Abstract
The invention relates to a method for preparing an organic fertilizer by using microbial fermentation fungus dregs subjected to innocent treatment. The method comprises the following steps of: (1) adding quick lime in microbial fermentation fungus dregs, and adjusting the pH value; (2) adding silkworm excrements, uniformly mixing materials, and then, naturally stacking for fermentation; and (3) granulating and drying. By using the method, the pollution problem of a microbial fermentation enterprise is solved; and the microbial fermentation fungus dregs and the silkworm excrements used as byproducts generated by the local sericulture are treated simultaneously, thus the organic matter content is greatly increased, and the fertilizer efficiency is increased. The method is simple and convenient to operate, smaller in investment, high in yield and capable of turning wastes into things of value; and the prepared organic fertilizer is an efficient and environment-friendly fertilizer, and the technical index of the organic fertilizer conforms to the provision of the industrial standard NY525-2012 organic fertilizer of the ministry of agriculture.
Description
Technical field
The invention belongs to microbial fermentation bacterium slag for comprehensive and utilize technical field, the bacterium slag that particularly relates to a kind of microbial fermentation generation is made the method for fertilizer after harmless treatment.
Background technology
Improving constantly along with people's living standard in recent years; people are to the enhancing of environmental protection consciousness; and the Chinese government has strengthened the environmental protection law enforcement dynamics, since 1997 to the attention of ecotope; country's environmental pollution is administered further and is paid attention to; fermentation producer byproduct emission is controlled, from the Pollution abatement angle, supervised microbial fermentation enterprise to change traditional thinking; turn waste into wealth, turn harm into good.Microbial fermentation bacterium slag is the remaining solid thing after the agricultural chemicals leavened prod extracts, its main component is: mycelium, the substratum that has not utilized---starch, ground rice, analysis for soybean powder, peanut powder etc., and the meta-bolites that produces in the fermenting process, the zymophyte slag is rich in large amount of organic matter, and contains nutritive elements such as a spot of nitrogen, phosphorus, potassium, is fit to very much make microbial organic fertilizer.
Fertilizer has very strong effect.The chemical fertilizer nutritive element has only one or more, and chemical fertilizer can make the crop microbial population single, and disease and pest easily takes place, and uses too much easily to cause quality of agricultural product inferior.With traditional inorganic fertilizer ratio, fertilizer can promote the utilization of chemical fertilizer, improve chemical fertilizer utilization ratio, and can improve the soil, culture fertility, vegetable soil, fertilizer-preserving ability and the buffering ability of enhancing soil are that good edaphic condition is created in the growth of crop, organic fertilizer contains abundant organism and various nutritive element, for farm crop provide nutrition, for the soil microorganisms activity provides energy and nutriment, promote microbial activities, accelerate organic matter decomposition, can improve the crop rhizosphere micropopulation, improve the resistant to diseases and insects of plant, the active substance of generation etc. can promote the growth of crop and improve the quality of agricultural-food.
As microbial fermentation pesticide producing enterprise, the problem that solves the microbial fermentation bacterium slag that produces in the production process is imperative.
Summary of the invention
The purpose of this invention is to provide a kind of bacterium slag that is produced by microbial fermentation and make the method for organic fertilizer, solve the pollution problem of microbial fermentation enterprise, turn waste into wealth.
The technical scheme that technical solution problem of the present invention is taked is, a kind of microbial fermentation bacterium dregs innocent is handled the method that fertilizer is made in the back, and it may further comprise the steps:
⑴ add certain amount of calcined lime in microbial fermentation bacterium slag, with pH regulator to 5.5 ~ 8.5;
⑵ add silkworm excrement by certain mass ratio in regulating the microbial fermentation bacterium slag of pH, mix the back and stack fermentation naturally, and fermentation time was controlled at 7 ~ 20 days;
⑶ microbial fermentation bacterium slag and the silkworm excrement mixture after stacking fermentation naturally carries out granulation and oven dry, massfraction≤30% of control moisture.
As a kind of preferred, by quality ratio, microbial fermentation bacterium slag: silkworm excrement is 1: 0.4 ~ 0.6.
Because microbial fermentation bacterium slag contains certain moisture, acidity is stronger, and especially for microbial fermentation pesticide producing enterprise, it is residual etc. that its microbial fermentation bacterium slag contains trace pesticide, so must just can make fertilizer by after the harmless treatment.The present invention adds certain amount of calcined lime and is adjusted to suitable pH in microbial fermentation bacterium slag, destroy pesticide residue simultaneously, and the add-on of unslaked lime is as the criterion with pH regulator to 5.5 ~ 8.5 with microbial fermentation bacterium slag; Then microbial fermentation bacterium slag and silkworm excrement are mixed by 1: 0.4 ~ 0.6 mass ratio, and stack the fermentation of becoming thoroughly decomposed under field conditions (factors), stacking the time of fermentation decides on climate condition, usually summer time solar term temperature is higher, the suitable weak point of fermentation time a bit, the low fermentation time of time in winter temperature should be grown a bit, pass through fermentative degradation, reduce pesticide residue, further remove hazardous and noxious substances wherein, slag is degraded to monose, disaccharide etc. are as carbon source, protein degradation is that peptide class and amino acid are as nitrogenous source, produce and to comprise multiple organic acid in a large number, peptide class and comprise nitrogen, phosphorus, potassium is convenient to crop and is absorbed at interior abundant nutritive element; Because silkworm excrement is a kind of movement that is rich in large amount of organic matter, add silkworm excrement and can serve as carrier on the one hand, can increase organic composition again on the other hand, improve organic content, improved the fertilizer efficiency of fertilizer.
In the production process of the present invention, need carry out the detection of poisonous residue for microbial fermentation bacterium slag and the silkworm excrement mixture of stacking fermentation through nature, detect and carry out granulation and oven dry again after qualified, the finished product also need to test according to the standard of fertilizer, what conformance with standard required is qualified product, packs again.
The present invention is easy and simple to handle, drops into lessly, and productive rate is big, and turns waste into wealth, and the fertilizer that makes is a kind of green fertilizer of high-efficiency environment friendly.And the present invention is that the silkworm movement---silkworm excrement is handled with already producing by product when cutworm, has improved organic content greatly, has improved fertilizer efficiency.The technical indicator of the fertilizer that makes meets the regulation of The Ministry of Agriculture of the People's Republic of China, MOA's industry standard " NY525-2012 organic fertilizer ".
