Device and method applied to tropical island seaweed transplanting

Abstract

The invention discloses a device and a method applied to tropical island seaweed transplanting. The device comprises a basket frame and ground nails for fixing the basket frame, wherein the basket frame comprises an upper top frame, a lower bottom frame and connecting rods connecting the upper top frame and the lower bottom frame; an upper grid is arranged in the upper top frame; the aperture of the upper grid allows a seaweed plant to pass freely; the lower bottom frame is provided with a lower grid; the bottom part of the basket frame is movably connected with the ground nails; and the distance between the upper grid and the lower grid is matched with the height of the seaweed undersea part. According to the device and the method applied to tropical island seaweed transplanting, the efficiency of processes such as seaweed plant collection, temporary cultivation, transplanting unit production, transportation and transplanting implementation can be improved significantly, fixation andcombination of seaweed plants on coral debris or coral sand substrate of tropical island reefs can be realized, tropical island storm can be effectively resisted, and the survival rate of seaweed transplantation is improved.

Description

Technical field: [0001] The invention belongs to the technical field of ecological engineering, and in particular relates to a device and method for transplanting seaweed in the intertidal zone, which are applied in ecological restoration projects of tropical islands and reefs. Background technique: [0002] The seagrass bed ecosystem is an important ecosystem along the coast of islands and reefs. It has important ecological functions of protecting islands and reefs. It is extremely important for reducing damage from storms and typhoons, mitigating ocean currents and wave erosion, replenishing lost sand and rocks, and stabilizing the structure of islands and reefs. It also provides habitats, protected areas, breeding and feeding places for many important organisms including endangered species, and can provide resources such as fisheries and medicinal organisms, as well as rich and diverse underwater landscapes. However, the seagrass ecosystem is one of the most fragile ecosy...

AI Technical Summary

Problems solved by technology

First of all, the coral debris and coral sand substrate are loose, coupled with high wind and high waves, try the existing plant fixation method to transplant seagrass on tropical islands and reefs, common storm surges will stir up the transplanted seagrass from the sediment Therefore, the fixation of the transplanted unit has become one of the key technical issues to be solved urgently; secondly, for seagrass transplantation on tropical islands and reefs, it is necessary to collect seaweed seedlings and carry out long-distance transportation. During the long-distance transport of seagrass, seagrass plants are mostly transported by single plant, and the existing plant transplantation methods are mostly single plant transplantation, resulting in low efficiency of seagrass transplantation and difficulty in forming a large scale. It is not easy to obtain seedlings in the supply area of ​​species, and efficiency is very important in seagrass transplantation on tropical islands and reefs. From seagrass plant collection, temporary cultivation, transplantation unit production, transportation and transplantation implementation, an efficient method is urgently needed. Therefore, How to improve the efficiency of seagrass transplantation is the second key technical problem to be solved urgently
