Kelp harvested directly after relying on the sun drying is called light dry, light dry kelp is widely used, no loss of nutrients, is the extraction of iodine, glue, alcohol raw materials. Frequent consumption of the sea with the role of prevention and treatment of goiter disease. In addition, a large number of products are also exported every year. The kelp processing standards have been stipulated (revised and issued on April 1, 1979). In addition to strict implementation in accordance with national regulations, some problems that often occur must be given high priority.
(1) As seaweed chemical kelp, should be dried carefully to ensure that the moisture content does not exceed the specified 22%; careful removal of impurities to ensure that does not exceed the provisions of 2%, as a chemical raw material must not be doped to leave the country and The use of the unit is responsible.
(2) As an export product, it is necessary to strive for a sun-drying on the same day; it must not contain impurities, sporangia, stems, yellow and white edges, etc.; the color must be thick brown, and it should not be shoddy and damage the national honor.
1 Substratum: The bottom of the sea is preferably flat and undulating, or has a certain degree of inclination. The second is the boulders. In addition, gravel or gravel sediments can also be proliferated by throwing stones.
2 Water quality: The water quality is clean, and the natural nitrogen content can always be maintained at about 10 milligrams per cubic meter. There are many suspended solids in the sea water, sediments and floating sludge on the rocky reefs cannot be used.
3 Depth: Generally, it can be down to 2.5 meters from the low tide line.
4 Biology: There is a large amount of algae growing on the surface of the reef and should not be used. Although it can be eliminated, it is too costly to work out.
5 Flow rate: According to investigations, the flow rate does not exceed 60 cm/s and the spores on the reef surface can be attached and grown.
6 Water temperature: Pay attention to the sea area where the water temperature does not exceed 27°C in summer.
(3) Kelp proliferation method:
1 Spore Propagation Proliferation: Artificially attach spores to stones and re-inject them into selected sea areas. The size of the stones depends on the size of the storm. Cast stone per acre.
2 Submerged species of seaweeds law: the preservation of species of kelp over the summer, until the fall of the mature sporangia and transported to the selected area of ​​the sea, the species with a dry stimulation for 2-3 hours, and then tied with rope tied at both ends of the stone anchor pull Tightly put into the sea. There are 1,000 trees per mu.
3 Suspension rope seedling proliferation method: Japan adopted this method, that is, in the selected sea area first to set up the sea floor floating raft. Hang the seedlings on the floating trusses to allow them to naturally disperse the spores. Attached to the rocky reef.
