1, kelp local name kelp cabbage, kombu. Morphological characteristics of the leaf blade like a broadband, the tip of the narrowing, generally 2 to 4 meters long, 20 to 30 centimeters wide (in the seabed growth of kelp smaller, 1 to 2 meters long, 15 to 20 centimeters wide). Leaf margins are thin and soft, wavy folds, the leaf base is a short columnar petiole connected to the fixer (pseudopetiole). The kelp is olive-brown in color, turning dark brown and black-brown after drying, with white powdery salt stains. Place and season of production It is cultivated along the coasts of Liaoning, Shandong, Jiangsu, Zhejiang, Fujian and the northern part of Guangdong Province in China. Due to the influence of temperature difference from north to south, light and other factors, so that the growth of kelp maturity early and late, in the same sea area or the same seedling rope L kelp, its maturity is also sequential, so the harvest period from mid-May continued to early July. Economic value of kelp is a high nutritional value of vegetables, per 100 grams of dried kelp contains: crude protein 8.2 grams, 0.1 grams of fat, 57 grams of sugar, 9.8 grams of crude fiber, 12.9 grams of inorganic salts, 2.25 grams of calcium, 0.15 grams of iron, as well as 0.57 milligrams of carotene, thiamine (Vitamin B1) 0.69 milligrams of riboflavin (Vitamin B2) 0.36 milligrams of niacin, 16 milligrams. 16 mg, can issue 262 dry calories. Compared with spinach, rape, in addition to vitamin C, its crude protein, sugar, calcium, iron content are several times higher, dozens of times. Kelp is a seaweed with high iodine content. Cultured kelp generally contains iodine 3-5% 0, as much as 7-10 flood. The iodine and fucoidan extracted from it are widely used in medicine, food and chemical industry. Iodine is one of the essential elements of the human body, iodine deficiency will suffer from enlarged thyroid line, eat more kelp can prevent and cure this disease. It can also prevent arteriosclerosis and reduce the accumulation of cholesterol and lipid. Kelp export species, its English name is sea belt, to countries and regions: Japan. 2, wakame Brown algae phylum, brown subclass, kelp order, winged algae, wakame genus wakame in our country in the Song Dynasty, "the Materia Medica" on the said swiss chard, sound into wakame. In addition, the leaf blade of this seaweed is pinnatifid, which is very similar to kelp, so it is named. Characteristics Undaria pinnatifida is a temperate seaweed, which can tolerate high water temperature. Undaria pinnatifida grows naturally in China, mainly in Zhoushan Islands and Shengsi Islands in Zhejiang Province. Nowadays, wakame is also found in Qingdao and Dalian, which is actually transplanted from North Korea and Japan in the early years. The spore body of wakame is yellowish brown, resembling a broken banana leaf fan, 1-2m high and 50-100cm wide, and is obviously divided into three parts: the fixer, the stalk and the leaf blade. The fixator is composed of forked branched pseudoroots, the end of the pseudoroots is slightly thicker to fixate on the rocky reef, the stalk is slightly longer, flattened and rounded with a slightly elevated center, the middle part of the leaf blade has a middle rib that comes from the elongation of the stalk, and pinnate lobes are formed on both sides. There are many small black spots on the leaf surface, which are the openings of the mucous gland cells to the surface. The internal structure is very similar to that of kelp. On both sides of the stalk of the growing sporangium, fungus-like overlapping folded sporangia are formed, and at maturity, sporangia are formed on the sporangia. The life history of wakame is very similar to that of kelp, also alternating generations, but the sporophyte growth time is shorter than that of kelp, close to one year (kelp grows for close to two years), while the gametophyte growth time is longer than that of kelp, about one month (kelp gametophyte growth is generally only two weeks). Wakame contains a variety of nutrients, according to preliminary analysis of each 100 grams of dried products containing 11.6g of crude protein, 0.32g of refined fat, 37.81g of sugar, 18.93g of ash, but also contains a variety of vitamins, crude protein content is higher than the kelp, and its taste is also more than the kelp. Wakame is not only a kind of edible economic brown algae, and can be used as comprehensive utilization of raw materials for extraction of alginate. 3, purslane altar purslane (porPhyra haitanensis) belongs to the red algae (ribedophyta), the original red algae (Protonorideae), red cabbage (Bangiales), red cabbage (Bangiaeeae), purslane genus. In its life history, the plant has two distinct developmental stages, namely, the filamentous body and the chloroplast stage. The filaments are so small that they can only be observed with the naked eye in dense clusters. The morphology of the filamentous body is distinctly different at different stages of development, and the filamentous body stage is usually divided into five periods, i.e., germination of fruit clusters, growth of the filamentous algal body, formation of expanded algal filaments, formation of shell clusters, and dispersal of the shell clusters. Foliar body is divided into leaf, petiole and fixation of three parts (see Figure 1 a 5), the leaf blade is linear lanceolate, the base is broad, the tip of the gradual loss of leaf thin like membrane, the edge of the few wrinkles, natural growth of 30 ~ 40 cm long, 3 a 5 cm wide, artificial culture of the leaf length of up to 1 a 2 meters. 4, stone cauliflower stone cauliflower, also known as sea jelly cabbage, red silk, phoenix tail, etc., is a kind of red algae. It is transparent, like jelly, taste sharp and crisp, can be mixed with gazpacho, but also made of cold powder. Stone cauliflower is also the main raw material for refining agar. Agar, also known as agar, agar, agar, is an important plant gum, belongs to the fiber class of food, can be dissolved in hot water. Agar can be used to make cold foods, jellies or culture media for microorganisms. Stonecrop can absorb water in the intestines, make the intestinal contents swell, increase the volume of stool, stimulate the intestinal wall, and cause bowel movements. So people who are often constipated can consume some stone cauliflower appropriately. Stone cauliflower is rich in minerals and a variety of vitamins, especially the fucoidan substances it contains have antihypertensive effect, the starch sulfate lipids contained in polysaccharides, with lipid-lowering function, hypertension, hyperlipidemia has a certain effect on prevention and treatment. Chinese medicine believes that stone cauliflower can clear lungs and phlegm, clear heat and dry dampness, nourish yin and fire, cool the blood to stop bleeding, and have the effect of summer heat. 5, Ulva stone Ulva (Ulva lactucal.) belongs to the green algae (Chlorophyta), green algae, filamentous algae (Ulotrichales), Ulva, Ulva family, Ulva genus, also known as the sea cabbage, sea green cabbage, sea lettuce, green cabbage, mossy cabbage, spandex, common seaweed. Sheet-like, nearly ovate blade body consists of two layers of cells, 10-40 cm high, bright green, the base to fixation device fixed on the rock, living in the coastal intertidal zone. 6, sargassum sargassum alias grass cress, sea cress, belongs to brown algae (phaeophyta) inkhorn algae (Fueales) sargassum family sargassum genus (S argassum), the algae body yellowish-brown, the main stem is very short, on the birth of 1 a 2 primary branches. Lateral branches alternate, in the same plane as the leaves. Leaves without midrib, asymmetric, one side curved outward, leaf margin coarsely toothed. Fixation apparatus rhizomatous. Air sacs ellipsoid or fusiform or with spinelike crowns or toothed projections, sometimes the margins or tips of the air sacs are winged. Reproductive receptacle terete. Dioecious. Mainly grows in the low tide line near and below a meter or so on the rocks, in the low tide zone in the larger stone marsh also has some growth [5], in China, mainly produced in the East China Sea, the South China Sea coast, resources are quite rich. 7, antler vegetable Name: hornwort Source: for the algae plant medicine cedar algae family plant hornwort grass.
