Problems solved by technology

However, during the fermentation and preparation of organic fertilizers, it is still necessary to turn the heap many times to increase the oxygen content in the material and promote the fermentation process, which increases the fermentation cost; at the same time, due to the large number of ammonia-lytic bacteria in the high-temperature fermentation stage, the loss of nitrogen volatilization is relatively large

Embodiment 1

[0050] The embodiment of the present invention provides a method for preparing an organic fertilizer. The preparation method includes: adjusting the water content after compounding sludge and rice husk at a ratio of 3:1, and adjusting the ratio according to the mass percentage of 65% water to obtain organic waste Mixture: Add the microbial composite fermentation agent to the organic waste mixture according to the mass ratio of the microbial composite fermentation agent to the organic waste mixture in a ratio of 1:10000, and use a turning and throwing device to fully mix After stacking, a mixed material heap is formed; the mixed material heap is not turned over and fermented for 15 days to prepare the organic fertilizer of Example 1. Wherein, the effective viable count content of the microbial composite fermentation inoculant is 5.0×10 8 cfu / mL, mainly composed of a concentration of 5.5×10 8 cfu / mL of liquid facultative bacillus and a concentration of 0.5 x 10 8 The cfu / mL li...

Embodiment 2

[0058] The embodiment of the present invention provides a method for preparing organic fertilizer. The preparation method includes: adjusting the water content after compounding pig manure and sawdust in a ratio of 3:1, and adjusting the ratio according to the mass percentage of 60% water to obtain a mixture of organic waste Material; according to the ratio of the mass ratio of the microbial composite fermentation agent to the organic waste mixture of 1:10000, add the microbial composite fermentation agent to the organic waste mixture, and use the turning and throwing equipment to fully mix Pile up to form a mixed material heap; the mixed material heap is not turned over and fermented for 18 days to prepare the organic fertilizer of Example 2. Wherein, the effective viable count content of the microbial composite fermentation inoculant is 5.9×10 8 cfu / mL, mainly composed of a concentration of 6.5×10 8 cfu / mL of liquid facultative bacillus and a concentration of 0.5 x 10 8 Th...

Embodiment 3

[0066] The embodiment of the present invention provides a method for preparing organic fertilizer. The preparation method includes: adjusting the water content after compounding sheep manure and mushroom dregs according to the ratio of 3:1, and adjusting the proportion according to the mass percentage of 56% water to obtain organic waste Mixture: Add the microbial composite fermentation agent to the organic waste mixture according to the ratio of the mass ratio of the microbial composite fermentation agent to the organic waste mixture of 1:11000, and use the turning and throwing equipment to fully mix After stacking, a mixed material heap is formed; the mixed material heap is not turned over and fermented for 12 days to prepare the organic fertilizer of Example 3. Wherein, the effective viable count content of the microbial composite fermentation inoculant is 7.25×10 8 cfu / mL, mainly composed of a concentration of 8.0×10 8 cfu / mL of liquid facultative bacillus and a concentra...

Abstract

The invention provides a preparation method of an organic fertilizer, which comprises the following steps: uniformly mixing organic waste with a microbial compound fermentation inoculant, conducting stacking to form a mixture pile, and carrying out pile-turning-free fermentation treatment on the mixture pile to prepare the organic fertilizer, wherein the effective viable count content of the microbial compound fermentation inoculant is greater than or equal to 5*10<8> cfu/mL, the microbial compound fermentation inoculant comprises liquid facultative anaerobic bacillus and liquid high-temperature nitrogen-fixing bacteria, and the adaptive temperatures of the liquid facultative bacillus and liquid high-temperature nitrogen-fixing bacteria both range from 30 DEG C to 55 DEG C. The preparationmethod of the organic fertilizer provided by the invention has the effects of no need of turning during fermentation, good decomposition effect, reduction of nitrogen volatilization, strong fertilizer retention, short decomposition time, environmental protection, sterilization, insect killing, weeding and the like.

Description

technical field [0001] The invention belongs to the field of fertilizers, and in particular relates to a method for preparing organic fertilizers. Background technique [0002] Organic fertilizers mainly use organic waste as raw materials, are compatible with the soil, are easy to absorb, have good effects, and have relatively little impact on soil properties. Therefore, the research and use of organic fertilizers is a trend in agricultural development. At present, organic fertilizers are mainly prepared by anaerobic fermentation or aerobic fermentation of organic waste. In the existing anaerobic fermentation, the decomposition of organic matter is slow, and the production efficiency of organic fertilizer is low, which generally takes several months, and the equipment required for anaerobic fermentation requires high requirements and large investment. The existing aerobic fermentation has high decomposition efficiency of organic matter and short composting cycle, but the fe...
