Embodiment 1

[0067] Embodiment 1, the making of energy-saving microporous tube such as Figure 5 ;

[0068] 1. Use a PVC pipe with a nominal outer diameter of 50mm and a wall thickness of 2.0mm to take a length of 1.33M;

[0069] 2. Drill a hole with a diameter of 4-5mm on the pipe at an interval of 4-5cm, and the upper and lower adjacent holes should be staggered;

[0070] Invention principle: The oxygen required for fermentation is supplied through the gaps of the fermentation raw material particles. The use of the energy-saving microporous tube can effectively increase the porosity and pore size. Relying on natural ventilation, the energy-saving effect is obvious, and at the same time it is conducive to ventilation and oxygen supply, thus greatly Shorten the fermentation time and reduce turning over.

Embodiment 2

[0071] Embodiment 2, according to image 3 , Figure 4 The energy-saving microporous tube made in Example 1 is placed vertically in the fermenter as shown;

[0072] Fermentation tank according to image 3 , Figure 4 When the spacing shown is constructed, a hole with a depth of 5 cm and a diameter slightly larger than 5 cm is arranged at the bottom of the fermentation tank for placing the energy-saving microporous tube described in Example 1.

Embodiment 3

[0073] Embodiment 3, preparation raw material carries out fermentation

[0074] 1) Prepare the cow dung, chicken manure, zeolite powder, fermenting agent, inorganic nitrogen fertilizer (ammonium sulfate or urea), and crushed crop straw to be fermented.

[0075] 2) One ton of cow dung and chicken dung needs about 3-3.5m 3 , zeolite powder about 30-50kg, fermented bacteria agent, depending on the season and other conditions, according to 3-5kg / m 3 Add, put into a blender and stir evenly; detect the C / N ratio of the mixture;

[0076] 3) Add inorganic nitrogen fertilizer, ammonium sulfate 12-15kg or urea 5.3-8kg or crushed crop stalks to the mixed species to adjust the C / N of the mixture until the C / N is 25%-28%.

[0077] 4) Place the C / N mixture adjusted in 3) in the fermenter arranged in Example 2 for pre-fermentation.

[0078] 5) When the temperature in the pre-fermentation tank reaches 60°C-65°C, turn the fermented product into the adjacent fermentation tank for the second ...

Abstract

The invention discloses a biological organic fertilizer and a production method thereof, and belongs to the field of fertilizers. The biological organic fertilizer contains the following components: more than or equal to 20 million active living bacteria per gram, more than or equal to 45% of organic matters, more than or equal to 5% of total nutrient, less than or equal to 30% of water, and less than or equal to 100 fecal coliform per gram, and has the pH of 5.5-7, wherein the death rate of roundworm ova is more than or equal to 90%, and the validity period is more than or equal to 12 months. The biological organic fertilizer has the effects of a microbial fertilizer and an organic fertilizer, and can change wastes into valuable and protect the environment; and the production method can effectively shorten the production period and reduce the production cost.

Description

technical field [0001] The invention relates to the technical field of fertilizers, in particular to a bio-organic fertilizer produced by energy-saving tubular microporous aeration fermentation and a method thereof. Background technique [0002] Wastes such as livestock and poultry manure and crop stalks have caused serious pollution to the environment. How to make full use of these wastes has become a problem that we must solve. At present, the domestic use of these wastes to produce organic fertilizers has developed rapidly, but most enterprises are faced with problems such as long production cycles or high energy consumption for aerated fermentation, high costs, and the final form of products is mostly powdery, with low granulation rate, etc. problem. Contents of the invention [0003] In order to overcome the deficiencies of the above-mentioned prior art, the object of the present invention is to provide bio-organic fertilizer and method thereof produced by energy-sav...
