Five characteristics of seaweed fertilizer
1. Seaweed fertilizer is more comprehensive than traditional fertilizers. After crop application, the growth is balanced, the yield increase effect is remarkable, and there is very little deficiency syndrome.
The seaweed fertilizer uses natural seaweed as the main raw material, and contains a large number of natural bioactive substances extracted from seaweed, which are beneficial to plant growth and development, and mineral nutrients absorbed by seaweed from the sea and enriched in the body, including seaweed polysaccharides and phenols. Poly compounds, mannitol, betaine, plant growth regulators (cytokinins, gibberellins, auxins, abscisic acid, etc.) and nitrogen, phosphorus, potassium and trace elements such as iron, boron, molybdenum, iodine. In addition, in order to increase the efficiency of fertilizer and the chelation of fertilizers, some products also dissolve the proper amount of humic acid and appropriate trace elements to meet the nutritional needs of various stages of crop growth.
2. Seaweed fertilizer contains a large number of anti-disease factors and special ingredients, and the drug is double-effect. After the application of crops, the resistance to stress is significantly enhanced, and foliar application can improve the effect of pesticides.
Seaweed polysaccharides contained in seaweed fertilizer, oligosaccharides, mannitol, phenolic poly-compounds, betaine, alginic acid and natural antibiotics, have significant antibacterial, anti-viral and deworming effects, and truly play a role in fertilizer It greatly enhances the cold resistance, drought resistance, disease resistance, lodging resistance and salt and alkali resistance of crops, and produces strong resistance to diseases, viral diseases, anthrax, downy mildew, gray mold, powdery mildew and blight. In addition, 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 easier to penetrate into the plant cells through the cell membrane on the surface of stems and leaves, so that plants can absorb most effectively. The nutrients in the seaweed extract. If the seaweed fertilizer is mixed with insecticides and fungicides, it has synergistic effect and can reduce the spraying cost.
3. Seaweed fertilizer contains a large amount of high active ingredients, which are easily absorbed by plants. After crop application, the growth is strong, which can significantly improve the yield and quality of crops.
Seaweed polysaccharides, alginic acid, highly unsaturated fatty acids and other substances unique to seaweed have high biological activity and can stimulate the production of non-specific active factors in plants. At the same time, seaweed fertilizer also contains natural plant growth regulators, such as: auxin, cytokinin and gibberellin, the proportion of which is similar to the proportion of hormones in terrestrial plants, and has a good regulation of endogenous hormone balance. effect. After crop application, the yield and quality were significantly improved, leafy vegetables increased by more than 20%, and grain crops increased.
More than 15%, fruit trees increase production by 10% to 30%, while increasing the number of first-grade fruit to more than 80%, can significantly improve the quality of tobacco, cotton, flowers and other economic crops, especially for greenhouse vegetable crops, the effect of increasing production and value is very significant .
4. Seaweed fertilizer is rich in organic matter and slow release factor, and has long fertilizer effect, which can improve soil micro-ecology, promote soil rooting and resist heavy mites.
Seaweed fertilizer can directly increase soil organic matter through soil or through plants, and activate various beneficial microorganisms in the soil. These microorganisms can act as catalysts in plant and microbial metabolic cycles.
Increase the biological effectiveness of the soil. Plant and soil microbial metabolites provide plants with more nutrients. At the same time, the chelation system formed by seaweed polysaccharide can release nutrients slowly and prolong fertilizer efficiency. In addition, it contains natural compounds such as sodium alginate, which is a natural soil conditioner that promotes the formation of soil aggregate structure, improves the pore space inside the soil, coordinates the ratio of solid, liquid and gas in the soil, and restores the soil due to excessive burden. The natural gelatin balance lost by chemical pollution increases the biological vitality of the soil and promotes the release of available nutrients, which is beneficial to root growth and improve the stress resistance and resistance of crops.
5. Seaweed fertilizer is natural and safe.
Traditional chemical fertilizers have a single effect and serious pollution, and long-term use can lead to the destruction of soil structure.
Seaweed is a natural seaweed extract. It has good affinity with terrestrial plants. It is non-toxic and harmless to humans and animals. It has no pollution to the environment. It has the advantages that no other chemical fertilizer can match. It is listed as organic in foreign countries. Special fertilizer for food. Seaweed fertilizer aggregates a variety of active substances in the ocean, and has many advantages such as comprehensive nutrition, disease resistance, increased production, live soil, pollution-free, etc. It is a good fertilizer that truly conforms to the direction of modern agriculture.
