Abstract

The invention discloses a sea-weed seedling transplanting device which comprises a seedling protecting device and a base, wherein the seedling protecting device comprises a seedling protecting cover and a germinating slot; the seedling protecting cover comprises a frame and a protecting net sleeved on the frame; no protecting net is sleeved on the bottom surface of the frame of the seedling protecting cover; the lower end of the frame of the seedling protecting cover is detachably connected with the upper end of the germinating slot; an openable door is arranged on the protecting net on the upper end or side walls of the seedling protecting cover; an accommodating groove, which is matched with and is used for accommodating the germinating slot, is formed on the middle part of the base; connecting plates are fixedly connected with the outer side walls of the frame of the seedling protecting cover; fixing pipes are fixedly connected with the other ends of the connecting plates. The sea-weed seedling transplanting device is capable of avoiding the defects of damage to the sea-weed seedling rhizomes during a transplanting process and unstable combination with the bottom substrate of aplanting area. The protecting net on the seedling protecting cover is capable of preventing the sea-weed seedlings from being eaten by fishes during the growth process.

Description

Technical field:

[0001] The invention belongs to the field of ecological restoration of seagrass beds, and in particular relates to a transplanting device used in the ecological restoration process of seaweed transplantation after seaweed seeds germinate into seedlings. Background technique:

[0002] The seagrass bed ecosystem is an ecosystem with extremely high productivity in coastal waters, and the global average primary productivity of seagrass is 1012g DW m -2 d -1 , and higher than most other types of ecosystems in the biosphere. The seagrass bed ecosystem has important ecological service functions, such as raising young, reducing the risk of disease for humans and aquatic animals, purifying pollutants, and carbon sinks. However, since the 20th century, due to the impact of human activities and climate change, since 1940, the global seagrass bed has declined at an annual rate of nearly 7%. The degradation and disappearance of seagrass beds will lead to the weakening...
