The main raw materials are selected from natural seaweed. After special biochemical treatment, seaweed essence is extracted, which greatly retains natural active ingredients. It contains a lot of non-nitrogen-containing organic matter, more than 40 mineral elements such as potassium, calcium, magnesium, zinc and iodine, and rich vitamins, especially seaweed polysaccharide, alginic acid, highly unsaturated fatty acids and various natural plant growth regulators. It has high biological activity and can stimulate plants.
After special treatment, the effective components in seaweed fertilizer are in an active state that can be easily absorbed by plants, and enter plants within 2-3 hours after use, with fast absorption and conduction speed. Seaweed fertilizer contains natural plant growth regulators, such as auxin, cytokinin, gibberellin, etc., which have high biological activity, and the proportion of various substances is similar to that of hormones in terrestrial plants. Alginic acid in seaweed fertilizer can reduce the surface tension of water, form a film on the surface of plants, increase the contact area, make water-soluble substances enter plant cells more easily through the cell membrane on the surface of stems and leaves, and make plants absorb nutrients in seaweed extract most effectively. Therefore, if seaweed liquid fertilizer is mixed with pesticides, fungicides and chemical fertilizers, the effect is better, the spraying cost can be reduced, and there is a synergistic effect on pesticides and chemical fertilizers. It is reported abroad that natural antibiotics contained in alginic acid have antiviral effect. The raw material of seaweed fertilizer is selected from natural seaweed, which has good affinity with terrestrial plants, is harmless to people and animals, and has no pollution to the environment, and has incomparable advantages over any other fertilizer.
Seaweed fertilizer can increase soil organic matter directly or through plants, activate various beneficial microorganisms in the soil, and these microorganisms can play a catalytic role in the cycle of plant-microbial metabolites, thus increasing the bioavailability of soil. Metabolites of plants and soil microorganisms can provide more nutrients for plants. Seaweed fertilizer is a natural biological agent, which can coexist harmoniously with plant-soil ecosystem. Natural compounds such as sodium alginate are natural soil conditioners, which can promote the formation of soil aggregate structure, improve the internal pores of soil, coordinate the proportion of solid, liquid and gas in soil, restore the natural gum balance lost due to excessive soil burden and chemical pollution, increase soil biological activity, promote the release of effective nutrients, be beneficial to root growth and improve crop stress resistance.
