Description

Technical Field

[0001] The invention relates to the technical field of seaweed seedling marine culture, in particular to a bionic culture device for cultivating seaweed seedlings. Background Art

[0002] Graminaria is an important agar-producing economic red algae, mainly cultivated in coastal provinces such as Fujian, Guangdong, and Shandong, and its output ranks second in my country. Graminaria is rich in protein, dietary fiber, multiple minerals, essential amino acids and trace elements for the human body, and is a typical high-protein, low-fat seaweed. Its polysaccharide components have physiological activities such as antioxidant and anti-tumor activities, and have the potential to develop health food and green food.

[0003] With the continuous expansion of the agaricus industry, the problems that arise in the agaricus breeding process are becoming increasingly serious, restricting the development of the agaricus industry. The main problem is the degradation of germplasm. Affected by the marine environment, the agaricus has a reduced resistance to stress after multiple generations of breeding, and cannot maintain the excellent traits of the parent. Once the environment is not suitable, it is easy to cause disease and rot; in addition, the agaricus seedlings are relatively single and cannot meet the growing needs of the global agar industry. The problem of the source of improved varieties required for large-scale promotion directly restricts the development of the agaricus breeding industry. Since the indoor growth rate of the agaricus algae tip is slow, the relative growth rate of the algae is about 6% / d. At the same time, the indoor breeding conditions do not meet the actual marine breeding conditions of the agaricus, so the small-scale marine breeding method is adopted to complete the subsequent breeding of new varieties of agaricus. However, the breeding of agaricus seedlings in the sea area faces new problems, such as the algae tip is too small, and it is impossible to adopt the method of algae segment clamping seedlings for cultivation and breeding; excessive light intensity has an inhibitory effect on the growth of the algae tip; the attachment of miscellaneous algae has an adverse effect on the growth of agaricus, etc. The above problems have seriously affected the progress of subsequent new variety breeding, and therefore a device and technology for small-scale marine culture and new variety breeding of Gracilaria lemaneiformis is urgently needed. Summary of the invention

[0004] In view of the above situation, in order to overcome the defects of the prior art, the present invention provides a bionic culture device for cultivating Gracilaria seedlings, which effectively solves the problems that when cultivating Gracilaria in sea areas, the algae tips of the seedlings are too small to be cultivated and selected by the method of clamping the seedlings with algae segments, the excessive light intensity has an inhibitory effect on the growth of the algae tips, and the attachment of miscellaneous algae has an adverse effect on the growth of Gracilaria, which seriously affects the progress of subsequent new variety selection.

[0005] To achieve the above object, the present invention provides the following technical solution: comprising a breeding rack, the breeding rack is composed of a horizontal tube and a vertical tube, a metal plate is arranged at the bottom of the breeding rack, four top ends above the breeding rack are welded with metal hooks, the metal hooks are connected to a ring through a first connecting rope, a plastic cylindrical float is arranged at the upper end of the ring, the lower end of the ring is connected to a metal anchor through a second connecting rope, and a fishing net is connected to the periphery of the plastic cylindrical float;

[0006] A breeding area and an expanded culture area are arranged inside the breeding rack. The breeding area is located in the center of the expanded culture area. The breeding area and the expanded culture area are connected by a first metal wire. The breeding area is divided into a number of breeding grids by a second metal wire and a third metal wire. A first black gauze is arranged above the breeding area, a first white gauze is arranged around the breeding grids, a second black gauze is arranged above the breeding grids, a second white gauze is arranged around the expanded culture area, and a third white gauze is arranged above the expanded culture area.

[0007] Preferably, the expansion culture area is composed of four trapezoidal bodies of equal volume, and a fourth white gauze with a length of 2 m, a width of 20 cm and a pore size of 0.5 mm is respectively arranged around the inside of the four trapezoidal bodies.

[0008] Preferably, the first connecting rope is a polyethylene fiber rope with 3000 filaments, and the second connecting rope is a polyethylene fiber rope with 5000 filaments.

[0009] Preferably, the fishing net has an aperture of 3 cm and a width of 1 m.

[0010] Preferably, the first metal wire is a stainless steel wire with a length of 0.7 m and a thickness of 2 mm, the second metal wire is a stainless steel wire with a length of 1 m and a thickness of 2 mm, the third metal wire is a stainless steel wire with a length of 20 cm and a thickness of 2 mm, and the breeding grid has a length of 8 cm, a width of 8 cm, and a height of 20 cm.

[0011] Preferably, the first black gauze has a length of 1m, a width of 1m, and a pore size of 0.5mm, the first white gauze has a length of 20cm, a width of 8cm, and a pore size of 0.3mm, and the second black gauze has a length of 8cm, a width of 8cm, and a pore size of 0.3mm.

[0012] Preferably, the horizontal tube, vertical tube, metal plate, metal hook and ring are all components made of stainless steel.

[0013] Preferably, the metal plate has a length of 2 m, a width of 2 m, and a thickness of 0.5 m, and a certain amount of sand and small stones are fixed above the metal plate.

[0014] The invention first adds an artificial matrix on the metal plate to promote the growth of the agaricus seedlings, imitates the growth conditions of the agaricus seedlings in the natural environment to make them grow better, and then divides the regional cultivation into breeding areas and expanded cultivation areas, and the breeding and expanded cultivation do not interfere with each other, and each algae is relatively independent and does not affect each other, thereby ensuring the accuracy of the rapid growth rate of a single algae strain and the maximum utilization of resources. The invention has the advantages of easy operation, a large number of cultured juveniles, and a large number of individuals bred at one time. Furthermore, the white gauze of different specifications is used in combination to filter seawater in multiple layers, ensuring that the seawater can be exchanged while also ensuring that there is no biological pollution in the culture rack, protecting the growth environment of the agaricus and making it grow rapidly. The layered filtering structure can effectively reduce the influence of marine floating objects and miscellaneous algae on the cultivation of the agaricus in the sea area, fully utilizing the fluidity of natural seawater, increasing the oxygen content, and promoting the rapid growth of the algae. The common use of nets can effectively seal algae and reduce economic losses caused by algae escape. In addition, sharing two kinds of gauze can also play a multiple protective role for Gracilaria and prevent algae death due to excessive light. Finally, the aquaculture water layer can be adjusted according to the real-time light intensity to adjust the light received by Gracilaria. When the light is weak, the algae growth can be promoted by adjusting the water layer. According to the triangle theorem, the aquaculture water layer can be adjusted by adjusting the rope length of the first connecting rope to meet the light requirements of Gracilaria at different stages. When the light is strong, the first black gauze and the second black gauze are used to protect the young algae tips to avoid the death of algae caused by direct sunlight in the sea area. Artificial adjustment of the aquaculture water layer of Gracilaria can be used in conjunction with the light protection control system for double adjustment to ensure the normal and rapid growth of the algae, thereby quickly screening out the algae that really grows fast in the natural sea area, and increasing the efficiency of new variety breeding.
