Description

Technical Field

[0001] This invention relates to the field of organic fertilizer fermentation, and in particular to a special organic fertilizer for passion fruit made from chicken manure and its preparation method. Background Technology

[0002] How to treat livestock and poultry manure without causing environmental pollution is a problem facing the livestock industry. The traditional method of treating livestock and poultry manure is mainly to use it as organic fertilizer for crop cultivation. Compared to inorganic fertilizers, organic fertilizer is currently the preferred choice for balanced and scientific fertilization. Soil that has used chemical fertilizers for many years is prone to compaction, poor granular structure, severe soil erosion, or excessive potassium content. Using organic fertilizer can effectively alleviate these problems. The process of producing organic fertilizer from livestock and poultry manure can effectively resolve the manure problems generated by the livestock industry and ensure an environmentally friendly and healthy development model for the livestock industry.

[0003] Organic fertilizer, processed from livestock manure, has wide applications. It is an important fertilizer in agricultural production, increasing crop yield and quality while preventing soil compaction and acidification. Currently, commonly used organic fertilizers as base fertilizers are oilseed cake and livestock manure. However, unfermented oilseed cake and livestock manure pose safety hazards, potentially causing root burn or introducing pathogens. Existing organic fertilizers also generally suffer from low nutrient content, poor quality, and strong odors, leading to a poor experience for workers handling manure and using the fertilizer due to the strong smell.

[0004] Therefore, in the process of producing organic fertilizer from livestock and poultry manure, how to improve the quality and nutrient content of organic fertilizer to meet the nutritional needs of plants, while also removing unpleasant odors to the greatest extent, is an urgent problem to be solved. Summary of the Invention

[0005] The purpose of this invention is to provide a special organic fertilizer for passion fruit made from chicken manure and its preparation method, so as to solve the problems existing in the prior art. The special organic fertilizer for passion fruit made from chicken manure provided by this invention can better meet the nutritional needs of plants, improve the soil conditions, and is environmentally friendly, odorless, and easy to operate manually.

[0006] To achieve the above objectives, the present invention provides the following solution:

[0007] This invention provides a method for preparing chicken manure-based organic fertilizer specifically for passion fruit, comprising the following steps:

[0008] Add a deodorizing agent to chicken manure for fermentation and deodorization to obtain chicken manure water;

[0009] The fermentation bedding material is spread flat on the ground, and the chicken manure water is sprayed onto the fermentation bedding material every day. At the same time, fermentation bacteria are sprinkled in for aeration and oxygen supply for fermentation.

[0010] The deodorizing agent includes nitrifying bacteria, Bacillus subtilis and Pseudomonas, and the ratio of the number of viable bacteria of the nitrifying bacteria, Bacillus subtilis and Pseudomonas is (2-3):(1-2):(1-4);

[0011] The fermentation agent includes Bacillus licheniformis, Bacillus subtilis, Saccharomyces cerevisiae, lactic acid bacteria and Aspergillus niger, and the ratio of the number of viable bacteria of Bacillus licheniformis, Bacillus subtilis, Saccharomyces cerevisiae, lactic acid bacteria and Aspergillus niger is (2-3):(2-3):(3-5):(2-4):(1-2);

[0012] The fermentation bedding material, by weight, comprises the following mixture of raw materials: 10-20 parts feed dust, 10-20 parts waste paper scraps, 10-20 parts tea dust, 10-15 parts passion fruit shells, and 5-10 parts eggshells.

[0013] Further, the deodorizing agent is prepared by: preparing a compound bacterial solution 1 by mixing the nitrifying bacteria, the Bacillus subtilis and the Pseudomonas aeruginosa, and adding lysozyme to the compound bacterial solution 1 to prepare the deodorizing agent; the mass ratio of the compound bacterial solution 1 to the lysozyme is (2-9):(1-4).

[0014] Furthermore, during fermentation and deodorization, the mass ratio of the deodorizing agent to the chicken manure is (0.5-1):1000.

[0015] Furthermore, the fermentation and deodorization process takes 5 days, during which the mixture is stirred twice a day for 30 minutes each time.

[0016] Further, the fermentation agent is prepared by: preparing a compound bacterial solution 2 by mixing the Bacillus licheniformis, Bacillus subtilis, Saccharomyces cerevisiae, lactic acid bacteria and Aspergillus niger; adding cellulase and lipase to the compound bacterial solution 2 to prepare the fermentation agent; the mass ratio of the compound bacterial solution 2 to the cellulase and the lipase is (10-17):(1-2):(1-2).

[0017] Furthermore, the spray volume of the chicken manure water is 1 / 10 of the volume of the bedding material.

[0018] Furthermore, the amount of fermentation agent added is 0.4% of the mass of the bedding material.

[0019] Furthermore, the aeration and oxygen supply fermentation time is 45–60 days.

[0020] Furthermore, the moisture content of the chicken manure before the addition of the deodorizing agent is 70-80%.

[0021] The present invention also provides a special organic fertilizer for passion fruit made from chicken manure obtained by the above preparation method.

[0022] The present invention discloses the following technical effects:

[0023] This invention utilizes waste paper scraps, passion fruit shells, and discarded eggshells in organic fertilizer fermentation bedding, optimizing resource allocation and turning waste into treasure. The cellulose in waste paper scraps and passion fruit shells can be converted into sugar, providing ample carbon to the soil. The pulverized waste paper scraps are inexpensive and play a role in loosening, aerating, and absorbing harmful substances during chicken manure fermentation. Tea dust is rich in organic matter and has deodorizing, odor-absorbing, and water-absorbing properties. Eggshells significantly increase the amount of calcium and other trace organic elements in the organic fertilizer. Simultaneously, this invention employs a segmented fermentation process. First, a deodorizing agent is added to decompose odorous substances in the chicken manure, followed by a fermentation agent to produce beneficial nutrients. Both the deodorizing and fermentation agents are optimized formulations based on the raw materials and do not contain pathogens. They have a regulating and restorative effect on the soil and contain various enzymes in addition to microbial strains. Among them, lysozyme can kill pathogens; cellulase and lipase can rapidly decompose proteins, starches, fibers, and oils in the raw materials, producing beneficial nutrients.

[0024] This invention ferments and decomposes chicken manure, feed dust, waste paper, passion fruit shells, tea dust, eggshells, and microbial agents to fully kill pathogens and roundworm eggs in the raw materials, effectively preventing the spread of soil-borne diseases. It also utilizes waste feed dust, waste paper, and eggshells from farms, increasing their economic value.

[0025] The organic fertilizer provided by this invention is environmentally friendly and odorless, has low production cost and is rich in nutrients, better meets the nutritional needs of plants, can improve the condition of planting soil, and the preparation process is easy to operate manually, the reaction conditions are mild, and there is no need for high temperature and high pressure containers, only basic stirring and heat preservation devices are needed.

[0085] Verification Example

[0086] Based on the quality requirements of passion fruit, zinc and selenium were added to the chicken manure-based passion fruit-specific organic fertilizers prepared in Examples 1-3 and Comparative Examples 1-5, resulting in a zinc content of 0.05 wt% and a selenium content of 0.08 wt%. The different passion fruit-specific organic fertilizers prepared above were applied to passion fruit orchards. After harvest, the soil organic matter, passion fruit pest infestation rate, and passion fruit yield increase in different fertilization groups were measured and statistically analyzed, with the application of traditional compound fertilizers serving as a control. The results are as follows: Figures 1-3 As shown.

[0087] Depend on Figures 1-3 It can be seen that when the chicken manure-based passion fruit-specific organic fertilizer prepared according to Examples 1-3 of this invention is applied, the soil organic matter content is significantly increased, the insect infestation rate of passion fruit is reduced to 2.3%, and the yield of passion fruit increases by 15.2% compared with the application of traditional compound fertilizer.

[0088] This invention utilizes feed dust, turning waste into treasure. Rich in various nutrients, it provides multiple nutrients to the soil, promoting plant growth. The cellulose in waste paper scraps and passion fruit shells can be converted into sugar, providing carbon to the soil. The pulverized waste paper scraps are inexpensive and play a role in loosening, aerating, and absorbing harmful substances during chicken manure fermentation. Tea dust is rich in organic matter and has deodorizing, odor-absorbing, and water-absorbing effects, significantly reducing odors in fertilizers and giving them a tea fragrance. The use of discarded broken eggshells from chicken farms is a waste utilization method that significantly increases the amount of calcium and other trace metals in organic fertilizer. This invention uses deodorizing and fermentation bacteria. The deodorizing bacteria include nitrifying bacteria, Bacillus subtilis, and Pseudomonas, while the fermentation bacteria include Bacillus licheniformis, Bacillus subtilis, Saccharomyces cerevisiae, lactic acid bacteria, and Aspergillus niger. These are introduced in stages into the chicken manure fermentation process: first, the deodorizing bacteria are added to decompose odorous substances in the chicken manure, and then the fermentation bacteria are added to produce beneficial nutrients. The proper formulation of chicken manure, feed dust, waste paper scraps, passion fruit shells, tea dust, eggshells, and biological agents can exert a synergistic effect, resulting in nutritious, odorless organic fertilizer that achieves optimal results.
