1. It can usually be divided into chemical hydrolysis method (i.e. potassium hydroxide hydrolysis method), physical extraction method, biological fermentation method (i.e. enzymatic degradation method), etc. There are also biological active substances extracted from waste from the seaweed industry, and then scientifically Formulated fertilizer.
2. The extraction method has a great influence on the content of active substances and nutrients in the product. Even if the content of nutrients is the same, the content of active substances may be very different.
3. If the active ingredients of seaweed can maintain their original state to the greatest extent, the use effect will be better. Currently, the best way to produce seaweed organic fertilizer is cold cell rupture technology. This technology can maintain the activity of seaweed active substances to the greatest extent. , followed by biodegradation method, which can preserve the activity of active substances very well, while chemical hydrolysis method is poor.
4. At present, most manufacturers at home and abroad mainly use chemical hydrolysis method to produce seaweed fertilizer. The biggest disadvantage of chemical hydrolysis method is that strong alkali and high temperature destroy the activity of endogenous substances in seaweed. There are many such products, such as those produced by small domestic manufacturers. Cheap seaweed fertilizer.
5. The principle of biological fermentation is to use a variety of enzymes produced by microorganisms during the metabolic process of using seaweed as nutrients to degrade the macromolecular substances that make up seaweed into small molecules and water-soluble substances. Since there is no chemical method in the fermentation process Strong alkali and high temperature can very well preserve the activity of the active ingredients in seaweed. Some seaweed fertilizers imported from Ireland, Norway, etc. are produced using this method.
6. The physical extraction method uses a differential pressure cold cell blasting process to achieve the purpose of crushing the seaweed cell wall. It can preserve the activity of the active ingredients in the seaweed cell liquid as it is, and maximize the effectiveness of seaweed fertilizer. The entire production process does not Add any foreign substances. The seaweed fertilizer produced in this way is of excellent quality.
