Seeding method of seaweed seeds

Abstract

The invention discloses a seeding method of seaweed seeds, which comprises the following steps of: selecting the locally produced proper seaweed seeds and proper superficial benthic bivalve organisms of a planting sea area; preparing glutinous rice flour slurry; smearing the glutinous rice flour slurry on the shell surfaces of the proper superficial benthic bivalve organisms which are wiped cleanly; sticking the seaweed seeds to the glutinous rice flour slurry on the superficial benthic bivalve organisms; and broadcasting the superficial benthic bivalve organisms stuck with the seaweed seeds at an appointed sea area. As an improvement, seaweed seed embryos relatively to one side are stuck to the glutinous rice flour slurry, and the seeding density of the seaweed seeds is more than 200 grains per square meter. The seeding method is simple and effective and has low cost, and the whole preparation and seeding work is carried out on water, thereby saving human and material resources required by underwater operation. In addition, the seeding method can avoid the damage to seabed benthonic organisms, an adhesive is nontoxic and harmless and is rapidly degraded, locally fished local species are selected as carrier organisms, and a problem of biologic security does not exist.

Description

Technical field [0001] The invention relates to a seaweed seed sowing method, in particular to a seaweed seed sowing method that can be used for seaweed field restoration. Background technique [0002] Due to the many advantages of seagrass seeds in the ecological restoration of seagrass fields, in recent years, many scientific research institutions have devoted themselves to the use of seagrass seeds (mainly phylloxera seeds) for seagrass field restoration. However, after the seagrass seeds are sown in the sea area, the seagrass seeds cannot be quickly and effectively fixed on the bottom of the seabed, causing a large amount of loss or being swallowed by other organisms. The rapid planting of seaweed seeds into the bottom of the sea not only reduces the waste of seeds, but also effectively improves the survival rate and germination rate of seaweed seeds. American researcher Robert J. Orth published an article in Aquatic Botany 90 (2009) 204-208, "Evaluation of a Mechanical Plan...

Problems solved by technology

U.S. Patent No. 6,718,890 (April 13, 2004) discloses an underwater seagrass seeding apparatus (Underwater seagrass seeding apparatus), which fixes the seagrass seed injection device on an underwater towed platform, and the underwater towed platform is towed on the surface of the seabed. During the process, the seaweed seed injection device injects the gel-solidified seeds into the seabed substrate. Although the device greatly improves the seeding efficiency of seaweed seeds, the underwater seaweed seeding device is expensive and the cost of use is high, and the underwater seaweed seeding device It can only work on the sediment bottom. In addition, the use of this device will easily damage the benthic organisms.

Therefore, the application of this underwater seagrass seeding device is limited
