Abstract
The invention provides a production method of a natural organic seaweed fertilizer. The method comprises the following steps: treating seaweeds by using a method of combining mechanical crushing centrifugation with chemical alkali digestion, washing the digested slurry material with water and performing filtration and concentration so as to obtain a corresponding semi-solid filter material; compounding the dried filter material; and producing the compounded filter material by using a granulating process so as to obtain the organic seaweed fertilizer. According to the method, a relatively small amount of alkali is added and an enzyme agent is not used, i.e., and the increasing of the additional cost is avoided, so that the requirement on the working environment of a reaction kettle is relatively low. The produced organic seaweed fertilizer contains a large quantity of organic substances without containing nitrogen and multiple mineral nutrients such as potassium, magnesium and zinc, and particularly contains seaweed polysaccharides and highly unsaturated fatty acids which are specifically contained in the seaweeds and is rich in multiple plant growth regulators such as cytokinins and auxins, thereby having the high biological activity. Thus, the absorption and the growth of plants are promoted by the beneficial substances from the seaweed plants. As a result, the stress resistance of crops is improved; the yield of the crops is increased.
