A device for cultivating seaweed with seabed ooze

Abstract

The invention provides a device for cultivating alga with globigerina. According to the technical scheme, a plurality of boxes (5) are connected with welding box rings (3) on sides of the boxes through a rope above the flood tide (4) or along the sea current direction (2) to form a row, the box rings (3) at the two ends of a group of the boxes (5) are each connected with an iron anchor (1), and the two iron anchors (1) are thrown so as to straighten the connecting rope and fixe the group of the boxes (5); the cultivation boxes (5) are floated on the sea surface and parallel to lifting ropes (8) for cultivating the alga, the cultivation boxes (5) are before the sea current direction (2), and the lifting ropes (8) for cultivating the alga are behind the sea current direction (2); an alga cultivating device is mainly composed of floating ropes (6), floats (7), the lifting ropes (8), weight stones (9), seedling ropes (10) and wood piles (11). The device has the advantages that the globigerina is circularly utilized, healthy, efficient and large-scale economic alga cultivation is achieved, and the high-yield, efficient and environment-friendly requirements of modern fishery development are met.

Description

technical field [0001] The invention relates to the technical field of seabed ooze cultivation, in particular to a device for cultivating seaweed with seabed ooze. Background technique [0002] Large economical seaweeds in seaweed farming mainly refer to kelp, seaweed, wakame, hijiki, asparagus, etc. Their growth in seawater is done by absorbing nutrients in water through photosynthesis. When the nutrient content in seawater is too low Or without it will affect their normal growth, so the nutrient salt is the key to the success or failure of seaweed cultivation. Under natural conditions, fresh water entering the sea brings a large amount of nutrients and organic matter to large-scale economic seaweed breeding waters. The organic matter is decomposed and oxidized by microorganisms to produce nutrients, which are used for the growth of large-scale economic seaweed. However, when the rainfall is insufficient, the amount of fresh water entering the sea will decrease. If the nut...

AI Technical Summary

Problems solved by technology

Under natural conditions, fresh water entering the sea brings a large amount of nutrients and organic matter to large-scale economic seaweed cultivation waters. If the nutrient content in the cultured waters is low, the growth of large economical algae will be affected, and the situation of relying on the weather has not been eliminated. Similarly, when the large economical algae grows, the nutrient salt will be consumed, and the nutrient content in seawater will decrease. Continuous supply of nutrients will also affect the growth of large economical seaweeds. In seaweed cultivation, measures such as hanging bag fertilization, pouring fertilizers, and soaking fertilizers are generally used to supplement seawater nutrients. Environmental pollution, which leads to a decline in the production and quality of large-scale economic algae cultured, causing economic losses to farmers
