Background
At present, the chicken manure is a relatively high-quality organic fertilizer, which contains about 1.63%, 1.54% and 0.085% of pure nitrogen, phosphorus (P2O5) and potassium (K2O), the chicken manure must be decomposed by a decomposing agent before being applied, parasites, eggs and infectious germs in the chicken manure are inactivated and deodorized through a process after being decomposed, the chicken manure organic fertilizer contains medium trace elements, beneficial bioactive bacteria and various enzymes required by plants, the life activities of the microbial bacteria in soil can fix nitrogen in the air, loosen soil and decompose phosphorus and potassium minerals solidified by chemical fertilizers used in the soil for a long time, so that various sufficient nutrient elements are provided for crops, the comprehensive fertilizer efficiency of the chicken manure nutrients is durable, various nutrients required by different growth of the crops can be provided, the physiological functions of the crops can be comprehensively regulated by reasonably using the biological organic fertilizer, the reproductive growth and the nutritional growth can be balanced and stimulated, can make the root system of crops developed, protect flowers and fruits, improve the fruit yield, harvest in advance and improve the sustainable high-yield capability of soil, and the yield is increased by 10 to 15 percent.
However, the animal excrement is liable to generate NH3In the production process of the conventional chicken manure organic fertilizer, odor is easily generated under the action of endogenous and exogenous microorganisms, so that the produced chicken manure organic fertilizer has unpleasant odor. Meanwhile, the existing chicken manure organic fertilizer is not fermented sufficiently, at least two months of fermentation time is needed, and then granulation and packaging production are carried out, so that the production efficiency of the chicken manure organic fertilizer is greatly reduced, the chicken manure can not be fermented and prepared quickly and efficiently, the purpose of saving the production time of the chicken manure organic fertilizer can not be achieved, and great inconvenience is brought to the production of the chicken manure organic fertilizer.
In summary, the problems of the prior art are as follows: (1) the livestock and poultry manure is easy to generate NH3And various unpleasant smells are stimulated, in the process of generating the prior chicken manure organic fertilizer,the odor removal is easy to neglect, so that the produced chicken manure organic fertilizer has unpleasant odor.
(2) The existing chicken manure organic fertilizer has insufficient fermentation, long fermentation time and low production efficiency, and can not realize the fermentation and preparation of chicken manure quickly and efficiently, thereby bringing great inconvenience to the production of the chicken manure organic fertilizer.
(3) The chicken manure is directly used for preparing the organic fertilizer, so that the nutrient content is low, the organic matter content is low, the ripening speed of beneficial microorganisms in soil is low, and the effect of the organic fertilizer cannot be reflected in time.
At present, large organic fertilizer manufacturers taking chicken manure as a main raw material mainly have the following modes for treating the odor of the chicken manure: biological, chemical, bio-chemical and physical methods. The biological method is that a large amount of acidic microorganisms are added in the fermentation process; chemical methods typically add acidic chemical materials such as dilute acids; the biological-chemical method is to comprehensively use biological method and chemical treatment, and the odor is continuously produced along with the fermentation process; the physical method is that large-scale equipment is added, odor is pumped out in various modes and then passes through an acid filter, and the equipment investment is huge. Therefore, the production of odor cannot be inhibited fundamentally, and excessive exogenous equipment and substances are required to be added, so that the production cost of enterprises is increased.
The invention can firstly solve a large amount of foul gas continuously generated in the fermentation process of the chicken manure, and can also reuse a large amount of organic energy in the chicken manure and the furfural residues, wherein the crude protein in the chicken manure is about 30 percent generally, the non-protein nitrogen such as uric acid, ammonia, urea and the like is about 40 percent generally, the crude fiber is about 15 percent generally, and how to effectively utilize the nutrient substances in the furfural residues turns waste into wealth, thereby being the direction of development of pollution-free treatment of the organic wastes of the chicken manure. The furfural residue is utilized to prepare a large amount of organic substances with organic content of more than 80 percent, nitrogen content of 0.4-0.5 percent and phosphorus content (P)2O5) 0.5-0.6%, potassium content of about 1%, can rapidly utilize the nutrient components of the above substances under the combined action of composite microorganism to achieve rapid fermentation and temperature rise, and can reach a temperature of above 70 deg.C for 2-3 days, and can utilize the generated malodorous gasThe adsorption effect of the composite phosphate and the furfural residues is directly converted into available nutritional ingredients in the fermentation body, so that more than 99.9 percent of escherichia coli is effectively killed, the content of ammonia nitrogen is obviously reduced, the fermentation period can be obviously shortened, the germination index is improved, the harmless treatment of chicken manure wastes and organic solid furfural residues wastes is well realized, and the effects of emission reduction and secondary utilization are realized.

Table 2 shows that 10g of the pre-fermentation mixture and the post-fermentation mixture were taken, 90ml of sterilized distilled water was added, diluted and stirred on a magnetic stirrer at normal temperature for 1 hour, centrifuged at 4000rpm for 10 minutes, the filtrate was collected for use, a layer of filter paper was placed in a 90cm dish, sterilized at 130 ℃ by dry heat for 4 hours, 3ml of the above filtrate was added on the filter paper, 20 oilseed rape seeds were placed uniformly, cultured at 25 ℃ in the dark, and the germination rate and total root length were determined after 48 hours, equivalent sterilized distilled water was used as a control, germination index calculation formula was calculated, water addition group was used as a control, GI was 100% (treated group germination rate × seed total root length)/(control group germination rate × seed total root length), each treatment was repeated for 3 times, and SPSS software was used to perform differential analysis on the data, table 2 shows that the change of germination index of the pre-post-fermentation oilseed rape seeds, wherein the germination index of the control group of oilseed rape seeds was (3.45 ± 0.38%), the germination index of the fermented experimental group of oilseed rape seeds was 98.74 ± 5.03, the present invention can sufficiently eliminate the influence of the germination index and the effective components of the furfural and the effective fermentation residues of the present invention can be utilized.
The above description is only for the purpose of illustrating the preferred embodiments of the present invention and is not to be construed as limiting the invention, and any modifications, equivalents and improvements made within the spirit and principle of the present invention are intended to be included within the scope of the present invention.
