Embodiment 1

[0027] A preparation method of a microbial fertilizer that improves the activity of functional bacteria, comprising the steps of:

[0028] Fertilizer decomposing: mix pig manure and wheat straw at a ratio of 2:1, totaling 10kg (sampling test, preliminary estimation: its hydrocarbon organic matter is 69.22wt%, nitrogen content rate is 3.16wt%; its carbon-nitrogen ratio is 30.5:1) Add 5g of Bacillus licheniformis species, stack evenly, control moisture content to about 55%; porosity to 50%; pH to 7.0; temperature to 37°C, ferment for 14 days under ventilated conditions, and turn over in 3 days Pile once, ventilate, and finally get well-rotted organic fertilizer.

[0029] High-temperature sterilization: Air-dry the decomposed organic fertilizer naturally, and then place it in an oven at 80°C to remove most of the miscellaneous bacteria at high temperature.

[0030]Secondary fermentation: After cooling down to normal temperature, take 5kg of air-dried and decomposed organic ferti...

Embodiment 2

[0033] On the basis of Example 1, the concentrated monosodium glutamate waste liquid in the secondary fermentation was replaced with a mixed nutritional supplement of 12g beef extract, 38g peptone and 10g sodium chloride.

[0034] All the other steps are identical with embodiment 1; Wherein, the deviation of control parameters such as above-mentioned humidity, porosity, temperature, pH and embodiment 1 is less than 1.2%.

Embodiment 3

[0036] On the basis of Example 1, the mixed strains in the secondary fermentation were replaced with 10 g of Bacillus subtilis single strains.

[0037] All the other steps are identical with embodiment 1; Wherein, the deviation of control parameters such as above-mentioned humidity, porosity, temperature, pH and embodiment 1 is less than 1.2%.

Abstract

The invention discloses a microbial fertilizer for improving activity of functional microbes and a preparation method of the microbial fertilizer, and belongs to the field of preparation methods of biological fertilizers. The method comprises the following steps: uniformly stacking organic waste, and performing ventilation fermentation to obtain a decomposed organic fertilizer; performing drying naturally, placing the dried material in a drying room, and performing sterilization at a high temperature; adding the functional microbes, a nutrient auxiliary agent and a conditioning agent, performing uniform adsorption, adjusting the humidity, and performing secondary fermentation; and performing granulation on the finished-product microbial fertilizer, performing air drying, and performing packaging. According to the method provided by the invention, after the sterilization operation is completed, the secondary fermentation is performed, inoculation is performed by using the functional microbes, so that a quantity of impurity microbes is reduced, and the dominant position of the functional microbes is improved; the nutrient auxiliary agent is added into the organic fertilizer, so thatthe survival activity of the microorganisms is improved, improvement of activity of the microorganisms is facilitated, respiratory metabolism to release heat of the microorganisms is promoted, and decomposition of the organic fertilizer is slowed down; and the method solves the problem that functional microbes of a current microbial fertilizer have a poorer survival effect and the microbial fertilizer has a shorter shelf life.

Description

technical field [0001] The invention belongs to the field of production methods of biological fertilizers, in particular to a microbial fertilizer for improving the activity of functional bacteria and a production method thereof. Background technique [0002] Chemical fertilizers and pesticides are the main material basis of my country's agricultural production, ensuring the yield and quality of food. However, the long-term and large-scale use of the two has also led to low fertilizer utilization rates for crops, decline in the quality of agricultural products, serious agricultural pollution, and water pollution. Eutrophication and a series of ecological environment and food safety issues. Therefore, under the premise of ensuring food supply and safety, how to change the excessive dependence on chemical fertilizers and pesticides and reduce the negative impact of the two is a realistic problem that needs to be solved urgently for the sustainable development of my country's ag...
