Problems solved by technology

With the protection and ecological restoration of the seagrass ecosystem in recent years, the important role of seagrass in the ocean has gradually been paid attention to. Ecologists and environmental scientists at home and abroad have carried out research on the physiological ecology of eelgrass, but at present The transplanting technology of eelgrass in the intertidal zone is relatively weak, and few studies have been carried out

Embodiment Construction

[0009] The method of the present invention will be described in detail below in conjunction with the examples.

[0010] In the northern sea area of ​​my country (taking the coast of Shandong as an example), the seeds of eelgrass generally mature in July, and seeds of eelgrass can be collected in good time at this time. The reproductive branches whose seeds have matured are selected for collection, and the reproductive branches are poured into a container after being collected, and filtered after being fully stirred, so as to obtain mature seeds. The reproductive branches can also be collected and hung in the natural sea area, and the seeds will fall off naturally. The overall maturity of the seeds obtained by this method is higher than that obtained by direct stirring and filtering.

[0011] Fully mix the collected eel algae seeds with stones, nitrogen fertilizer and glutinous rice flour, add water and stir. In the case of ensuring that the seeds, fertilizers, and glutinous r...

Abstract

The invention provides a sowing method of zostera marina seeds. The sowing method comprises the following steps: firstly, mixing the zostera marina seeds, stones and nitrogen fertilizers; then adhering the materials by glutinous rice flour; drying the mixture; and then sowing the mixture in a sea area. According to the method, the zostera marina seeds are placed in a slow-release system, so that certain weight is added to the zostera marina seeds which then can fall into a sowing area. In addition, components in the slow-release system can be provided for germination and growth of the zostera marina seeds, thus guaranteeing the survival rate of zostera marina.

Description

technical field [0001] The invention belongs to the field of cultivation of eelgrass, in particular to a method for sowing eel seeds. Background technique [0002] Zostera marina L., belonging to Angiospermae, Potamogetonaceae, Zostera L., is a perennial herb, mainly distributed in temperate seas in northern my country such as Shandong , Hebei and Liaoning and other coastal areas. The "seagrass field" formed by a large area of ​​eelgrass has extremely high marine ecological value and is an important symbol of a healthy marine environment. International research results show that the ecological service value of the seagrass ecosystem is significantly higher than that of the two major marine ecosystems of mangroves and coral reefs. Seagrass farms have extremely high productivity and can provide excellent habitats and spawning grounds for economic fish and many other marine organisms. They can also reduce the eutrophication level of the marine environment, maintain the nearsho...
