Description

Technical Field

[0001] The present invention relates to the technical field of fertilizers, and more specifically, to a method for producing high-efficiency organic fertilizers without fermentation and its preparation method. Background Art

[0002] With the continuous growth of the global population and the increasing agricultural demand, the extensive use of chemical fertilizers has provided strong support for agricultural production. However, the overuse of chemical fertilizers not only has a serious impact on the environment, such as water pollution, soil acidification, and ecological imbalance, but also reduces the organic matter content of the soil and causes the degradation of soil structure in the long term. In order to achieve sustainable agricultural development, improve soil fertility, and reduce environmental pollution, more and more research has begun to focus on the use of organic fertilizers.

[0003] The production of traditional organic fertilizers usually relies on the fermentation process of organic matter. This method requires a long processing time and is prone to generating harmful gases such as ammonia during the fermentation process, which affects the quality of the fertilizer. In addition, the activity of microorganisms gradually decreases over time during the fermentation process, resulting in the difficulty of continuous release of the fertilizer efficiency of organic fertilizers. The excessive moisture generated during the fermentation process also needs to be further processed to improve the quality of the fertilizer, increasing the difficulty of transportation and storage.

[0004] Therefore, the production of organic fertilizers without fermentation has become a research hotspot in recent years. The non-fermentation method does not rely on the action of microorganisms, but processes and transforms organic raw materials through physical and chemical means. Through reasonable material ratio and processing process, the non-fermentation method can produce stable and high-efficiency organic fertilizers in a short time. Compared with the traditional fermentation method, the non-fermentation method has the advantages of short production cycle, low energy consumption, and simple process.

[0005] In recent years, the research on non-fermentation organic fertilizers has gradually developed, and more and more research has focused on improving the nutrient content of fertilizers, improving the application effect of fertilizers, and promoting the improvement of soil structure. By utilizing organic waste, the non-fermentation method can not only reduce the emission of agricultural waste, but also improve the utilization rate of fertilizers, thereby increasing the yield and quality of crops.

[0006] However, although certain progress has been made in the production process of non-fermentation organic fertilizers, there are still some technical problems. For example, how to effectively convert various organic substances into nutrients available to plants through the non-fermentation method in a short time, and how to ensure the stability and persistence of fertilizers during the production process, etc., all require further research and optimization.

[0007] Therefore, developing new and efficient organic fertilizer production processes to make them more environmentally friendly, energy-saving and adaptable is an important research direction in the current agricultural fertilizer field. By breaking through technical bottlenecks, it can better meet the demand for fertilizers in agricultural production and contribute to the realization of sustainable agricultural development.

[0008] Regarding the problems in the related technologies, no effective solutions have been proposed yet. Summary of the Invention

[0017] Furthermore, the interlayer spacing of the nano-layered double hydroxide is 1.2 nm, and the enzyme activity in the immobilized laccase is greater than or equal to 500 U / g.

[0020] Furthermore, the amount of urea embedded in the nano-lignin microspheres is greater than or equal to 65%, and the water holding rate is greater than or equal to 400%.

[0021] According to another aspect of the present invention, there is provided a preparation method for producing a highly efficient organic fertilizer by a non-fermentation method, and the preparation method includes the following steps:

[0022] S1. Use a screw press equipment to dehydrate animal manure, and crush the dehydrated animal manure and animal and plant residues, screen to remove impurities, and desalt and deacetylate shrimp and crab shell powder.

[0023] S2. Preliminarily mix the crushed animal manure and animal and plant residues with minerals, soybean meal, and fish meal, then add seaweed powder, organosilicon, and nano-mineral-enzyme complex for mixing, and then add bio-based functional material, shrimp and crab shell powder, and humic acid-modified bentonite for re-mixing.

[0026] The beneficial effects of the present invention are as follows:

[0027] 1) The present invention proposes a method for producing a highly efficient organic fertilizer by a non-fermentation method. This fertilizer combines a variety of high-efficiency raw materials and functional additives, and has the advantages of comprehensive nutrition, continuous fertilizer efficiency, and strong disease resistance. By reasonably proportioning various raw materials and functional components, not only the nutrient content of the organic fertilizer is improved, but also the stress resistance of crops is enhanced, the soil structure is improved, the soil health is promoted, and a higher fertilizer effect is achieved.

[0028] 2) By using dehydrated animal manure as one of the main raw materials of the fertilizer, the present invention can reduce the moisture content and improve the efficiency of transportation and storage. At the same time, by combining with plant and animal residues such as straw, wood chips, rice husks and fruit peels, it can effectively utilize agricultural waste, reduce the environmental burden, provide the organic matter required by plants, and effectively ensure the balanced supply of fertilizer nutrients.

[0029] 3) By the combined use of seaweed powder and organosilicon, the present invention not only provides trace elements and natural hormones required for plant growth, but also enhances the strength of plant cell walls through the silicon element in organosilicon, improving the disease resistance of crops, especially the ability to resist fungal diseases. In addition, through the combination of earthworm manure and activated carbon, it not only improves the air permeability and water retention capacity of the soil, but also can effectively remove harmful substances in the soil through the adsorption of activated carbon, enhancing the adaptability of crops to environmental stress.

[0030] 4) By using the nano-mineral-enzyme complex, especially through the intercalation of nano-layered double hydroxides, the activity of laccase is enhanced, the degradation of lignin is accelerated, the lignin conversion rate is increased, the rapid decomposition of organic matter is promoted, and more easily absorbable nutrients are provided for plants. In addition, through bio-based functional materials such as nano-lignin microspheres, not only the slow-release effect of the fertilizer is enhanced through its water-holding capacity, but also urea can be encapsulated to achieve the long-term release of slow-release nitrogen, reduce nitrogen loss, and improve fertilizer efficiency.

[0031] 5) Through the synergistic effect of modified zeolite and nano-iron oxide-humic acid complex, the slow-release effect of nutrient elements such as nitrogen, phosphorus and potassium is enhanced, the release period of nitrogen is extended, the waste of fertilizer is effectively reduced, and at the same time, the rapid loss of nutrients in the fertilizer is avoided. In addition, through the combined use of shrimp and crab shell powder and humic acid-modified bentonite, not only the controlled-release effect of the fertilizer is improved through the slow release of chitin, but also the dual slow-release effect is achieved through the delayed release of phosphorus and potassium by humic acid, ensuring the long-term supply of fertilizer nutrients.

[0109] Improve yield and quality: Significantly increase the crop yield and grain plumpness, and reduce the disease incidence rate.

[0110] In summary, by means of the above technical solutions of the present invention, a high - efficiency organic fertilizer produced by a non - fermentation method is proposed. This fertilizer combines a variety of high - efficiency raw materials and functional additives, and has the advantages of comprehensive nutrition, long - lasting fertilizer effect and strong disease resistance. By reasonably proportioning various raw materials and functional components, not only the nutrient content of the organic fertilizer is improved, but also the stress resistance of crops is enhanced, the soil structure is improved, the soil health is promoted, and a higher fertilizer effect is achieved.

[0111] Meanwhile, by using dehydrated animal feces as one of the main raw materials of the fertilizer, the present invention can reduce the moisture content and improve the efficiency of transportation and storage. At the same time, by combining with plant and animal residues such as straw, wood chips, rice husks and fruit peels, agricultural waste can be effectively utilized, the environmental burden can be reduced, and the organic matter required by plants can be provided, which can effectively ensure the balanced supply of fertilizer nutrients. The reasonable proportion of minerals such as rock phosphate, potassium salt and citric acid can provide essential mineral elements for crops, enhance the functionality of the fertilizer, improve the soil pH balance, and enhance the stress resistance of crops.

[0112] Meanwhile, through the combined use of seaweed powder and organosilicon, the present invention not only provides trace elements and natural hormones required for plant growth, but also enhances the strength of the plant cell wall through the silicon element in organosilicon, improving the disease resistance of crops, especially the ability to resist fungal diseases. In addition, through the combination of earthworm cast and activated carbon, not only the air permeability and water retention capacity of the soil are improved, but also harmful substances in the soil can be effectively removed through the adsorption of activated carbon, enhancing the adaptability of crops to environmental adversity.

[0113] Meanwhile, through the use of nano-mineral-enzyme complexes, especially through the intercalation of nano-layered double hydroxides (LDH), the activity of laccase is enhanced, the degradation of lignin is accelerated, the lignin conversion rate is increased, the rapid decomposition of organic matter is promoted, and more easily absorbed nutrients are provided for plants. In addition, through bio-based functional materials such as nano-lignin microspheres, not only the slow-release effect of the fertilizer is enhanced through its water retention capacity, but also urea can be encapsulated to achieve the long-term release of slow-release nitrogen, reduce nitrogen loss, and improve fertilizer efficiency.

[0114] Meanwhile, through the synergistic effect of modified zeolite and nano-iron oxide-humic acid complex, the slow-release effect of nutrient elements such as nitrogen, phosphorus and potassium is enhanced, the release period of nitrogen is extended, the waste of fertilizer is effectively reduced, and the rapid loss of nutrients in the fertilizer is avoided. In addition, through the combined use of shrimp and crab shell powder and humic acid-modified bentonite, not only the controlled-release effect of the fertilizer is improved through the slow release of chitin, but also the dual slow-release effect is achieved through the slow release of phosphorus and potassium by humic acid, ensuring the long-term supply of fertilizer nutrients.

[0115] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
