Description
Technical field
The present invention relates to the production method of a kind of liquid Water soluble fertilizer.
Background technology
Marine alga fertilizer, with natural seaweed as raw material, processes through special biochemical process, extracts and retains marine alga natural activity
Composition, a kind of novel organic fertilizer material that refine concentrates and formed.Marine alga fertilizer has raising crop yield and quality, resists disease pest
Effect that evil and poor environment and improvement soil conserve water and soil, it is applied to agricultural production has the huge market demand with good
Development prospect.But, the quality of marine alga fertilizer to be ensured, it is necessary for getting hold of Sargassum raw material and two crucial rings of extraction process
Joint.
First, the quality of marine alga fertilizer quality depends on raw material used.At present, the raw material used by alga fertilizer manufacturing enterprise
Main based on Brown algae, including yellow tang, Thallus Laminariae (Thallus Eckloniae), Thallus Laminariae (Thallus Eckloniae), Alga Sgrgassi Enerves etc..Other algae such as Fucus Vesiculosus, Entermorpha, ulva, Kappa
Zao Dengyeyou minority enterprise with.The external alga fertilizer enterprise overwhelming majority uses Brown algae to be raw material, the most especially applies with yellow tang
The most extensively such as famous brand names such as Seasol, Maxicrop, practical function effect also indicates that yellow tang is the Sargassum raw material of high-quality.
But, China coast does not has yellow tang to be distributed, and the raw material type that domestic enterprise uses is numerous and diverse, and quality is irregular to differ, and causes Sargassum
Fertilizer product quality is very different, and even some producer is turned on the camouflage of " alga fertilizer ", directly blends alginic acid, fulvic acid, nitrogen phosphorus
Potassium etc. pretend to be alga fertilizer, have impact on alga fertilizer quality, have upset alga fertilizer market.
Secondly, the second factor of decision alga fertilizer quality is extraction process.Different extraction processes is to alga fertilizer activity
The kind of composition and content impact are huge.At present, the extracting method of Sargassum active component mainly has chemical method, Physical and life
Thing method.Chemical method processes alginic cell mainly by acid, alkali and organic solvent, makes cell clear up or endogenous substance solubilising, should
Method is simple to operate, easily realizes, and is also the method for the most most alga fertilizer manufacturing enterprises employing.But, chemistry examination
Agent is sizable to the destruction of the active material ingredients in alginic cell, and the organic reagent remained also is potential to environment
Harm.The physical environmental condition such as the principle of Physical is to control pressure, temperature, utilize mechanical force to make alginic cell crush, interior
Tolerant release.Although the method technique cleaning, environmental friendliness, but the requirement for instrument and equipment is harsh, change in reaction conditions
Acutely, relatively costly, it is difficult to realize large-scale production.Bioanalysis includes enzymic degradation and two kinds of methods of fermentable, and it is main
Wanting principle is that to destroy alginic cell wall construction macromolecular substances of degrading be the small-molecule substance that plant easily absorbs, the party
Method reaction gentleness, product diversification, whole production process safety and environmental protection is pollution-free, is preferable alga fertilizer production method.
The research utilizing Production by Microorganism Fermentation marine alga fertilizer is relatively fewer, and only a few example researchs are that selection is multiple micro-
Biological carry out Sargassum raw material is similar to compost fermentation or aerobic fermentation process, there is sweat poor controllability, and fermentation period is long,
The problems such as target product is indefinite, it is difficult to meet the unification of industrialization production requirements, stable, controlled standard, the quality of product
It is difficult to ensure.
The microbial inoculum quantity in the purity of microbial inoculum and unit mass is mainly included for the evaluation index of agricultural micro organism.Cause
This, the bacterial preparation process as prior art is usually: carry out once under the conditions of the temperature suitably survived in microorganism and pH
Fermentation technology, is equivalent to hot-house culture.
Owing to the acidifying of current soil compaction is serious, outside air temperature is changeable, and the microbial bacterial agent of hot-house culture is directly thrown
Being put in soil, cause mortality because not adapting to severe soil environment, surviving because population cannot be formed on a small quantity even if having
Effect, also cannot play the effect of microbial bacterial agent.
Summary of the invention
The technical problem to be solved is to provide a kind of water-soluble containing the liquid addicted to sugar bacillus cereus and humic acids
Fertile production method, first, use function admirable be used for degrade alignic addicted to sugar bacillus cereus degraded Sargassum, and simulate soil
Earth natural ecological environment, makes putting into after soil addicted to sugar bacillus cereus after fermentation, can quickly adapt to environment, it is ensured that survival rate；
The second, provide utilize described addicted to sugar bacillus cereus preparation addicted to sugar bacillus cereus and containing addicted to sugar bacillus cereus containing humic acid liquid
The method of Water soluble fertilizer, the method sweat is stablized controlled, and fermentation period is short, and product efficiency is notable, is suitable to large-scale production.
In order to solve above-mentioned technical problem, the present invention by the following technical solutions:
A kind of production method containing the liquid Water soluble fertilizer addicted to sugar bacillus cereus and humic acids, it is characterised in that according to following
