Morphological characteristics Curly into a group, 蔌 tangled into the handle. The whole body is dark brown or greenish brown with white frost on the surface. When immersed in water, it swells into a flat long strip, 50 to 150 cm long, 10 to 40 cm wide, thicker in the middle, and thinner and wavy at the edges. Leathery, remaining stalks oblate. Dizzy, taste salty. 1. The kelp is olive brown in color and dark brown in color after drying. After maturation, the leathery material is banded and is generally 2-6m long and 20-50cm wide. There are two parallel shallow grooves in the center of the blade. The middle part of the two grooves is the “middle band†with a thickness of about 2- 5mm, both sides of the edge gradually thin, and corrugated folds, the base of the leaf blade is wedge-shaped, the thickness of the stage is flat and round, under a cylindrical or flat round short handle, 5-15cm long, the handle and the inside of the blade by It consists of the pith, cortex and epidermis. In the outer layer there is a mucus cavity, and there are secretory cells in the cavity, which can secrete mucous to the surface of the leaves, form a glial layer, and make the algae body stick and play a protective role. The pith is composed of many algae filaments, and the cells of the algae are bulged at one end to form a trumpet tube. The leaf surface of the algae was smooth in young stage, and the convex and concave leaves appeared in the leaves of small kelp. In the lower part of the annual algae leaves, the sporangia can usually be seen growing in a nearly round shape; the algae in the second year grow sporangia on almost all the leaves. The anchor is composed of a forked branch of a pseudo-root. Spores mature during the fall. 2. Black algae dark brown to dark brown algae, leathery, high 30-100cm or more. The fronds are broadly flattened and slightly thickened in the middle, with one or two feathers deep on both sides. The lobes are long or slightly longer, slightly wrinkled, and the edges are usually coarsely serrated. Stems petiolate, cylindrical or slightly flat, 4-12cm long, 3-8mm in diameter. The cortical cells of the algae are arranged in a circular arrangement with mucous cavities, which are 1-2 layers. The pith is made up of an indefinitely trending trumpet wire. The sporangial population forms on the surface of the mature lobe central part and lateral lobes. The anchor is composed of a pseudo-branched bifurcated root. Sporangia form in early summer and spores mature in autumn. 3. Wakame is a yellow-brown algae, soft leathery, 1-2m high, 50-100cm wide, flat fronds, medium ribs with prominent bulge in the middle, gradually thin and soft on both sides, forming most feathery lobes, or not sized Qi's absence, but no jaggies. Many small black spots are scattered on the leaf surface, opening the mucous cells to the epidermis. When mature, spores with overlapping ears and folds of fungus were found on both sides of the lower part of the petiole, and the spores were densely sclerotized. The fixer consisting of a forked branch of the pseudoroot at the lower end of the petiole.
