Problems solved by technology

[0004] Biological organic bacterial fertilizer is made by fermenting livestock and poultry manure and adding beneficial microorganisms. However, the existing biological organic bacterial fertilizer takes a long time to ferment, has a single strain, and is easy to cause the death of aerobic microorganisms, which cannot effectively ferment the bacterial fertilizer. Reproduction, thus affecting the effect of bacterial fertilizer

preparation example Construction

[0029] The present invention provides the preparation method of compound bio-organic bacterial fertilizer described in above-mentioned technical scheme, comprises the following steps:

[0030] The straw is crushed and mixed with livestock and poultry manure to obtain primary organic fertilizer;

[0031] After mixing the primary organic fertilizer with the fermented liquid, carry out aerobic fermentation to obtain pure organic fertilizer;

[0032] After the pure organic fertilizer is mixed with living biological bacteria, fermentation treatment is carried out to obtain compound biological organic bacterial fertilizer.

[0033] In the invention, the straw is pulverized and mixed with livestock and poultry manure to obtain primary organic fertilizer. In the present invention, the mixing method is preferably stirring. The present invention does not have any special limitation on the specific method of pulverization, and the methods known to those skilled in the art can be used. ...

Embodiment 1

[0039] Material preparation: 100 parts of pig manure (21.19kg), 10 parts of rice straw (2.12kg), 5 parts of fermentation broth (1.06kg), and 3 parts of live microorganisms (625g). Among them, the biological living bacteria are mainly photosynthetic bacteria and Bacillus subtilis, and the mass ratio is 1:2.

[0040] Preparation process:

[0041] After crushing the harvested rice stalks, mix them with pig manure, and stir them several times to get the primary organic fertilizer;

[0042] After spraying the fermentation liquid on the above-mentioned primary organic fertilizer, turn it over and mix it, and put the mixed material in the compost area for aerobic fermentation; when the temperature rises above 60°C, turn it over and blast it every 3 days; good After 14 days of oxygen fermentation, pure organic fertilizer is obtained;

[0043] When the temperature is cooled to 35°C, live biological bacteria are added to the pure organic fertilizer and fermented for another 7 days to ob...

Abstract

The invention relates to the field of fertilizers, and concretely relates to a composite biological organic bacterial fertilizer, and a preparation method and application thereof. The composite biological organic bacterial fertilizer is prepared from, by mass, 100-125 parts of livestock and poultry manure, 10-15 parts of straw, 5-8 parts of fermentation liquor and 3-5 parts of biological viable bacteria. The bacterial fertilizer provided by the invention takes livestock and poultry manure as a main raw material and straw as an auxiliary material, and has the advantages of short fermentation time, diverse strains and difficulty in causing death of aerobic microorganisms.

Description

technical field [0001] The invention relates to the field of fertilizers, in particular to a compound biological organic bacterial fertilizer and its preparation method and application. Background technique [0002] In the past, the long-term excessive application of chemical fertilizers in farmland soil was the main reason for the loss of organic matter in farmland soil, soil compaction and salinization, the imbalance of soil microbial population structure, and the aggravation of agricultural non-point source pollution. Livestock and poultry manure contains a large amount of organic matter and nutrients such as nitrogen, phosphorus, and potassium, and is a cheap source of organic fertilizer. The application of organic fertilizers can increase soil organic carbon sources, promote the restoration of soil biodiversity, and improve soil physical and chemical properties and microbial activity. However, the traditional organic fertilizer composted from livestock and poultry manu...
