Abstract
The invention discloses a preparation method of seaweed amino acid microbial fertilizer. The preparation method comprises the following steps: (1) pulverizing seaweed, adding water and a fermentation accelerator into the seaweed, sterilizing the mixture at a temperature of 120-125 DEG C for 20-30min, cooling the mixture to the room temperature, adding a composite strain into the mixture, carrying out fermentation on the mixed solution at 25-30 DEG C for 3 to 5 days, and adjust the pH value to 7.5-8.0, and (2) orderly adding urea and/or potassium dihydrogen phosphate and chelating trace elements into the solution obtained in the step (1) along with stirring and then carrying out stirring for 20 to 45 minutes to obtain the seaweed amino acid microbial fertilizer. Through the highly active microbial agent, the seaweed is subjected to deep fermentation so that natural active ingredients in the seaweed are greatly retained, and the natural active ingredients and chelating trace elements are blended so that fertilizer nutrients and a fertilizer utilization rate are increased. The seaweed amino acid microbial fertilizer is novel bioremediation and soil regulation seaweed microbial fertilizer according with animal, plant and microbial ecological balance.
Description
Technical field
The present invention relates to bio-fertilizer technical field, more particularly to a kind of preparation method of algae amino acid microbial fertilizer.
Background technology
In recent years, with expanding economy, to living environment and the attention degree more and more higher of quality of life, food-safety problem is also increasingly subject to all sectors of society extensive concern to people.These changes propose challenge to original Agriculture Production Modes, and finding new, agricultural measures that are meeting agricultural sustainable development needs becomes the focus of current agricultural PRODUCTION TRAITS.
All the time, fertilizer practice is to ensure one of important means that agricultural production is smoothed out.But the Long-Time Service and unreasonable measures of fertilizer of a large amount of inorganic fertilizer can cause the fertilizer pollution in agricultural product, make Grain Growth Situation not good enough, the ability of opposing harmful organism declines, increase the usage amount and number of times of agricultural product production process Pesticides, the quality of agricultural product is reduce further, makes crops Pesticide Residues exceeded, the accumulation of soil noxious material, agricultural environment pollution aggravates, and human and livestock health is constituted a threat to safely.
Marine alga is the low phototrophy plant being grown in ocean, is the original producer of marine organisms.In ocean in this special environment, it in addition to the nutrition having containing land plant, also rich in trace elements such as potassium, iodine, manganese, and miscellaneous vitamin.Special composition algal polysaccharides in marine alga can not only chelate the harmful substances such as the heavy metal ion in soil, and can also increase the venting capability of soil, soil is difficult by erodsion losses such as wind, current.
People have carried out substantial amounts of research to marine alga, have developed substantial amounts of marine alga series fertilizer.The method of existing production marine alga, usually chemical method, are exactly processed marine alga using strong acid and strong base under HTHP drastic conditions, and this method technique is complex, and condition is harsh, and destroys the substantial amounts of active ingredient in marine alga.
The content of the invention
The technical problem to be solved is：In view of the shortcomings of the prior art, there is provided nutrition is complete in a kind of simple production process, the active ingredient that will not be destroyed in marine alga, fertilizer, environmental protection algae amino acid microbial fertilizer preparation method.To solve above-mentioned technical problem.
The technical scheme is that：A kind of preparation method of algae amino acid microbial fertilizer, comprises the following steps：
(1) marine alga is crushed, add the water of 1～5 times of volume of the marine alga, and the fermentation accelerant with marine alga same volume, it is 120～125 DEG C of 20～30min of sterilizing in temperature, room temperature is dropped to, adds composite bacteria, the content of fermentation accelerant and composite bacteria in mixed solution to be 0.5～5wt%, mixed solution is fermented 3～5 days at 25～30 DEG C, it is 7.5～8.0 to adjust pH value.
(2) urea, potassium dihydrogen phosphate and chelated microelements are sequentially added in the solution obtained to step (1) under stirring, the content for adding latter three is followed successively by 5～25wt%, 5～30wt% and 0.1～5wt%；Or urea or potassium dihydrogen phosphate and chelated microelements are sequentially added, add urea or the content of potassium dihydrogen phosphate and chelated microelements to be followed successively by 5～25wt% or 5～30wt% and 0.1～5wt%；Then 20～45min is stirred, liquid alga amino acid microorganism fertilizer is obtained.
Or, after the solution that step (1) is obtained is filtered, urea, potassium dihydrogen phosphate and chelated microelements are sequentially added in the solution for obtaining to step (1) under stirring again, the content for adding latter three is followed successively by 5～25wt%, 5～30wt% and 0.1～5wt%；Or urea or potassium dihydrogen phosphate and chelated microelements are sequentially added, add urea or the content of potassium dihydrogen phosphate and chelated microelements to be followed successively by 5～25wt% or 5～30wt% and 0.1～5wt%；Then 20～45min is stirred, then is adsorbed with plant ash, turf or peat soil, solid algae amino acid microbial fertilizer is obtained.Wherein, 100 mesh are ground into when the marine alga is crushed.
Wherein, the fermentation accelerant is at least one in beef extract, peptone, corn flour, beancake powder, purple perilla juice and bamboo vinegar liquid.
Preferably, the fermentation accelerant is beef extract, peptone, corn flour, beancake powder, purple perilla juice and bamboo vinegar liquid, wherein beef extract: peptone: corn flour: beancake powder: purple perilla juice: the weight ratio of bamboo vinegar liquid is 1～2：0.2～0.5：5～：1～3：0.1～0.2：0.5～1.When fermentation accelerant be two kinds therein or it is two or more when, the percentage by weight that adds of each fermentation accelerant component is suitable for it all plus fashionable corresponding addition ratio.
The composite bacteria includes volume ratio 1：1：1～2：1～2 actinomyces, photosynthetic bacteria, ferment bacterium and bacillus.
As a result of above-mentioned technical proposal, the invention has the beneficial effects as follows：
The present invention is with marine alga as raw material, submerged fermentation is carried out to marine alga using high-activity microorganism microbial inoculum, active ingredient in marine alga is completely dissolved out, without any strong acid and strong base, greatly remain the natural activity active ingredient in marine alga, such as amino acid, algal polysaccharides, mannitol and iodine, potassium, magnesium, manganese, the trace elements such as titanium, the bacillus of present invention addition, the thalline such as ferment bacterium itself synthesize α-amylase, protease, lipase, the enzymes such as cellulase, rupture alginic cell wall, dissolving, active ingredient in marine alga is discharged completely, bacillus subtilis can also secrete antibacterial material, suppress the growth of harmful bacteria, and then promotion plant growth, photosynthetic bacteria can increase the photosynthesis of plant, improve the cold-resistant of crop, the resistance such as drought resisting；The present invention and chelated microelements compatibility, significantly improve the nutrient and utilization rate of fertilizer, thus made by algae amino acid microbial fertilizer nutrition it is complete, the material containing various promotion plant growths.
