A research team led by Dr. Fang Tongguang, a researcher at the US Department of Agriculture Research Center, discovered that in addition to human food and medicinal purposes, kelp, seaweed, and carrageenan and other seaweed algae plants were found to be a natural green biological fertilizer. . Seaweeds contain indole organic acid group growth, cytokinin, gibberellins, phenolic polymers, betaine, abscisic acid, amino acids, mannitol, fucoidan, xylose, galactose Aldehydic acid, glucose, protein, oleic acid, linoleic acid, palmitic acid, myristic acid, arachidic acid and iodine, potassium, calcium, magnesium, zinc, copper, etc., a variety of nutrients and chemical composition content is complete, the proportion is appropriate. As a new generation of natural green multi-effect bio-fertilizers, it can be used in vegetables, fruit trees, grain cash crops, flower seedlings, and other general production increase rates of up to 20% - 40%, and use a variety of methods, can be sprayed, watered, soaked, rooted Wait, see results in two days. The increase in production of kelp juice is mainly manifested in the following aspects: (1) The mannitol contained in algae can greatly increase the water absorption capacity and chlorophyll content of crops, and the leaf area increases by more than 10%; abscisic acid regulates stomatal closure of leaves and reduces crops. Dispersion of water, can adjust fertilizer and water consumption about one-third. (B) Phenolic polymers and betaine regulate the osmotic pressure of cell fluids and chloroplasts, and protect a series of enzymes in cells that are damaged by drought, cold, and worms, and turn into active, resistant chemicals. Anti-insect, anti-fungal, anti-line networm, anti-aphid and drought resistance. (3) The combination of iodide, copper, zinc and humate in seaweed, acting on crops is a chemically stable anti-fungus bactericide. (d) Seaweed extracts combined with humates can increase soil pellet structure, increase water retention by 10 times and increase cohesion by 7 times. (5) The combination of thiol and polyphenols in seaweed participates in the redox reaction of crops, significantly improves the activity of sugar invertase and the synthesis of phosphorus-containing organic compounds, and greatly increases the sugar content of melons, fruits, vegetables, etc. . In addition, it can extend the storage period of fruits and vegetables by 10 to 30 days and extend the flowering period by 40 days.
