Abstract

The invention provides a method for preparing an organic fertilizer by fermenting pig manure. The method comprises the following steps that: A. 1.6 tons of pig manure with moisture controlled at 40% taken as the raw material, 5kg of probiotic liquid and 2-3kg of corn meal are mixed, stirred uniformly and crushed; B. 8-10kg of sawdust and 50-75kg of vinasse are mixed; C. the mixtures A and B are piled up to form strip-type piles with width being 2m, height being 0.5m and unlimited length, the strip-type piles are covered with old sack pieces or straw mats, the temperatures of the piles are raised to about 50 DEG C within 24 hours, and the temperatures of the piles can be raised above 60 DEG C and even 70 DEG C within 48 hours; and D. the raw materials in the piles can be completely decomposed generally in 5-7 days in spring, summer and autumn, the stinks disappear and all the pathogenic bacteria, eggs and grass seeds in the raw materials are killed. The method has the advantages that the organic fertilizer has simple process, is convenient to prepare, controls diseases and pests, improves the soil environment and pH value and is beneficial to crop growth.

Description

The preparation method of pig manure fermentation fertilizer

 

Technical field:

The present invention relates to the Production of manure technical field, particularly a kind of preparation method of pig manure fermentation fertilizer.

 

Background technology:

Fertilizer, mainly contain nitrogen, phosphorus, potassium element, for earth replenishes the nutrition of running off, thereby increase the output of crop, still, frequent and single use along with chemical fertilizer application, bring disadvantageous effect to edatope, soil is under the condition that lacks sufficient organic matter, and soil aggregate is difficult to form, adhesive power between the soil particle weakens, and has lowered the water retention capacity of soil now.When earth can't keep the moisture of abundance, even the chemical fertilizer quality is high, also is not easy to chemical fertilizer and under favourable condition, discharges nutrient.Fertilizer has appearred in the problem that causes for solving the single chemical fertilizer of life-time service on the market, not only contain the essential macroelement of plant, trace element in the fertilizer, also contains abundant organic nutrient, and fertilizer is the most comprehensive fertilizer.The effect of fertilizer in agriculture production is mainly manifested in the following aspects: after 1, improvement soil, culture fertility organic fertilizer are manured into soil, organic mass-energy is improved soil physical chemistry situation and biological nature effectively, vegetable soil, strengthen fertilizer supply and preservation ability and the surge capability of soil, for good edaphic condition is created in the growth of crop.2, increase output, raising quality organic fertilizer contain abundant organism and various nutritive element, for farm crop provide nutrition.Behind the fertilizer decomposition, for soil microbial activity provides energy and nutriment, promote microbial activities, accelerate organic matter decomposition, the active substance of generation etc. can promote the growth of crop and improve the quality of agricultural-food.3, it is many but relative content is low that the utilization ratio fertilizer that improves fertilizer contains nutrient, discharge slowly, and chemical fertilizer unit nutrient content is high, and composition is few, discharges soon.Both use by reasonable coordination, mutually replenish, and the organic acid that organic matter decomposition produces can also promote the dissolving of mineral nutrient in soil and the chemical fertilizer.Fertilizer and chemical fertilizer are mutually promoted, and are conducive to Crop, improve the utilization ratio of fertilizer.Though fertilizer has above-mentioned advantage, still, present fertilizer, prescription and manufacture craft on the market is too complicated, and the kind and the method that add bacterial classification cause high cost, have increased peasant's burden.

In view of above-mentioned technological deficiency, simple, easy to make in the urgent need to a kind of technique occurring, suppress disease and pest, improve edatope and potential of hydrogen, be conducive to the preparation method of a kind of pig manure fermentation fertilizer of plant growth.

 

Summary of the invention:

The object of the invention is to overcome the shortcoming that exists in the prior art, provide a kind of technique simple, easy to make, suppress disease and pest, improve edatope and potential of hydrogen, be conducive to the preparation method of a kind of pig manure fermentation fertilizer of plant growth.

To achieve these goals, the invention provides a kind of preparation method of pig manure fermentation fertilizer, wherein, comprise the steps:

A, do raw material with pig manure, moisture controlled is 40%, and 1.6 tons of weight are as raw material, 5 kilograms of probiotic bacterium liquid, 2-3 kilogram Semen Maydis powder mix mix all broken,

B, wood chip 8-10 kilogram, vinasse 50-75 kilogram mixes;

C, A and B mixture are piled the bar stack that wide 2 meters, high 0.5 meter, length are not limit, build with Used Gunny Bag sheet or straw screen or mat, in 24 hours, about heap temperature rise to 50 ℃; In 48 hours, the heap temperature can rise to more than 60 ℃, even up to more than 70 ℃;

The heap Raw is all become thoroughly decomposed, and stench disappears, and the pathogeny bacterium in the raw material, worm's ovum, grass-seed all kill.

 

The invention has the advantages that technique of the present invention is simple, and is easy to make, suppress disease and pest, improve edatope and potential of hydrogen, increase fertilizer nitrogen content, be conducive to crop growing state.

 

Embodiment:

The preparation method of pig manure fermentation fertilizer of the present invention wherein, comprises the steps:

A, do raw material with pig manure, moisture controlled is 40%, and 1.6 tons of weight are as raw material, 5 kilograms of probiotic bacterium liquid, 2-3 kilogram Semen Maydis powder mix mix all broken,

B, wood chip 8-10 kilogram, vinasse 50-75 kilogram mixes;

C, A and B mixture are piled the bar stack that wide 2 meters, high 0.5 meter, length are not limit, build with Used Gunny Bag sheet or straw screen or mat, in 24 hours, about heap temperature rise to 50 ℃; In 48 hours, the heap temperature can rise to more than 60 ℃, even up to more than 70 ℃;

The heap Raw is all become thoroughly decomposed, and stench disappears, and the pathogeny bacterium in the raw material, worm's ovum, grass-seed all kill.
