Description
Technical Field
The invention belongs to the technical field of kelp culture, and particularly relates to a kelp three-dimensional seedling raising device and a using method thereof.
Background
Kelp is the most important large economic seaweed in China, and the yield of kelp is the first of large economic seaweed in China for many years. It is a large-scale marine brown algae grown in low-temperature seawater. Kelp is a vegetable with high nutritive value, and is suitable for cooking methods such as mixing, burning, stewing and the like. Meanwhile, the compound has a certain medicinal value and contains rich mineral elements such as iodine. According to scientific determination: each 100 g kelp contains 8 g protein, 0.1 g fat, 0.57 mg carotene, 10.09 mg vitamin B, 20.36 mg vitamin B, 1.6 mg nicotinic acid, 50 mg iron, 216 mg phosphorus, 22 micrograms cobalt, a certain amount of vitamin C and the like. The kelp has low calorie, medium protein content and rich mineral substances. Researches show that kelp has various biological functions of reducing blood fat, reducing blood sugar, regulating immunity, resisting coagulation, resisting tumor, expelling lead, detoxicating, resisting oxidation and the like. The kelp is mainly preserved in the sun, the white powdery attachments on the surface of the dried kelp are iodine and mannitol, and the quality of the kelp without any white powder on the surface is poor. Next, the kelp was observed to be superior to those with broad-thick leaves, dark green or yellowish brown, and without dead yellow leaves. The edible kelp is selected to be free of sediment and impurities, clean, free of mildew and good in hand feeling.
China is the country with the highest cultivation scale and yield of kelp in the world. In the early stage, kelp seedlings are cultivated by a three-dimensional method, but the illumination is uneven, especially the light at the bottom is insufficient, so that the seedling raising effect is not ideal, and the kelp seedlings are developed to be completely replaced by a parallel cultivation method. The flat culture method is to spread a Zhang Yomiao curtain on the water surface for culture, so that uniform illumination can be ensured, and the specifications of the cultured seedlings are uniform. The seedlings raised by one seedling raising curtain can be used for 1 mu of cultivation area, and the kelp seedling raising room in China occupies huge land resources. However, by adopting the parallel culture method, the oxygen discharged by photosynthesis during seedling growth is covered by a seedling curtain and cannot be timely discharged into the air, so that a plurality of bubbles are generated to influence illumination and CO 2 The seedling curtain is required to be frequently lifted to stir the water body in the production so as to eliminate air bubbles and ensure the healthy growth of kelp seedlings. In addition, when the kelp seedling starts to grow at a high temperature in summer, the kelp seedling is taken out of the warehouse when the temperature of the seawater is reduced to 19-20 ℃. The water temperature needs to be controlled below 10 ℃ in the whole seedling raising period, so that the larger the seedling raising chamber is, the more energy is consumed.
