Abstract

The invention provides a method for preparing an organic fertilizer by mixing pig manure with sawdust. According to the method, as for a raw material and auxiliary materials, the raw material is 100kg of pig manure and the auxiliary materials are 50kg of sawdust and 50kg of waste materials such as grain bran powder; the C/N ratio of the raw material and the auxiliary materials is controlled to be 23-28 and the water content of the pig manure after proportioning is controlled to be 52-68%; as for pile dimensions, during natural ventilation, the height is 1.0-1.5m, the width is 1.5-3.0m and the length is random; and as for temperature variation, the complete composting process is formed by a low-temperature stage, a medium-temperature stage, a high-temperature stage and a cooling stage, the compost temperature is generally 50-60 DEG C and the highest compost temperature can reach 70-80 DEG C, the process in which the temperature gradually rises is a compost harmless treatment process, and the compost is maintained for ten days at high temperature (45-65 DEG C) and pathogenic bacteria, eggs, grass seeds and the like can be killed. 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 mixed wood chip of a kind of pig manure prepares the method for fertilizer

 

Technical field:

The present invention relates to the Production of manure technical field, particularly the mixed wood chip of a kind of pig manure prepares the method for fertilizer.

 

Background technology:

Fertilizer, mainly contain nitrogen, phosphorus, potassium element, replenish the nutrition of running off for earth, 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, the utilization ratio fertilizer that improves fertilizer contains that nutrient is many but relative content is low, discharge slowly, and chemical fertilizer unit nutrient content is high, and composition is few, discharges fast.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, the mixed wood chip of a kind of pig manure that is conducive to plant growth prepares the method for fertilizer.

 

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, the mixed wood chip of a kind of pig manure that is conducive to plant growth prepares the method for fertilizer.

 

To achieve these goals, the invention provides the method that the mixed wood chip of a kind of pig manure prepares fertilizer, it is characterized in that, comprise the steps:

(1) raw material and auxiliary material

Raw material: 100 kilograms of pig manures.

Auxiliary material: 50 kilograms of the rejected materials such as 50 kilograms of wood chips, husk powder;

(2) ratio requirement

Supplementary material: the C/N ratio is controlled at 23-28.

Water content: the water content of pig manure is controlled at 52%-68% after the proportioning;

(3) the high size of heap: during natural ventilation, height 1.0-1.5 rice, wide 1.5-3.0 rice, length is any.

(4) temperature variation: complete composting process is comprised of low temperature, middle temperature, high temperature and cooling four-stage.Compost temperature is generally at 50-60 ℃, Gao Shikeda 70-80 ℃.Temperature is the existing process that raises gradually from low to high, is the treating processes of compost hazard-free.Compost was kept 10 days at high temperature (45-65 ℃), and pathogenic bacteria, worm's ovum, grass-seed etc. all can be killed;

(5), turning: compost temperature rises to more than 60 degree, keeps beginning turning after 48 hours, (but when temperature is spent above 70, immediately turning), the uniform and complete of being sure to during turning is ploughed under the heap middle and upper part with the low layer material as far as possible, in order to fully become thoroughly decomposed, determine the turning number of times depending on the material degree of becoming thoroughly decomposed.

 

Technique of the present invention is simple, and is easy to make, suppresses disease and pest, improves edatope and potential of hydrogen, is conducive to plant growth.
