Description

Technical Field

[0001] The invention relates to a method for cultivating kelp sprouts in sea areas, belonging to the technical field of seaweed cultivation. Background Art

[0002] Traditional kelp cultivation uses autumn seedlings grown indoors. After being released from the storage on the curtain sheets, the seedlings undergo over a month of offshore cultivation. Once they reach 5-15 cm in length, they are ready for seedling separation. Larger seedlings are selected for use in clamping and growing to meet the seedling supply for large-scale kelp cultivation. After separation and clamping, the remaining seedlings, along with the seedling ropes, are generally discarded. Research has found that immature kelp fronds (referred to as kelp buds of Saccharia japonica) measuring 30-50 cm in length contain twice the protein of mature fronds and exhibit numerous biological functions, including lowering blood lipids, regulating immunity, detoxifying lead, and providing antioxidant benefits. After harvesting, the fresh vegetables are blanched at 70°C, then processed or salted, resulting in a bright green color. Kelp buds processed to preserve their green color can be eaten directly or used as a substitute for hot pot vegetables. These crisp, tender, and refreshing kelp sprouts are highly popular with consumers. The green preservation process is simple, requires advanced equipment, and requires no additives, resulting in a significant output-to-cost ratio.

[0003] Construct appropriate cultivation facilities to cultivate the seedling ropes and winter seedlings after seedling separation to produce kelp sprouts. That is, if the density of the seedlings on the seedling ropes after seedling separation and clamping exceeds 3 plants / cm, kelp sprouts with a length of about 35 cm can be cultivated; by harvesting kelp sprouts in multiple batches and leaving smaller seedlings for further cultivation, multiple cultivations can be achieved; winter seedlings can also be used to produce kelp sprouts. Indoor seedling cultivation in winter requires less labor and energy than autumn seedlings, which allows for multiple seedling cultivations and makes full use of seedling cultivation facilities. The cultivation of kelp sprouts requires multiple harvests, so it is necessary to construct facilities that can float in seawater with smooth tides for a long time. At the same time, it is necessary to fix the seedling ropes to prevent them from sliding and causing friction and seedlings to fall off. Reducing the number of fixing points is more conducive to increasing yields. Summary of the Invention

[0004] The technical problem to be solved by the present invention is to address the deficiencies in the existing technology and provide a method for cultivating kelp sprouts in sea areas, which can float in seawater with smooth tides for a long period of time, solves the technical problem of seedlings falling off due to friction of seedling ropes, and is conducive to increasing production.

[0005] In order to achieve the above object, the present invention adopts the following technical solutions:

[0007] (1) Constructing a device for cultivating kelp sprouts in the sea area:

[0008] ① Setting the anchoring unit: Bundle multiple bamboos into a solid cylindrical shape to form a bamboo pile. The end of the bamboo pile is sharpened to a pointed tip and the top is smooth and flat. A round hole is set horizontally 0.5 meters away from the flat end. One pile is equipped with two pile cables. One end of each pile cable is tied to the pile after passing through the round hole, and the other end is reserved for tying the floating rope.

The fiberglass struts and the floating ropes are perpendicular to each other to form a multiple frame structure; the two ends of each floating rope are connected to the pile cables tied to the same side of different piles, so that the cultivation unit is set in the sea area and the fiberglass struts are kept parallel to the sea level;

[0010] ③ Set up the water layer adjustment unit: tie the float to the fiberglass support rod and pile cable through the hanging rope. Tie a float to each end of each fiberglass support rod, so that there are floats at the four corners of the frame structure in the cultivation unit; set a float on each pile cable; in the initial stage of cultivation, the length of the hanging rope is 50cm;

[0011] (2) Hanging seedling cultivation: In early November, the kelp seedling ropes shipped out of the warehouse are placed in the frame structure. A kelp seedling rope is tied to two floating ropes through multiple plastic ties to form multiple "Z" shapes. The kelp seedling ropes are naturally cultivated; the length of the hanging rope is 50 cm at the beginning of the cultivation.

[0012] (3) Harvesting: During harvesting, the boat enters from the side of the pile cable, moves slowly along the direction of the floating rope, slowly approaches the floating rope, pulls the two floating ropes together synchronously, and pulls out the long and large algae by hand, leaving the small seedlings and putting them back into the sea area for further cultivation; after 9-11 days, the small seedlings grow up and are harvested again. After 5-6 harvests, if it is found that the kelp seedling rope can no longer produce, the plastic tie is cut with scissors, and the newly-delivered kelp seedling rope is replaced and continued to be tied to the floating rope to achieve the renewal of seedlings and multiple cultivation.

[0013] In the above technical solution, in step (1), the device for cultivating kelp sprouts in the sea area includes an anchoring unit, a cultivation unit and a water layer adjustment unit, and is characterized in that:

[0014] The anchoring unit includes a pile and a pile cable: a circular hole is provided in the middle and upper part of the pile, and the pile cable passes through the circular hole and is tied to the pile; there are two piles, which are inserted into the seabed after being tied with the pile cables; there are four pile cables, and each pile is tied with two pile cables;

[0016] One end of the pile cable is passed through the circular hole and then tied to the pile, and the other end is connected to the end of the floating rope. The two ends of each floating rope are connected to the pile cables tied to the same side of different piles, so that the cultivation unit is placed in the sea area and the fiberglass support pole is kept parallel to the sea level.

[0017] The water layer regulating unit includes a float and a suspension rope, one end of the suspension rope is bound to the float and the other end is bound to the fiberglass reinforced plastic support rod / pile cable; a float is bound to each end of each fiberglass reinforced plastic support rod, so that a float is provided at each corner of a frame structure in the cultivation unit; a float is provided on each pile cable; the position of the cultivation unit in the water layer of the sea area can be adjusted by adjusting the length of the suspension rope.

[0018] In the above technical solution, the pile is a bamboo pile formed by bundling multiple bamboos, which is a solid cylindrical pile as a whole, with the end sharpened into a pointed end and the top end being a smooth flat end.

[0019] In the above technical solution, the pile has an overall height of 2 meters and a diameter of 25 cm, and is provided with a circular hole transversely through it at a position 0.5 meters away from the flat end, and the circular hole is used to pass through and bind the pile cable.

[0020] In the above technical solution, after the pile is passed through and the pile cable is tied, the entire pile body is inserted into the seabed and the pile cannot be exposed from the bottom to prevent rotting.

[0021] In the above technical solution, the pile cable is a polyvinyl chloride rope with a diameter of 2.4 cm and a length of 12-20 m.

[0022] In the above technical solution, the fiberglass support rod is hollow inside and sealed at both ends, with a length of 4m, an inner diameter of 8cm and a wall thickness of 0.6cm.

[0023] In the above technical solution, the fiberglass reinforced plastic struts are spaced 4 meters apart.

[0025] In the above technical solution, the plastic cable tie is of model TP-80M, with a length of 80 mm, a width of 2.5 mm, and a binding ring diameter of 16 mm.

[0026] In the above technical solution, when the plastic tie is used to bind the kelp seedling rope, the spacing between the plastic tie and the kelp seedling rope on the same floating rope is 25cm-27cm.

The fiberglass reinforced plastic support rod and floating rope are combined with the hardware and software of the site to form a square frame, in which the kelp seedling rope is tied. This unit is the main body of the kelp seedling cultivation device in the sea area, carrying the growth and harvesting operations. It is fixed in a space determined by the sea area by piles and pile cables. It is fixed in the water layer determined by the sea area by buoys and hanging ropes according to the growth law of kelp.

[0033] (2) Use plastic ties to tie the kelp seedling rope to the floating rope. The kelp seedling rope is relatively firm and cannot slide, which avoids the seedlings from falling off due to sliding. The plastic tie is easy to tie and cut, which is convenient for operations such as replacing the seedling rope at sea. The floating rope and the kelp seedling rope are fixed with plastic ties, and the "zigzag" layout is conducive to maintaining a certain distance and rapid harvesting.

[0034] (3) Plastic ties are easy to bind, which avoids the phenomenon of poor growth of kelp seedlings due to inappropriate light and seawater temperature, and also avoids seedling shedding caused by mutual friction; the device can adjust the water depth of the kelp seedlings according to the different cultivation periods, so that the kelp seedlings can gradually adapt to the sea environment such as light and water quality; the kelp buds grow better and have better quality, and can be cultivated in multiple crops to improve quality and efficiency.

[0035] (4) The water layer adjustment unit consists of a float and a suspension rope. The float is located above the fiberglass support rod and is connected by a suspension rope. Each 4*4 meter cultivation unit has 4 floats. The suspension rope is long in the early stage and shortened in the later stage. The position of the cultivation unit in the water layer can be adjusted, thereby adjusting the cultivation water layer. The water layer adjustment unit not only serves as a device for adjusting the water layer, but also as a marker of the water surface. The unit can adjust the cultivation water depth according to the different cultivation periods of kelp seedlings, so that the kelp seedlings can gradually adapt to the sea environment such as light and seawater temperature. Or in special circumstances, the suspension rope can even be extended to 2 meters to avoid possible hazards such as red tide or oil pollution. BRIEF DESCRIPTION OF THE DRAWINGS
