Zostera marina young seedling manual culture method

Abstract

The invention relates to a zostera marina young seedling manual culture method, which comprises the steps of water temperature setting, salinity setting, illumination setting, substrate setting, dissolved oxygen content setting and water circulation setting during zostera marina young seedling manual culture. During the water temperature setting, the water temperature is controlled to be two gradients, and the water temperature in a young seeding culture initial stage is lower than that in a second stage; during the salinity setting, the water body salinity is controlled to be a in low-salinity environment; during the illumination setting, the illumination time cannot be too short every day, and the photo flux density is proper; during the substrate setting, the pavement thickness is proper, and the substrate is fine sand with the prior particle diameter; during the dissolved oxygen setting, a water body is continuously oxygenated for preventing the too low dissolved oxygen content; during the water circulation setting, the water body continuously circulates, and the circulation speed is prevented from being too higher. The method obtained in the way has the advantages that the large-scale manual culture of zostera marina young seedlings can be realized, and the growth effect of the zostera marina young seedlings can also be obviously improved.

Description

technical field [0001] The invention relates to a method for artificially cultivating seaweed seedlings, in particular to a method for artificially cultivating eelgrass seedlings. Background technique [0002] Seagrasses are aquatic monocots adapted to life in marine environments, with well-developed root systems and underground stems. The seagrass field constructed by it is one of the three typical offshore ecosystems and 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 indic...
