Embodiment Construction

[0032] The technical solution of the present invention will be further described in detail below in conjunction with specific embodiments.

[0033] The method for artificial propagation of wild kelp of the present invention specifically adopts the following steps:

[0034] (1) Choose a suitable wild kelp breeding site:

[0035] It is generally chosen to arrange seabed fixed piles on the seabed in advance on the edge of the damaged kelp population, or on the reef seabed with smooth water circulation and suitable light. The seabed fixed piles are arranged in a dot matrix on the seabed, and the upper part of the pile body is provided with buttonholes, which can be used for seabed fixing of transplanted nets.

[0036] (2) Prepare to grow kelp:

[0037] Wild kelp seedlings are generally harvested in mid-to-late October when wild kelp with more leaf sporangia is selected as the seed kelp. Before using the seed kelp, the floating mud and weeds should be removed. The dry treatment is 2-3h, and...

Abstract

The invention provides an artificial reproduction method for wild kelps. The artificial reproduction method particularly includes the steps: (1) selecting a proper wild kelp reproduction site; (2) preparing parent kelps; (3) preparing spore fluid; (4) preparing a seedling collection box and a transplantation network; (5) collecting seedlings; (6) temporarily rearing the seedlings in a workshop; (7) temporarily rearing the seedlings on the sea; (8) separating the seedlings; (9) cultivating artificial seedlings; (10) transplanting the seedlings on a seabed. The seedlings are collected and intermediately cultured by the aid of the seedling collection box and the transplantation network in special design, rapid reproduction of artificial reproduction seedlings is realized, the influence of variable seabed terrains is overcome, and large-area seabed reproduction is realized.

Description

Technical field [0001] The invention belongs to the field of marine ecological protection and restoration, and particularly relates to a method for artificial propagation of wild kelp. Background technique [0002] Kelp is a kind of brown algae species with economic value. After long-term artificial cultivation, there are obvious differences in traits between artificially cultivated kelp species and wild kelp species. Although the area of ​​cultivated kelp is increasing, the natural distribution area of ​​wild kelp is showing Decreasing trend. Wild kelp is usually fixed on the reef 2-5 meters deep below the offshore tide line, and often forms a large area of ​​seaweed bed, which can provide habitat, foraging and spawning places for benthic and swimming creatures on the seabed, so it has an important ecological significance. However, in recent years, with the destruction of the offshore environment (such as artificial cofferdams, port projects, etc.), the original wild kelp popu...
