Description
Technical field
The present invention relates to a kind of making method of fertilizer, specifically relate to a kind of making method of seaweed manure.
Background technology
In recent years, because chemical fertilizer and the unreasonable in a large number of chemical pesticide are used, not only consume a large amount of Nonrenewable resources, and destroy Soil structure, pollute quality of agricultural product and environment, have impact on the health existence of the mankind.China's year fertilizer application amount more than 4,000 ten thousand tons, long-term a large amount of use chemical fertilizer and using method improper, the destruction that farmland ecological environment, soil physico-chemical property and soil microorganisms flora are subject in various degree can be made.By excessive, solely use the adverse consequences that chemical fertilizer causes, caused the extensive concern of various circles of society.Biological organic fertilizer is as a kind of new-type fertilizer, and its research and development bring new change to the production of fertilizer and use beyond doubt.So-called biological organic fertilizer, just refers to microorganisms with specific functions and is mainly originate and have the fertilizer of microbial fertilizer and fertilizer effect through the class that harmless treatment, the organic materials that becomes thoroughly decomposed are composited concurrently with plant and animal residues (as feces of livestock and poultry, agricultural crop straw etc.).Biological organic fertilizer product is except containing higher organic matter, and also containing the microorganism with specific function, this is the essential characteristic of this series products.
Summary of the invention
The object of the present invention is to provide a kind of making method of seaweed manure, kettle algae algae-residue is split in the method utilization and function yeast combined ferment is produced.
Concrete technical solution of the present invention is:
A making method for seaweed manure, comprises the following steps:
(1) choose and split kettle algae algae-residue and function yeast bacterial classification is raw materials, by function yeast bacterial classification liquid culture in fermentor tank, until fermented liquid thalline reaches 10
8-10
10cfu/mL, for subsequent use;
(2) by splitting the function yeast bacterial classification after kettle algae algae-residue access cultivation, having carried out oxygen fermentation, having obtained tunning;
(3) by tunning successively through granulation, oven dry, cooling, screening, packaging, obtain seaweed manure finished product.
In step (1): described function yeast bacterial classification is preferably Paenibacillus polymyxa or Paecilomyces lilacinus.
Preferably, step also comprises the pre-treatment step splitting kettle algae algae-residue in (1): removed by the inorganic impurity split in kettle algae algae-residue, shakeout airing, then pulverize through pulverizer.
Preferably, the usage ratio splitting kettle algae algae-residue and function yeast bacterial classification in step (2) is as follows: 1 ton splits kettle algae algae-residue and need add 10-20kg function yeast bacterial classification.
Preferably, in step (2): kettle algae algae-residue and function yeast bacterial classification will be split and drop in stirrer and mix, and regulate raw material pH value to 6.8-7.2 in mixing process, after being mixed to even, non-variegation, release mixing raw material; Again mixing raw material is put into fermentation vat under 22-26 DEG C of envrionment temperature, adjustment mixing raw material C/N is than being 25:1-40:1, and water ratio is 50%-60%, and ventilation is 0.3-0.5m
3/ (minm
3), carry out fermentation in 10-15 days under these conditions.
Preferably, raw material pH value to 7 is regulated in mixing process; Again mixing raw material is put into fermentation vat under 25 DEG C of envrionment temperatures, adjustment mixing raw material C/N is than being 30:1, and water ratio is 55%, and ventilation is 0.4m
3/ (minm
3), carry out fermentation in 10-15 days under these conditions.
Preferably, in step (2) fermenting process: the oxygen supply of above air supply mode aerating apparatus, adopt turnover throwing machine timing agitation, control temperature of charge and be no more than 55 DEG C.
Preferably, in step (2): mixing raw material C/N ratio is that water ratio regulates by directly being added water by mixing raw material or spreading out to dry by adding urea or waste active carbon regulates in mixing raw material.
Preferably; in step (3): tunning is delivered to tablets press through travelling belt and carries out granulating; control grain through being less than 4.0mm; then 15%-20% is reduced to through rotary shelf drier oven dry to moisture; material drying sends into next screening operation through travelling belt; material naturally cooling in course of conveying, selects the screen-aperture of sieve to be 2.0-4.0mm during screening.
Advantageous Effects of the present invention is:
(1) kettle algae algae-residue water ratio is split generally at 75%-80%, although it is containing a large amount of protein, polysaccharide, VITAMIN and mineral substance, but be currently mostly used as feedstuff raw material for this algae-residue, the present invention has innovatively will be split kettle algae algae-residue and make biological organic fertilizer, make to split kettle algae algae-residue waste and be able to better utilised, increase its utility value, and reduce the production cost of biological organic fertilizer.
(2) the present invention is utilizing in the process splitting kettle algae algae-residue making biological organic fertilizer, also be added with function yeast, such as Paenibacillus polymyxa can be added, a kind of plant growth-promoting rhizobacteria, have fixed nitrogen, phosphorus decomposing, generation microbiotic, secretion plant hormone, chitinase and lytic enzyme, the feature such as can to increase soil fertility, research simultaneously finds Paenibacillus polymyxa, do not have pathogenic to humans and animals, some bacterial strain has anti-microbial activity; Paecilomyces lilacinus, can apply on more than 30 kinds of host plants, control nematode success ratio reaches 68%, has higher preventive effect to plant nematode disease, 57.8% is reached to the relative inhibition of Meloidogyne incognita Individual eggs, 60.38% is reached to the relative inhibition of nematode egg capsule hatching.And have the effect etc. of Promoting plant growth.Above-mentioned functions bacterium add the effect significantly enhancing biological organic fertilizer in right amount.
(3) the present invention produces through above-mentioned steps biological organic fertilizer organic content and living bacteria count etc. all exceed biological organic fertilizer national standard (NY/884-2012), and moisture, pH value, induced worm egg death rate and excrement colibacillus group number all meet national standard (NY/884-2012).Different from traditional farm manure, biological organic fertilizer becomes thoroughly decomposed through high temperature, not containing harmful levels of pathogens and worm's ovum, avoids farm manure and easily burns the drawbacks such as seedling, smell is smelly, disease and pest is many.
(4) less investment of the present invention, consume energy low, instant effect, and decreases pollution, create social economic value, achieve the recycling of enterprises waste.In addition, to correlative study, also there is certain reference value.
