Abstract
The invention discloses a method for preparing an organic fertilizer by fermenting cow dung compost. According to the method, two times of composting fermentation are adopted and a composting promoter is added, so that the fermentation speed and the composting degree can be quickly increased; meanwhile, polyacrylamide, bentonite, cocoanut active charcoal and the like are added to reduce the moisture in cow dung and achieve the effect of deodorizing; sodium bicarbonate and triple superphosphate are added to generate carbon dioxide which can expand the cow dung, so that the permeability is increased; the early-stage fermentation temperature of the cow dung can be increased by the heat released from reaction, so that the activity of natural fermentation bacteria agents in the cow dung is improved; meanwhile, when the heat generated by the cow dung after a period time of composting is overhigh, the polyacrylamide absorbs the moisture in the cow dung to achieve the effect of reducing the temperature and to reduce turning times; after the fermentation is completed, the organic fertilizer prepared by drying and dewatering is high in fertilizer efficiency, durable and efficient, has the effects of retaining water, sterilizing and improving soil, and can promote the rapid growth of crops, thus improving the yield and the quality of the crops.
Description
Technical field
The present invention relates to a kind of method that cow dung compost fermentation prepares fertilizer, belong to technical field of fertilizers.
Background technology
Along with developing rapidly of China's livestock industry, the livestock and poultry feces pollution on the environment is more and more serious.Harmless treatment is mainly carried out by modes such as anaerobically fermenting and compost fermentations in general cattle farm, because anaerobically fermenting is subject to the capacity limit of device, is not suitable for larger plant and adopts.Due to moisture content in cow dung, more than 80%, the active temperature that this has just affected spontaneous fermentation bacterium in the ventilation property of cow dung and cow dung, make the cattle manure cycle stretch-out.During domestic current cow dung compost fermentation, mostly adopt methods such as adding straw, rice husk absorb moisture and increase ventilation property, it is not thorough that this method rice husk, straw become thoroughly decomposed, and imposes on farmland and easily cause secondary to become thoroughly decomposed to burn the seedling phenomenon.
Summary of the invention
The object of the present invention is to provide a kind of cow dung compost fermentation to prepare the method for fertilizer, adopt the mode of fermenting twice, solved the material mixed fermentations such as cow dung and stalk slowly, the incomplete shortcoming of fermenting, have that fermentation maturity is fast, odorless, free from environmental pollution, cost is low, simple, convenient transportation, be easy to the advantage such as popularization.
The technical solution used in the present invention is as follows:
A kind of cow dung compost fermentation prepares the method for fertilizer, comprises the following steps:
(1) with 1000 parts of cow dung weighing scales, getting 50-80 part plant straw powder, 40-60 part paulownia sawdust, 20-30 part egg-shell meal, 10-15 part furfural dregs, 8-12 part peanut hull meal, 10-15 part volcanic ash, 5-10 part cocoanut active charcoal, 3-5 part composting promoter adds in cow dung, 3-5% by the compound amount adds 200 times of EM probiotic bacterium diluents again, stir, moisture controlled is at 50-60%, compost fermentation 5-8 days at 50-65 ℃ of temperature;
(2) after initial fermentation finishes, compost is carried out to complete stirring, add again the wilkinite of compost weight 4-6%, the double superhosphate of 3-4%, the sodium bicarbonate of 2-3%, the polyacrylamide of 1-2%, the bamboo charcoal powder of 2-3%, stir, continue to keep the condition of initial fermentation constant, once, secondary fermentation in 10-15 days completes in every 5-6 days turning;
(3) fermented product obtained in step (2) is dried to water content be 30-40%, pulverized the 60-80 mesh sieve, add the plant ash of 3-5%, the Oleum Bulbus Allii of 1-2%, the eucalyptus oil of 1-2%, the water glass of 5-8%, the bitter Folium Artemisiae Argyi powder of 1-2%, the chinaberry leaf powder of 1-2%, the camphor powder of 0.5-1%, stir, granulation, dry, be organic fertilizer.
Described composting promoter is made by following methods: the weight ratio by weight 2-3:1 is got peat soil and loess, after mixing, add appropriate water making beating to make the slurries that concentration is 40-50%, add the wood vinegar of 5-10%, the humic acid of 3-6%, the waste molasses of 2-3%, the methane waste liquor of 3-4%, the cellulase of 0.5-1%, the citric acid of 1-2%, high-speed stirring 10-15min gets final product again.
Beneficial effect of the present invention:
The present invention adopts twice compost fermentation and adds composting promoter, can the high fermenting speed of Quick and the degree of becoming thoroughly decomposed, add polyacrylamide, wilkinite, cocoanut active charcoal etc. to reduce moisture and deodorizing effect between cow dung simultaneously, add sodium bicarbonate and double superhosphate generate carbonic acid gas can bulk cow dung, increase ventilation property, exothermic heat of reaction can increase cow dung prior fermentation temperature, and spontaneous fermentation microbial inoculum activity in cow dung is increased; Simultaneously, when cow dung was become thoroughly decomposed and produced heat when too high through for some time, polyacrylamide absorbs moisture in cow dung can play the reduction temperature action again, reduce the turning number of times, the fertilizer fertilizer efficiency made by drying and dewatering of having fermented is good, and persistent high efficiency has water conservation sterilization, the effect of improvement soil, can promote the farm crop Fast Growth, improve the yield and quality of farm crop.
Embodiment
A kind of cow dung compost fermentation prepares the method for fertilizer, comprises the following steps:
(1) with 1000 parts of cow dung weighing scales, getting 60 parts of plant straw powders, 50 parts of paulownia sawdusts, 25 parts of egg-shell meals, 15 parts of furfural dregs, 10 parts of peanut hull meals, 10 parts of volcanic ash, 6 parts of cocoanut active charcoals, 4 parts of composting promoters adds in cow dung, add again 200 times of EM probiotic bacterium diluents by 4% of compound amount, stir, moisture controlled is at 50-60%, and at 60 ℃ of temperature, compost fermentation is 7 days;
(2) after initial fermentation finishes, compost is carried out to complete stirring, add again the wilkinite of compost weight 5%, 3% double superhosphate, 2% sodium bicarbonate, 1.5% polyacrylamide, 2% bamboo charcoal powder, stir, continue to keep the condition of initial fermentation constant, once, secondary fermentation in 10 days completes in turning in every 5 days;
(3) fermented product obtained in step (2) is dried to water content be 6%, pulverized 80 mesh sieves, add 4% plant ash, 1.5% Oleum Bulbus Allii, 1% eucalyptus oil, 6% water glass, 1% bitter Folium Artemisiae Argyi powder, 2% chinaberry leaf powder, 0.6% camphor powder, stir, granulation, dry, be organic fertilizer.
