Abstract

The invention provides a method for preparing an organic fertilizer by fermenting poultry excrement and crop straws in a mixed manner. The method comprises the following steps of: A. grinding the straws until the grain sizes are 200-250 meshes; B. stirring the poultry excrement and the straws, adding lime powder to adjust the pH value to 7-8, then adding probiotics and stirring the materials uniformly; C. after turning, keeping the moisture to be 65-70%; and D. carrying out granulating, drying and packaging after fermentation. 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 manufacture method of poultry dung and crop material mixed fermentation fertilizer

 

Technical field:

The present invention relates to the Production of manure technical field, particularly the manufacture method of a kind of poultry dung and crop material mixed 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 manufacture method of a kind of poultry dung and the crop material mixed 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 manufacture method of a kind of poultry dung and the crop material mixed fermentation fertilizer of plant growth.

To achieve these goals, the invention provides the manufacture method of a kind of poultry dung and crop material mixed fermentation fertilizer, wherein, comprise the steps:

A, crushing straw be to the 200-250 order,

B, poultry dung and stalk are stirred, adding lime powder, to adjust to potential of hydrogen be 7-8, adds probiotic bacterium again, stirs;

After C, process are turned over throwing, make moisture remain on 65%-70%.

Carry out granulation after D, the fermentation, oven dry, encapsulation.

 

Manufacture method of the present invention, each component adopts following proportioning, disposes following raw material according to weight unit

Poultry dung 20-30 part

Crop material 40-50 part

Lime powder 2-6 part

Probiotic bacterium 1.5-15 part.

Perhaps, wherein, dispose following raw material according to weight unit

Poultry dung 20-25 part

Crop material 40-45 part

Lime powder 2-4 part

Probiotic bacterium 1.5-10 part.

Perhaps, wherein, dispose following raw material according to weight unit

Poultry dung 25-30 part

Crop material 45-50 part

Lime powder 3-6 part

Probiotic bacterium 6-15 part.

Perhaps, wherein, dispose following raw material according to weight unit

Poultry dung 22-28 part

Crop material 32-38 part

Lime powder 3-5 part

Probiotic bacterium 7-12 part.

Described poultry dung is chicken manure, and described crop material is rice straw or maize straw, and described probiotic bacterium is the EM bacterium.

 

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 manufacture method of poultry dung of the present invention and crop material mixed fermentation fertilizer wherein, comprises the steps:

A, crushing straw be to the 200-250 order,

B, poultry dung and stalk are stirred, adding lime powder, to adjust to potential of hydrogen be 7-8, adds probiotic bacterium again, stirs;

After C, process are turned over throwing, make moisture remain on 65%-70%.

Carry out granulation after D, the fermentation, oven dry, encapsulation.

 

Example 1 poultry dung and crop material mixed fermentation fertilizer, wherein, dispose following raw material according to weight unit:

30 parts of poultry dungs

50 parts of crop materials

6 parts of lime powders

15 parts of probiotic bacteriums.

 

Example 2 poultry dungs and crop material mixed fermentation fertilizer, wherein, dispose following raw material according to weight unit:

20 parts of poultry dungs

40 parts of crop materials

2 parts of lime powders

1.5 parts of probiotic bacteriums.

 

Example 3 poultry dungs and crop material mixed fermentation fertilizer, wherein, dispose following raw material according to weight unit:

25 parts of poultry dungs

45 parts of crop materials
