Description

Technical Field

[0001] This invention relates to the field of agricultural organic waste resource utilization technology, and particularly to the field of preparing organic fertilizer from agricultural organic waste. Specifically, it refers to a method for rapidly preparing immune-type organic fertilizer from agricultural organic waste and the immune-type organic fertilizer prepared therefrom. Background Technology

[0002] Agricultural organic waste refers to organic byproducts generated throughout the entire agricultural production process. It is diverse and complex in composition, and improper handling can pose a serious threat to the ecological environment and sustainable agricultural development. Agricultural organic waste is mainly divided into three categories: plant waste, animal waste, and other agricultural solid waste. It is urgent to address the environmental problems it causes and to explore its resource potential.

[0003] Plant-based waste constitutes the largest category in agricultural production, including crop stalks (such as corn stalks, rice stalks, and fruit vines), forestry residues (such as forest pruning materials and aquatic plants), and agricultural product processing residues (such as fruit peels and vegetable leaves).

[0004] Plant waste is an excellent raw material for organic fertilizer. Organic fertilizer is usually produced by windrow composting, but the production process has relatively strict requirements: ① The production cycle is long, usually requiring several months; ② It is difficult to reach the required high temperature for composting, and it is difficult to completely kill harmful organisms such as insect eggs; ③ Resource utilization is difficult, and it is not easy to meet the national standard for organic fertilizer NY / T 525-2021; ④ The potential for value enhancement is limited, as its loose material form makes it difficult to mix evenly with other fertilizer synergists.

[0005] Because different types of plant waste vary in terms of moisture content, organic matter content, pH, and total nutrients, using only a single material for immune microbial composting and fermentation can easily lead to unstable fermentation quality and affect the fertilizer efficiency of the final product.

[0006] Therefore, it is desirable to provide a method for preparing organic fertilizer from agricultural organic waste, which can make full use of agricultural organic waste to prepare organic fertilizer, and the prepared organic fertilizer has stable quality and contains a large number of plant immune-activating proteins, thereby solving the problems of unstable quality and immune and disease-resistant functionalization of existing organic fertilizers and enhancing the value of organic fertilizer.

[0081] (4) The dehydrated material is screened using a finished product screening machine with a screen aperture of 1 cm to prepare immune-type organic fertilizer V.

[0082] Comparative Example 1

[0083] Basically the same as Example 1, except that in step (2), a common straw composting microbial agent (containing Bacillus subtilis, Bacillus amyloliquefaciens and Bacillus licheniformis in a mass ratio of 1:1:1) is added, and finally, comparative organic fertilizer I is obtained.

[0084] Comparative Example 2

[0085] Basically the same as Example 1, except that no biochemical potassium humate is added in step (2), and finally comparative organic fertilizer II is obtained.

[0086] Comparative Example 3

[0087] Basically the same as Example 1, except that no urea is added in step (2), and finally comparative organic fertilizer III is obtained.

[0088] Comparative Example 4

[0089] Basically the same as Example 1, except that in step (2), the horizontal drum fermentation chamber is not used for fermentation, and the fermentation mixture is directly stacked in step (3) to finally obtain the comparative organic fertilizer IV.

[0090] Comparative Example 5

[0091] Basically the same as Example 1, except that in step (3), only horizontal drum fermentation chamber fermentation is carried out, and stacking aging is not carried out, and finally comparative organic fertilizer V is obtained.

[0092] Detection Examples

[0093] The plant waste shreds from Examples 1-5 were tested for the content of relevant components, and the results are shown in Table 1 below:

[0094] Table 1. Test results of relevant component content in plant-based waste pulverizers from Examples 1-5

[0095]

[0096] The content of relevant components in the immune-type organic fertilizers I-V prepared in Examples 1-5 was tested, and the results are shown in Table 2 below:

[0097] Table 2. Test results of the content of I-V related components in the immune-type organic fertilizer prepared in Examples 1-5

[0098]

[0099] The contents of relevant components in the comparative organic fertilizers I-V prepared in Comparative Examples 1-5 were tested, and the results are shown in Table 3 below:

[0100] Table 3. Test results of the content of relevant components I-V in the comparative organic fertilizers prepared in Comparative Examples 1-5

[0101]

[0102] The test results above show that, compared with all the comparative examples, all the examples have significantly shortened the total production time, significantly increased the maximum composting temperature, and all produced plant immune activation protein NAC-189 efficiently. This protein has the effect of improving plant immunity and disease resistance.

[0103] Compared with Example 1, Comparative Example 1 shows that the thermoresistant immune-promoting microbial agent that produces the plant immune-activating protein NAC-189 can effectively accelerate the degradation and nutrient conversion process of materials, shorten production time, and improve the degree of composting. Comparative Example 2 shows that biochemical potassium fulvate is an essential component for maintaining the optimal fermentation environment and nutrient balance. The lack of biochemical potassium fulvate leads to a significant deviation of the product pH from neutral and a substantial decrease in total potassium content, resulting in low total nutrients. Biochemical potassium fulvate plays a role in regulating the pH of the system and preventing potassium loss. Comparative Example 3 shows that due to the lack of exogenous nitrogen supplementation, microbial activity is limited. This resulted in a decrease in the conversion efficiency of nitrogen in the material, with its total nitrogen content being much lower than that of Example 1. Comparative Example 4 skipped the composting and fermentation stage and directly carried out stacking aging. Ultimately, all key fertilizer efficiency indicators (including organic matter, total nitrogen, total phosphorus, total potassium, and total nutrients) of the product of Comparative Example 4 were significantly lower than those of Example 1, proving that without the active fermentation process at the front end, the material could not achieve full degradation and efficient nutrient conversion. Comparative Example 5 only carried out fermentation in a horizontal drum fermentation chamber without stacking aging. To meet the indicators of NY / T525-2021, it was necessary to extend the fermentation time, which resulted in an extension of 7.5 days in the total production time.

[0104] Therefore, this invention provides a method for rapidly preparing immune-type organic fertilizer from agricultural organic waste. By employing an integrated process combining "front-end fermentation" and "back-end aging," and adding a specific formula consisting of a heat-resistant immune-activating microbial agent that produces plant immune-activating proteins, biochemical potassium humate, and urea during fermentation, the method significantly enhances the degree and efficiency of material decomposition while efficiently producing plant immune-activating proteins. These proteins enhance plant immunity and disease resistance. Using this method, the prepared immune-type organic fertilizer product can achieve an organic matter content of over 45%, a total nutrient content (N+K2O+P2O5) of over 6.2%, and a plant immune protein content between 1-1.5‰, all of which meet the current national organic fertilizer standards.

[0105] This invention not only provides an effective way to efficiently and valuablely utilize various types of plant waste, but also improves processing efficiency and product quality through optimized process combinations, providing a practical technical solution for the harmless, large-scale treatment and resource recycling of agricultural waste. Using different types of plant waste as fermentation materials, plant immune proteins are produced, which, together with organic fertilizer, form an immune-type organic fertilizer. This fertilizer possesses the functions of organic fertilizer while also providing disease resistance, greatly enhancing its value and demonstrating promising prospects for large-scale application.

[0106] In summary, the method for rapidly preparing immune-type organic fertilizer from agricultural organic waste of the present invention can make full use of agricultural organic waste to prepare organic fertilizer, and the prepared organic fertilizer has stable quality and contains a large number of plant immune-activating proteins. It solves the problems of unstable quality and immune and disease-resistant functionalization of existing organic fertilizers, enhances the value of organic fertilizer, and is suitable for large-scale promotion and application.

[0107] Therefore, it is evident that the objective of this invention has been fully and effectively achieved. The function and structural principles of this invention have been demonstrated and explained in the embodiments. Any modifications can be made to the implementation methods without departing from these principles. Therefore, this invention includes all modified embodiments based on the spirit and scope of the claims.
