Embodiment 1

[0032] In a bay, the method and device of the present invention were used to carry out the transplantation test of eel algae. Such as Figure 1-2 As shown, the eelgrass transplanting device is provided with a support and a eelweed fixing grid, and the eel algae fixing grid is placed in the bracket. The bracket is formed by connecting four upright columns 1 through four transverse beams 2, that is, two adjacent columns 1 of the bracket are connected together through beams 2. The height of the column 1 of the support is 21 centimeters, the length of the beam 2 is 40 centimeters, and the height of the column below the beam 2 is 17 centimeters. For the convenience of fixing the eelweed transplanting device in the sea area, the lower ends of the four columns 1 of the support are cut. The density of the material for making the support is greater than that of seawater, such as PVC pipe or stainless steel, which is made of a PVC pipe with an outer diameter of 2.5 centimeters in this...

Abstract

The invention relates to the field of ecological restoration and reconstruction of seagrass meadows, in particular to a method and device for transplanting zostera marina L.. The device is provided with brackets and zostera marina L. fixing grids, wherein the zostera marina L. fixing grids are put in the brackets; and one or a plurality of zostera marina L. fixing grids are put in each bracket. The method comprises the following steps: (1) fixing the zostera marina L. on the zostera marina L. fixing grids; (2) after the zostera marina L. plants are fixed on the zostera marina L. fixing grids, vertically clamping grooves at the two ends of a main plate on two spaced cross beams of the brackets; and (3) utilizing the device to transplant seagrass in the sea area. The method and the device have the following beneficial effects: the problem that the seagrass in the sea area in the subtidal zone is difficult to transplant is solved, and in combination with the simple, convenient and effective device, restoration and reconstruction of the zostera marina L. seagrass meadows in the subtidal zone can be conveniently and rapidly carried out; and meanwhile, the device can be recycled, thus saving the cost, and the used strings are made of degradable plant materials, thus not polluting the sea area.

Description

technical field [0001] The invention relates to the field of ecological restoration and reconstruction of seagrass fields, in particular to a method and device for transplanting eel algae. Background technique [0002] Seagrass meadows ecosystem, mangrove forest and coral reef ecosystem are considered to be three typical offshore marine ecosystems. And international research results show that the ecological service value of seagrass fields is significantly higher than that of mangroves and coral reefs. Seagrass is the only angiosperm that submerges in shallow water, and differentiates into organs such as roots, stems, leaves, flowers and seeds. Lush seagrass fields are like forests on land, an important symbol of a healthy marine environment, and are precious "undersea grasslands" or "undersea forests". Seagrass fields are high-productivity areas that can provide good habitats, nursery grounds and shelters for marine organisms such as fish, shrimps, crabs, and shellfish. T...
