Seaweed organic fertilizer and preparation method thereof

Abstract

The invention discloses a seaweed organic fertilizer, which comprises following materials by mass percent: 40% to 70% of seaweed concentration stock solution formed by concentrating fresh seaweed, 1% to 6% of vitamin K1 derivatives, 28% to 50% of biological fulvic acid and 1% to 4% of aseptic. Simultaneously, the invention further discloses a preparation method for the seaweed fertilizer, which comprises the following steps of (1) utilizing a rotary harvest method to harvest fresh seaweed; (2) cleaning the harvested fresh seaweed, removing residues, smashing, pulping, obtaining coarse liquid through low temperature high pressure cell rupture technology, then filtering, and concentrating the seaweed concentration stock solution; and (3) preparing the vitamin K1 derivatives and the biological fulvic acid, and adding the aseptic and the seaweed concentration stock solution to obtain the seaweed organic fertilizer. The seaweed organic fertilizer can improve soil, promotes crop root systems to be developed, greatly reduces pesticide using amount and is environmental-prevention and safe.

Description

technical field [0001] The invention relates to a seaweed organic fertilizer and a preparation method thereof, in particular to a seaweed organic fertilizer which improves soil and promotes the development of crop root systems and a preparation method thereof. Background technique [0002] my country is one of the countries with the richest seaweed resources in the world, and it is also the country with the largest annual output of artificially cultured seaweed. At present, there are more than 100 kinds of large-scale economic algae in my country, and the resources are very rich. Due to the special growth environment of seaweed, it contains the types and contents of active ingredients that terrestrial plants cannot match, such as seaweed polysaccharides, vitamins, minerals, natural plant hormones, etc. [0003] Domestic seaweed is widely used in medicine, food and other industries, but less in agriculture. However, with the development of society, human beings have hig...

Problems solved by technology

[0004] However, there are two problems with domestic seaweed fertilizer products: first, the main raw materials of real seaweed fertilizers come from seaweed, and only coastal areas in the country have planting and production

These seaweed fertilizer patent technologies have two problems: first, the lack of research on the selection of raw materials, resulting in product quality safety issues and unstable quality; the source of seaweed plays a decisive role in the quality and efficacy of seaweed fertilizer, different Types, seaweeds in different waters have different nutrient contents, and different harvest periods have different types of active substances in seaweeds, which have a great impact on crop growth

Second, there is a lack of qualitative and quantitative analysis of the active ingredients of seaweed raw materials, and the products produced are crude products, which can only vaguely describe the product functions, and cannot obtain high-end seaweed fertilizer products with clear functions and stable quality, and the economic value of the products cannot be improved.

Therefore, there is still a lack of high-end and high-quality seaweed fertilizers with clear functions in the domestic market.
