First, seaweed fertilizer and its role. Seaweed fertilizer is a natural organic fertilizer, and its fertilizer effect depends on the nutrients contained in the seaweed fertilizer. Seaweed used as a fertilizer is generally a large-scale economic algae, such as macroalgae, seaweed, sea cyanobacteria, and the like. The development of seaweed has gone through three stages: decaying seaweed → seaweed ash (powder) → seaweed extract. The core substance in the seaweed fertilizer is pure natural seaweed extract, and the main raw material is selected from natural seaweed. After a special biochemical process, the essence extracted from the seaweeds retains the natural active ingredients and contains a large amount of non-nitrogen-containing organic matter and over 40 kinds of mineral elements such as potassium, calcium, magnesium and iron that are unmatched by terrestrial plants. And rich in vitamins, especially containing algae polysaccharides, alginic acid, highly unsaturated fatty acids and a variety of natural plant growth regulators unique in seaweed, have a high biological activity, can stimulate the production of non-specific active factors in plants, Regulates the balance of endogenous hormones. Second, the study of foreign seaweed organic fertilizer. In the 16th century, the British expanded their use of seaweed to make fertilizers. In Japan, France, and Canada, the practice of collecting seaweed for composting was very early. In the 17th century, the French government strongly recommended the use of seaweed as a soil fertilizer in coastal areas, and explicitly specified the conditions for seaweed harvesting, harvesting time, and sea areas. To date, overseas application of seaweed fertilizer has conducted comparative tests on potatoes, corn and a series of crops, fruits and vegetables. Seaweed fertilizer has matured crops earlier, increased yield and improved quality, and has produced obvious effects on fruit preservation and resistance to pests and diseases. The effect can increase production by 10-30%. In 1984, horticulturists in South Africa conducted experiments on different types of flowers, which proved that seaweed fertilizer not only promotes early flowering, but also significantly increases the number of flower buds, with an increase rate of 30-60%. According to a report from a slow university in Japan, the application of seaweed essence to the debilitating orange can promote shoot growth, increase the number of new shoots, number of stem leaves, leaf area and leaf fertilizer; observation of leaf section under a microscope reveals that starchy photosynthetic The product accumulated in a large amount in the mesophyll cells, indicating that plants can absorb nitrogen from the shoots to promote photosynthesis and produce a large amount of starchy photosynthetic products, restore tree vigor, promote growth, improve quality, and increase yield. Seaweed extract is used as an organic biological hormone in foreign countries. It is also commonly used in nursery and flower and lawn production. U.S. researchers conducted experiments in the greenhouse, using peat and vermiculite as a cultivation medium, sow 19 varieties of flowers and vegetables, and in the first true leaf stage, sprayed with seaweed fertilizer leaves, compared with the control, the treatment germinated early. The root length is long and strong. Seaweed fertilizer can also increase the yield of marigold. Compared with the control group, the first true leaf treatment can increase grain growth by 31.5% to 32.2% and promote early flowering.
