Description
Technical field
The present invention relates to a kind of do not have natural pond liquid stink and the high natural pond liquid fertilizer production method of fertilizer efficiency, belong to the bio-organic fertilizer technical field.
Background technology
Biogas fermentation is a kind of phenomenon that has existed several 1,000,000,000 years natures generally to take place.Anaerobically fermenting product natural pond liquid can be used as a kind of agriculture production raw material, and part replaces chemical fertilizer and agricultural chemicals.Natural pond liquid is liquid remaining behind the biogas fermentation, mainly comprises decomposing the organic and inorganic salt that discharges in the fermenting process, and as soluble substances such as ammonium salt, sylvite, phosphoric acid salt, total solids level is approximately less than 1%.Natural pond liquid not only contains micronutrient elements such as a large amount of grand nutrition elements such as abundant nitrogen, phosphorus, potassium and calcium, copper, iron, zinc, manganese, also contain rich in amino acid, vitamin B group, various lytic enzyme, certain plants hormone, disease and pest is had the inhibiting material or the factor, the effect of natural pond liquid mainly shows fertilizer efficiency, regulates plant growth and three aspects of disease and insect resistance.
But the natural pond liquid that produces behind the biogas anaerobic fermentation self has sizable pungent odour, ecotope is caused severe contamination, the amount of application that natural pond liquid as fertilizer sources is used for agriculture production is bigger, therefore, the fertilizer efficiency that embodies is relatively low, and natural pond liquid is used in the farmland for a long time in a large number, can cause soil compaction, causes serious consequences such as the crops necrosis is long.
In recent years, along with reaching its maturity of biogas technology, be that the ecology homestead rich people of tie plan the enforcement in vast rural area with biogas, biogas technology is able to promotion and application in the rural area big area, and rural methane facilities development has entered a new developing period.Admitting and transform natural pond liquid by " pig-natural pond-really, pig-natural pond-dish, pig-natural pond-grass, pig-natural pond-ground ", be the effective way that realizes polluting innoxious and resource utilization, but prerequisite is the land resources that enough admittances are arranged.From present actual; utilize the total amount ratio of aforesaid way processing natural pond liquid also little; particularly some areas intensive culture causes culturing natural pond liquid pollution high concentration; generally exceeded and utilized peripheral soil to carry out the ability that nature is dissolved; usually directly be discharged in water body and the surrounding enviroment; formed new problem of environmental pollution, the large-scale cultivation field is the typical case particularly.Therefore, along with the continuous development of production and use of marsh gas chemical industry journey scale, the resource utilization safe handling and the utilization of natural pond liquid receive much concern.
Summary of the invention
The objective of the invention is to, solve natural pond liquid and be applied to agriculture production, pungent odour causes ecological pollution and the low problem of fertilizer efficiency, a kind of removal pungent odour is provided, but and fertilizer efficiency be better than the simple large-scale application of with low cost, embodiment of general natural pond liquid fertilizer, the no natural pond liquid stink that is easy to promote the use of and the high natural pond liquid fertilizer production method of fertilizer efficiency with mixed bacterium.
Technical scheme of the present invention is: a kind of do not have natural pond liquid stink and a high natural pond liquid fertilizer production method of fertilizer efficiency, comprises the steps:
A, fresh natural pond liquid charging: from marsh gas fermentation pool, take out fresh natural pond liquid and pack in the fermentation unit;
B, interpolation waste molasses: waste molasses is added in the liquid of fresh natural pond in proportion;
C, microbe inoculation starter: genus bacillus and photosynthetic bacterium are inoculated in the liquid of fresh natural pond in proportion;
D, shaking table or stir aerobe fermentation: control leavening temperature and fermentation time during fermentation;
E, fermentation back storage: the natural pond liquid fertilizer preservation under normal temperature or refrigerating temperature that will obtain after will fermenting with mixed bacterium.
Further technical scheme is:
The natural pond liquid fertilizer production method that described no natural pond liquid stink and fertilizer efficiency are high, its fresh natural pond liquid is taken from the marsh gas fermentation pool of normal gas producing more than 3～6 months; Fermentation unit is the open type fermenting container, is the cement fermentation vat, or bucket, or fermentor tank.
The amount that the natural pond liquid fertilizer production method that described no natural pond liquid stink and fertilizer efficiency are high, its waste molasses are added in the liquid of fresh natural pond is to add in the liquid of fresh natural pond by mass volume ratio 1%～15%(W/V), and mixes.
The amount that the natural pond liquid fertilizer production method that described no natural pond liquid stink and fertilizer efficiency are high, its genus bacillus and photosynthetic bacterium are inoculated in the liquid of fresh natural pond is distinguished all with 10
4～10
6The inoculum density of individual/mL is inoculated in the liquid of fresh natural pond.
The natural pond liquid fertilizer production method that described no natural pond liquid stink and fertilizer efficiency are high, its shaker fermentation is selected 100r/min～200r/min, select conventional propeller mixer to stir, leavening temperature is controlled to be 20 ℃～37 ℃ of the temperature of bacterial classification suitable growth, and fermentation time is 1 day～6 days.
The natural pond liquid fertilizer production method that described no natural pond liquid stink and fertilizer efficiency are high, the natural pond liquid fertilizer preservation at normal temperatures that obtains having mixed bacterium after the fermentation, its validity period is 6～8 months; Perhaps preservation under 2 ℃～8 ℃ refrigerating temperatures, its validity period is 10～12 months.
The natural pond liquid fertilizer production method that described no natural pond liquid stink and fertilizer efficiency are high, its genus bacillus is selected from Bacillus licheniformis, or subtilis.
Principle of the present invention is: on the one hand by adding in the waste molasses and the pungent odour of natural pond liquid, two kinds of genus bacillus mix aerobe fermentation natural pond liquid simultaneously, transform the stink substance that absorbs in the liquid of natural pond, wherein increase dissolved oxygen in the liquid of natural pond by stirring modes such as (small-sized vibrate for shaking table), change the anaerobic environment of fresh natural pond liquid, thereby remove the pungent odour of natural pond liquid; On the other hand by two kinds of genus bacillus and photosynthetic bacterium mixed fermentation natural pond liquid, macromolecular substance in the liquid of natural pond is degraded to small-molecule substance, helping crop and soil absorbs, in addition, natural pond liquid after the fermentation contains multiple live body probiotics, these probioticss help improving the transformation efficiency of the readily available nutrient of soil after use in the field.
Major advantage of the present invention is as follows:
1) the present invention adopts the mode of mixed fermentation natural pond liquid to produce bio-fertilizer, and is with low cost, has the production cost advantage; 2) embodiment is simple, but large-scale application also is easy to promote the use of; 3) the invention solves natural pond liquid and be used for agriculture production moderate stimulation stink and cause ecological pollution and the low drawback of fertilizer efficiency, really accomplished the resource utilization safe handling and the utilization of natural pond liquid; 4) the natural pond liquid behind mixed fermentation has not only been removed pungent odour, and fertilizer efficiency is better than general natural pond liquid.
