Natural sea-area sowing method of zostera marina seed

Abstract

The invention relates to a natural sea-area sowing method of zostera marina seed, and the method comprises zostera marina seed sowing time, zostera marina seed pretreatment and zostera marina seed sowing. The zostera marina seed is sowed at later autumn. The zostera marina seed pretreatment steps comprise performing immersion disinfection on the zostera marina seed respectively by ethyl alcohol and HgCl2, flushing with aseptic seawater, putting in low-salt aseptic seawater, putting in a dark environment with proper temperature for pre-treating for a period. The zostera marina seed sowing steps comprise uniformly mixing pretreated zostera marina seed with bottom mud or silt, packing into a mesh bag, sealing with a cotton thread, flatly paving seabed, and mutually connecting and fixing the mesh bags by U-shaped iron wires, so as to form a flat-paved carpet type sowing unit. The method is capable of effectively improving the germination rate of the seed, also has extremely good promoting effect on growth of germinated seedlings and plants. By employing the mesh bag for sowing during sowing, complete reserving of the sowed zostera marina seed is guaranteed, and thus the utilization rate of the seed is improved.

Description

Technical field [0001] The invention relates to a method for sowing seaweed seeds in natural sea areas, in particular to a method for inserting eel algae seeds in natural sea areas. Background technique [0002] Seagrasses are aquatic monocots adapted to life in marine environments, with well-developed root systems and underground stems. Sea grassland is one of the three typical offshore ecosystems, which has important ecological functions and economic value. As the planet's most important primary producers, seagrass meadows provide food and diverse habitat, as well as spawning and shelter grounds, for numerous marine organisms. For coastal ecosystems, seagrass fields play a vital role in capturing sediments, stabilizing sediments, protecting dikes from wind, purifying water bodies, cycling nutrients, and sequestering carbon (accounting for about 15% of the annual carbon sequestration of the entire marine ecosystem). It is often used as a biological indicator species for w...
