Biological fertilizer and preparation method thereof

Abstract

The invention relates to the technical field of biological fertilizers, and especially relates to a biological fertilizer and a preparation method thereof. An arc-shaped disc used for bearing the biological fertilizer comprises a carbon cover barrel, a carbon column barrel and an arc-shaped frame. Due to the fact that the added biological fertilizer is prone to loss to all positions in soil blocksunder the rainwater condition, the content of nutrients absorbed by crop root areas is reduced, nutrient supply in the crop growth process is affected, and then the use effect of the biological fertilizer is weakened. Therefore, the storage state of the biological fertilizer under different conditions of the natural environment is protected through the carbon structure of the arc-shaped disc, itis ensured that the biological fertilizer acts on a crop root system area in a land parcel, the release rate of nutrients in the biological fertilizer is balanced through gradual conversion of biological carbon nutrient substances by microbial florae in the crop growth process, the yield of the biological fertilizer is increased. and the time for finally decomposing the carbon structure of the mechanism is controlled to completely decompose the carbon structure in the biological fertilizer, so that the application effect of the biological fertilizer is improved.

Description

technical field [0001] The invention relates to the technical field of biological fertilizers, in particular to a biological fertilizer and a preparation method thereof. Background technique [0002] Biological fertilizer refers to biological fertilizer, which is a product that enables plants to obtain specific fertilizer effects through the life activities of microorganisms. Among them, biochar prepared from agricultural and forestry waste is conducive to the recycling of resources, and the release of nutrients stored in biochar is completed. Finally, the remaining biochar can alleviate the compaction of the soil, making biochar an excellent carrier for biofertilizers; for the introduction of biofertilizers and their preparation methods, please refer to: Li Yanmei et al., Biochar-based fertilizer synergistic technology and preparation process research progress analysis [J], Journal of Agricultural Machinery, 2017(No.3), 1-13. [0003] At present, the use of biological fert...

AI Technical Summary

Problems solved by technology

The fertilizer solves the costly methods of coating, wrapping, encapsulating, and coating of the existing slow-release fertilizers, and can reduce the occurrence of crop diseases and insect pests, adjust and maintain the moisture content in the soil, improve the air permeability of the soil, and maintain fertilizer efficiency , promote plant growth, and increase the microorganisms that promote plant growth; the fertilizer in this technical solution is a complex containing multiple nutrients, not a chemical fertilizer with a single nutrient, and is rich in nutrients such as nitrogen, phosphorus, and potassium. Contains amino acids, humic acid, calcium, sulfur, zinc, iron, boron and more than 20 kinds of "quality elements" necessary for crops, which play a role in regulating the balanced nutrition of the soil; After that, it will be lost to various positions in the soil with the water flow in the rainy environment, which weakens the nutrient supply effect of the bio-fertilizer on the crops, and causes waste of nutrients in the bio-fertilizer
