CATDOLL : CATDOLL: Does kelp have differentiation of roots, stems and leaves?

Does kelp have roots, stems and leaves?

No.

Kelp is a type of algae. Algae plants do not have differentiated roots, stems, and leaves. Only higher plants have organs such as roots, stems, and leaves. Strictly speaking, algae plants are a type of lower plant and do not have roots, stems, and leaves, only differentiation similar to roots, stems, and leaves.

Although kelp has a structure similar to that of roots, stems and leaves of higher plants, it can also carry out photosynthesis.

Kelp is a subarctic algae and a species unique to the North Pacific Ocean, with only a small amount distributed in the Atlantic Ocean.

Most kelp is found in the waters of the Northern Hemisphere, while kelp is less distributed in the waters of the Southern Hemisphere.

Kelp growth is affected by factors such as light, temperature and nutrients.

my country began to cultivate kelp in the 1950s and has experimented with the growth of summer seedlings, autumn seedlings, summer seedlings, spring seedlings and early autumn seedlings. After in-depth exploration and research on the growth of kelp seedlings, it can be divided into conventional seedling cultivation technology and kelp gametophyte seedling cultivation technology.

The main value of kelp

The amino acids in kelp protein are complete and in appropriate proportions, especially the eight essential amino acids for the human body, whose contents are very close to the ideal essential amino acid content pattern in protein. In addition to being used as a dish, kelp can also be processed into a variety of foods with unique flavors.

For feeding. Adding kelp powder to feed can effectively improve the nutritional structure, reduce feeding costs, increase body weight, increase egg production rate, reduce mortality, and improve the quality of breeding varieties.

Used as industrial raw material to extract fucoidan, mannitol, dietary fiber and sodium alginate from kelp.

The predecessor of Shandong Marine Aquaculture Research Institute was the state-owned Shandong Aquaculture Farm under the jurisdiction of Shandong Fisheries Bureau, which was established in Qingdao in 1950. In 1958, Shandong Fisheries Bureau changed the farm into Shandong Marine Aquaculture Experimental Farm, and in 1961 it was changed into Shandong Marine Aquaculture Research Institute. The institute is mainly engaged in the application and development of technologies such as the aquaculture of marine economic fish, shrimp, shellfish and algae, seedling cultivation, disease prevention and control, new variety cultivation and compound feed research. At the beginning of the farm, there were only 23 people, but by 1990, the institute had 228 employees, including 118 scientific and technical personnel, accounting for 51.8% of the total number of employees. Among the scientific and technical personnel, there are 11 senior professional titles, 58 intermediate professional titles and 30 primary professional titles. The organization has set up fish research room, shrimp research room, shellfish research room, feed research room, plant research room and proliferation research room. It has a collection of more than 10,000 professional books of various types, regularly publishes the internal journal "Mariculture", and has built a comprehensive seedling test production base with a water body of 1,500 cubic meters. From its establishment to 1990, the institute has won more than 40 major scientific research awards and published more than 200 papers. Among them, the kelp raft-type fully artificial aquaculture method and the agar-agar nutrient branch raft-type multi-crop aquaculture technology won the National Invention Award; the research on shrimp compound bait won the second prize of the National Science and Technology Progress Award. In particular, the promotion and application of "kelp raft-type fully artificial aquaculture technology", "kelp natural light seedling technology" and "kelp seedling and aquaculture technology" have promoted the development of kelp and kelp production.
