Method for preparing functional alga fertilizer through co-fermentation of multiple strains

Abstract

The invention discloses a method for preparing a functional alga fertilizer through co-fermentation of multiple strains. By employing the multiple-strain co-fermentation manner, macro-molecular substances difficult to utilize are degraded into micro-molecular polysaccharide, monosaccharide and nitrogen-containing compounds, and also a large amount of soil beneficial bacteria and multiple special-efficacy metabolites are generated, so that the biological activity of the alga fertilizer is improved and the production cost for producing the alga fertilizer by employing a biological fermentation process is reduced. According to the method, the destroying effects caused by strong base, high temperature and high pressure in the production process of the alga fertilizer are avoided, alga macro-molecular substances are degraded by various enzyme systems generated in the microbial fermentation metabolism process, and abundant nutrients in alga are fully kept. The product provided by the invention has an organic matter content of 45% or more, is abundant in trace elements such as iodine, manganese, boron, selenium and the like, and has the efficient live bacteria number of 200 million / g or more. According to the product, natural nutrient compositions, antibiotics and phytohormone are integrated, and the product has the composite efficacy of combining four fertilizers such as an inorganic fertilizer, an organic fertilizer, a microbial fertilizer and a trace-element fertilizer into one fertilizer and combining pesticides and fertilizers into one product, and has wide application prospect.

Description

technical field [0001] The invention relates to a method for preparing functional seaweed fertilizer by multi-bacteria co-fermentation of seaweed, which belongs to the field of fertilizer production. Background technique [0002] Seaweed is a rich source of marine organisms, widely used in food, industrial raw materials, and herbal medicines. Seaweed has been used in agriculture and livestock production for centuries. Seaweed fertilizer is a new type of pure natural, non-toxic and side-effect fertilizer. It contains rich non-N organic matter and a certain amount of amino acids, proteins and micronutrients, and also contains seaweed polysaccharides, alginic acid, and alginic acid unique to marine organisms. Unsaturated fatty acids and mineral elements such as zinc, bromine and iodine, which are rare in terrestrial plants, and rich in vitamin C and B 1 , B 2 , B 12 , D, E, K and other nutrients have the functions of increasing crop yield, improving quality and enhancing cr...

Problems solved by technology

However, there are still many defects in the preparation of seaweed fertilizers by biological fermentation methods. One is that the fermentation microorganisms are single, and the enzymes produced are single, which makes it difficult to truly degrade the macromolecules of seaweeds, which affects the effect of seaweed fertilizers. The second is the biological fermentation method. In the preparation of seaweed fertilizer, the use of microbial fermentation strains has no beneficial effect on the soil, which simply increases the production cost

Therefore, at present, most enterprises that use biological fermentation to produce seaweed fertilizers use the compound method of adding acid and alkali at the same time, which has the disadvantages of destroying and losing nutrients such as active factors in seaweed.
