Owing to the accumulation of sediment in shallow seas caused by human activities, the coverage area of copper algae fields has been progressively diminishing, resulting in a continuous reduction of benthic habitats. To mitigate this issue, it is imperative to restore the degraded copper algae fields and establish suitable habitats. To address the issues of inadequate adhesion function and low survival rates of Sargassum horneri zygotes.. Based on the adhesive function of zygotes of macroalgae, in order to improve the efficiency of zygotes adhesion and transplantation, the hydrodynamic action impact experiments were carried out indoors and in intertidal zone. The adhesion ability of Sargassum horneri zygotes encapsulated by sodium alginate, sodium alginate with 3%CaCl₂ solution and Hyperhyperbolic Polymer Aradhesuve(HBPA) was studied. The result showed that: (1)Indoors zone: under the influence of hydrodynamic action(EI:3.9), sodium alginate adhesive could adhere for 5 days on average, and the average adhesion time increased for 2 days after spraying 3%CaCl₂ solution, and theattachment density of zygotes was 14ind./cm² and 24ind./cm² respectively. HBPA can adhere for more than 7 days in hydrodynamic action(EI:8.4). The highes attachment density of zygotes is 14ind./cm². (2)Intertidal zone: HBPA showed strong adhesion ability in three sites of intertidal zone S₁(EI:6.6), S₂(EI:5.0) and S₃(EI:4.0) to encapsulate zygote, and the attachment density of zygotes reached 1、14 and 21ind./100cm² respectively, which were higher than those groups of sodium alginate and the sodium alginate sprayed with3% CaCl₂ solution. Through indoor and outdoor hydrodynamic action experiments, it is found that the resistance of sodium alginate and sodium alginate additive fixed by spraying 3%CaCl₂ solution are weaker than that of HBPA, so it cannot be applied under the co-nditions of strong current and high wave energy, but it is the most convenient, pollution-free, low-cost and easy-to-obtain materials as artificial adhesives. HBPA has high viscosity, strong adhesion, low dissolution rate and go-od intertidal transplantation effect, and is expected to become a new underwater transplantation material. The rese-arch results will provide technical support for the ecological restoration and protection of largescale seaweed field.The findings of this study will facilitate the development and application of more efficient artificial adhesion agents and transplantation techniques, thereby promoting cost-effective and efficient methods for the ecological restoration of algal fields. This will aid in restoring the damaged algal ecosystems along the coast of Zhejiang and provide essential technical support for ecological restoration projects and marine carbon sequestration efforts in coastal islands and reefs throughout China.
