Description

Technical Field

[0001] The present invention relates to the technical field of agricultural fertilizers, in particular to a flavonoid compound fertilizer with yield increasing and insecticidal effects and a preparation method thereof. Background Art

[0002] With the rapid development of agriculture, improving crop yields, reducing pesticide residues, and increasing fertilizer utilization efficiency have become important issues in modern agriculture. At present, the fertilizer utilization efficiency in China is still at a relatively low level, which not only leads to a decline in soil fertility and a reduction in crop quality, but also causes serious environmental pollution problems. In addition, the overuse and residue problems of pesticides have become increasingly prominent, posing a major hidden danger to food safety and the ecological environment.

[0003] To solve these problems, in recent years, China has conducted extensive exploration and innovation in agricultural technologies. On the one hand, by promoting technologies such as precision fertilization and precision pesticide application, the utilization efficiency of chemical fertilizers and pesticides has been improved; on the other hand, research and application of green intelligent fertilizers, biological control technologies, etc. have been carried out to reduce the use of chemical fertilizers and pesticides.

[0004] In addition, using organic fertilizers and microbial inoculants to improve soil structure and soil fertility has also become an important means to increase fertilizer utilization efficiency. Organic fertilizers can not only provide rich nutrient elements, but also improve the physical and chemical properties of the soil, while microbial inoculants can release nutrients that plants can absorb by decomposing organic substances, further improving the utilization efficiency of fertilizers.

[0005] However, the existing technologies still have certain limitations. For example, the nutrient release of traditional fertilizers does not match the crop requirements, resulting in serious nutrient losses; while some new fertilizers, although theoretically having high efficiency, still face problems such as high costs and complex technologies in actual applications. Therefore, developing a compound fertilizer that can not only increase crop yields, effectively control pests, reduce the amount of pesticides used, but also improve fertilizer utilization efficiency and reduce nutrient element losses is of great significance for promoting the sustainable development of agriculture. Summary of the Invention

[0006] The present invention specifically relates to a flavonoid compound fertilizer and a preparation method thereof. The flavonoid compound fertilizer can not only significantly increase crop yields, effectively control pests, reduce the amount of pesticides used, lower pesticide residues, but also improve fertilizer utilization efficiency, reduce nutrient element losses, and protect the environment.

[0007] To achieve the above object, the present invention provides the following technical solutions:

[0008] The first aspect of the present invention is to provide a flavonoid compound fertilizer, which is composed of the following raw materials in parts by weight: 20-40 parts of flavonoid extract, 50-100 parts of organic fertilizer, 10-30 parts of microbial inoculant, 20-40 parts of mineral fertilizer, and 10-20 parts of insecticidal adjuvant.

[0009] As a further technical solution, the flavonoid extract includes any two or more of quercetin, rutin, and daidzein.

[0011] As a further technical solution, the microbial inoculant includes any two or more of Bacillus subtilis, Bacillus megaterium, and Bacillus mucilaginosus.

[0012] As a further technical solution, the mineral fertilizer includes any two or more of ammonium sulfate, single superphosphate, and potassium sulfate.

[0013] As a further technical solution, the insecticidal adjuvant includes any two or more of matrine, azadirachtin, and rotenone.

[0014] The second aspect of the present invention is to provide a preparation method of a flavonoid compound fertilizer, which includes the following steps:

[0016] (2) Add 10-30 parts of microbial inoculant to the blender and continue to stir for 5-10 minutes;

[0017] (3) Add 20-40 parts of flavonoid extract to the blender and continue to stir for 3-5 minutes;

[0018] (4) Add 10-20 parts of insecticidal adjuvant to the blender and continue to stir for 2-3 minutes;

[0019] (5) Granulate at a temperature of 50-80°C and a humidity of 2.5%-7.5%, and control the particle size to be 3-5 mm;

[0020] (6) Dry at a temperature of 50-60°C for 4 hours, package, and obtain the flavonoid compound fertilizer.

[0021] Compared with the prior art, the present invention has the following beneficial effects:

[0022] 1. Significantly increase crop yields: By adding flavonoid extracts, organic fertilizers, microbial inoculants, and mineral fertilizers, this compound fertilizer can significantly enhance the growth performance of crops. The active ingredients in flavonoid extracts can enhance the antioxidant capacity and stress resistance of plants, promote photosynthesis efficiency, and thus increase the biomass and yields of crops.

[0023] 2. Effectively control pests, reduce the amount of pesticide used, and lower pesticide residues: The natural insecticidal aids (such as matrine, azadirachtin, rotenone) added in this compound fertilizer have significant insecticidal and antifeedant effects, and can effectively control a variety of common pests, such as aphids, borers, and underground pests. Due to the synergistic effect of these natural ingredients, the amount of pesticide used can be significantly reduced by 30% - 40%, thus greatly reducing pesticide residues and minimizing the negative impact on the environment and ecosystem.

[0024] 3. Improve fertilizer utilization rate, reduce nutrient element loss, and protect the environment: The microbial inoculants (such as Bacillus subtilis, Bacillus megaterium, Bacillus mucilaginosus) in this compound fertilizer can decompose organic substances in the soil, release nutrient elements that can be absorbed by plants, and at the same time promote the growth of plant roots and improve the absorption efficiency of nutrients. In addition, the reasonable ratio of organic fertilizer and mineral fertilizer can reduce the fixation and loss of nutrients in the soil, increase the fertilizer utilization rate by 20% - 30%, and effectively reduce environmental pollution.
