Description
Technical field
The invention belongs to the manufacturing field of organic fertilizer and organic fertilizer, be specifically related to a kind of marine alga organic liquid fertilizer and preparation method thereof.
Background technology
In marine algas such as sea-tangle, bulk kelp, bladder wrack, extra large capsule algae, kelp, be rich in the useful various inorganicss of crop growth, organism and many biologically active substances, be extraordinary agricultural fertilizer.The be applied to fertilizer of marine alga on agricultural is had a long history, many in the world maritime nations just gather marine alga a long time ago and manufacture compost, are about to pile up in heaps or be embedded in the heatable adobe sleeping platform because of stormy waves is flushed to brown alga on the seashore, make its spontaneous fermentation, make seaweed fertilizer, its agricultural produce effect is obvious.
Under the modern industrialization condition, the production method of seaweed fertilizer generally can be divided into: chemical hydrolysis (being the potassium hydroxide hydrolysis method), physics extraction method, biological fermentation process (being the enzyme liberating method).The production method of seaweed fertilizer is very big to the influence of its active substance and nutrient composition content, has both made nutrient composition content identical, and active different its fertility differences are also very big.Domestic and international most producers mainly adopt chemical hydrolysis production seaweed fertilizer at present, adopt the shortcoming of chemical extraction method maximum to be that highly basic high temperature can destroy the activity of marine alga endogenous substance; The physics extraction method is to adopt high pressure low temperature refrigerative technology to reach the purpose of alginic cell wall fragmentation, this extracting method gained seaweed fertilizer is better than the chemical extraction method, but the high pressure low temperature environment still can destroy biologically active substance in the marine alga and nutritive substance, the fertilizer efficiency of its product is still not fully up to expectations, and physical purification technical matters complexity, cost are too high.The biological fermentation ratio juris is that to utilize microorganism be the plurality of enzymes that produces in the metabolic process of nutrient with marine alga etc., the macromolecular substance that constitutes marine alga is degraded into small molecules, water miscible material, because fermenting process does not have the highly basic and the high temperature of chemical method, the high pressure and the low temperature that also do not have the physics method, therefore intactly kept biologically active substance and the nutritive substance in the marine alga to greatest extent, helped being utilized by plant absorbing.
To sum up, the best way of production seaweed fertilizer is to adopt biological fermentation process, secondly is the physics method, and the poorest is the chemical extraction method of carrying out with strong acid or highly basic.But biological fermentation process production seaweed fertilizer also has many shortcomings: such as the fermentation difficulty of macromolecular substance such as the seaweed fiber of difficult degradation in the marine alga, alginate calcium, fucoidin, protein, pectin, general fermentation about 14 days, the time of fermenting is long, causes the production cycle long; Fermentation degree is not high, and the marine alga utilization ratio is not high, causes problems such as the environmental pollution and the wasting of resources.And the technology of biological fermentation process production seaweed fertilizer, because its technology and application mechanism are lacked deep systematic study, only limit to both at home and abroad the laboratory study stage of fumbling at present, the preparation technology of mature and feasible is not applied to large-scale production.
Present various seaweed fertilizer are because the limitation of production technique separately, and the available nutrient content of seaweed fertilizer is not high, and wherein active substance lacks, and causes fertility not high, and effect is bad.
Summary of the invention
The objective of the invention is defective, provide a kind of fermentation fast, with short production cycle at above-mentioned prior art, the attenuation degree height, and the biological fermentation process of suitable large-scale production prepares the method for marine alga organic liquid fertilizer.
