hood is a hood with an opening in the lower part, and comprises a frame body and a net covering the frame body; the shape of the opening in the lower part of the plant wave-resistant hood is adapted to the shape of the ambient side frames of the plant growth tank; a plurality of fixing ropes are also connected to the lower part of the plant wave-resistant hood; a door which can be opened and closed is arranged on the plant wave-resistant hood. The seaweed transplanting device applied to the coral debris bottom materials can be beneficial to fixation and combination of seaweed plants in the coral debris bottom materials, and the survival rate of transplanted seaweed is increased.

Description

Technical field: [0001] The invention belongs to the field of ecological restoration of seagrass beds, and in particular relates to a seaweed transplanting device and a seaweed transplanting method applied to coral debris substrates. Background technique: [0002] Seagrass beds are marine characteristic ecosystems with high coastal productivity. They play important ecological functions in fixing the substrate, protecting the coast, improving water quality and breeding biological larvae. They are called the three major coastal ecosystems together with coral reefs and mangroves. But in recent years, due to human activities and environmental degradation, global seagrass beds have been degraded at a rate of 7% per year around the world. Therefore, seagrass bed restoration is a hotspot in international marine ecological restoration, and seagrass transplantation is the main method of seagrass bed restoration. [0003] There are many methods of seagrass transplantation, which are ...

AI Technical Summary

Problems solved by technology

[0004] Tropical coral reef flats are ideal distribution areas for tropical seagrasses, and their substrates are loose, porous, low-hardness, low-strength, and brittle. In recent years, due to the degradation of coral reefs, a large amount of coral debris has accumulated; some Seagrass species are adapted to grow in sandy and coral debris environments; however, seagrass transplantation in this substrate environment is obviously not conducive to plant burial and external material fixation, and the combination of seagrass and substrate after transplantation is very poor

In addition, due to the light texture and large size of coral debris, it is easily affected by current disturbance in sea areas with strong wind and waves. The disturbance of the substrate will damage the roots and leaves of transplanted seagrass plants, and even uproot them, resulting in poor survival rates for seagrass transplants. Low
