Problems solved by technology

[0005] Nowadays, biological composting is generally a high-temperature aerobic composting process of organic materials. One of the current methods is natural composting. The fermentation time of ordinary fertilizers generally takes half a year to a year, or even longer. Not only is the cycle long, but there is also weathering , nutrient loss or incomplete fermentation; the other is produced by professional fertilizer manufacturers using special production equipment, which has problems such as large investment, long fermentation cycle, and ineffective product effects.

Embodiment 1

[0033] 1) Biological A agent is prepared according to the following method:

[0034] (1) Mix 60 parts of rice bran, 15 parts of soybean meal, and 20 parts of wheat bran according to weight parts, then add molasses of 2% of the total mass of the mixture and 5% of compound microbial bacterial agent, mix well, add water to adjust the moisture to 40% , into the fermentation device;

[0035] The molasses is common commercially available molasses with an organic matter content of more than 50%;

[0036] The compound microbial inoculum is a mixture of each single liquid inoculum, in which the volume ratio of Lactobacillus plantarum, Bacillus subtilis, photosynthetic bacteria, yeast and actinomycetes is 3:2:2 :2:1, the strain density in each single liquid bacterial agent is ≥10 8 a / ml;

[0037] (2) Seal the fermentation device and perform anaerobic fermentation at 36°C for 24 hours; then turn it outdoors for 10 days of anaerobic fermentation at room temperature, and test the fermen...

Embodiment 2

[0045] 1) Biological A agent is prepared according to the following method:

[0046](1) Mix 60 parts of rice bran, 20 parts of soybean meal and 20 parts of wheat bran according to the weight parts, then add 3% molasses and 3% compound microbial agent of the total mass of the mixture, mix evenly, add water to adjust the moisture to 42% , into the fermentation device;

[0047] The compound microbial inoculum is a mixture of each single liquid inoculum, in which the volume ratio of Lactobacillus plantarum, Bacillus subtilis, photosynthetic bacteria, yeast and actinomycetes is 5:3:2 :1:1, the strain density in each single liquid bacterial agent is ≥10 8 a / ml;

[0048] (2) Seal the fermentation device and perform anaerobic fermentation at 37°C for 30 hours; then turn it outdoors and perform anaerobic fermentation at room temperature for 9 days, and test the fermented material. After the fermentation is completed, the biological A agent is obtained.

Abstract

The invention relates to the field of biological fertilizers, in particular to a high-quality biological fertilizer and a preparation method thereof. According to the invention, a secondary fermentation method and an indigenous bacteria screening application method are applied innovatively, and a safe, efficient and convenient production method is provided, a microbial environment in which harmonious symbiosis of microbial flora is implemented and indigenous bacteria are dominant flora is obtained, and continuous accumulation of microbial metabolites is promoted. The nutritional value of the biological fertilizer is increased to achieve the following three purposes including, harmlessness, humification and generation of a large number of microorganisms and metabolites of the microorganismssuch as various antibiotics and protein substances.

Description

technical field [0001] The invention relates to the field of biological fertilizers, in particular to a high-quality biological fertilizer and a preparation method thereof. Background technique [0002] Biological fertilizer refers to a kind of special fertilizer that contains a large number of living microorganisms. When this kind of fertilizer is applied to the soil, a large number of living microorganisms can be active under suitable conditions, and some can reproduce in large numbers around the roots of crops to play a role in autogenous nitrogen fixation or Combined with nitrogen fixation; some can also decompose phosphorus and potassium mineral elements for crop absorption or secrete growth hormone to stimulate crop growth. [0003] It can be seen that biological fertilizers do not directly supply the nutrients needed by crops, but provide the nutrients needed by crops and produce hormones to stimulate crop growth through the active activities of a large number of livi...
