Embodiment 1

[0020] In the sea area where the eelweed is distributed along the coast of Shandong, such as the coasts of Qingdao and Weihai, the mature seeds were collected on June 21, 2008. The mature seeds are brown, and the fruit is hard, which is difficult to crush with fingers. On July 15, From then until the beginning of August, in addition to collecting mature seeds, also collect those that look immature. The immature seeds are light green and have a certain degree of hardness, but they can be crushed with fingers, that is, the whole eelgrass with seeds is collected. reproductive strain.

[0021] Indoors collect both ripe seeds and those that look immature and keep them separately. All seeds are refrigerated and stored in natural seawater at a temperature of 0-5°C. Just change the seawater at 0-5°C once a day, and pick out individual rotten seeds in time for later use. About 1000 mature seeds and 2000 immature seeds were tested.

[0022] On August 20, 2008, the water temperature o...

Abstract

The invention relates to a recovery technology for sea ecology, in particular to a method for budding eelgrass seeds, cultivating seedlings and recovering a sea grass bed. Eelgrass seeds are collected and the collected seeds are manually preserved; the temperature of the eelgrass seeds is controlled for cultivating the eelgrass seeds; the eelgrass seeds are activated to bud; and after the seeds bud, eelgrass seedlings can be planted or cultivated to a natural sea area suitable for the growth of eelgrass in respective four cultivating stages so as to form the sea grass bed and realize the recovery of the sea grass bed of the eelgrass. In the invention, the problem that most of the eelgrass seeds cannot be converted into an eelgrass adult plant under a natural sea area condition is solved; the cultivated eelgrass seedlings can be planted or cultivated into the natural sea area in respective four stages; and the budding success rate of the eelgrass seeds and the adult success rate in thenatural sea area are obviously increased.

Description

technical field [0001] The invention relates to marine ecological recovery technology, in particular to a method for eel algae seed germination, seedling cultivation and seagrass field recovery. Background technique [0002] Seagrass meadows ecosystem, mangrove forest and coral reef ecosystem are considered to be three typical offshore marine ecosystems. And international research results show that the ecological service value of seagrass fields is significantly higher than that of mangroves and coral reefs. Seagrass is the only angiosperm that submerges in shallow water, and differentiates into organs such as roots, stems, leaves, flowers and seeds. Lush seagrass fields are like forests on land, an important symbol of a healthy marine environment, and are precious "undersea grasslands" or "undersea forests". Seagrass fields are high-productivity areas that can provide good habitats, nursery grounds and shelters for marine organisms such as fish, shrimp, crab, and shellfis...
