Description

Technical Field

[0001] The present invention relates to the technical field of soil conditioning, and specifically provides a self-reproducing microbial soil conditioning agent. Background Art

[0002] With the accelerating advancement of industrialization and agricultural modernization, environmental pollution problems have become increasingly severe, having a non-negligible impact on the land ecosystem. Among them, problems such as soil pollution, degradation, and overuse of chemical fertilizers and pesticides are particularly prominent, leading to a decline in land quality and severely affecting crop yields and quality. To address these challenges, the use of self-reproducing microbial soil conditioning agents has become increasingly important.

[0003] In agricultural production, long-term over-reliance on chemical fertilizers and pesticides can disrupt the natural balance of the soil, resulting in problems such as a reduction in soil organic matter, an imbalance in the microbial population, and a loose soil structure. These problems not only reduce soil fertility but also increase the incidence of pests and diseases, severely affecting crop growth and yields.

[0004] In the Chinese Patent Application Publication Specification CN200610033471.8, an antibacterial compound fertilizer and its production method are disclosed. The antibacterial compound fertilizer is made from the following raw materials in percentages: 80% - 99% of compound fertilizer, and 1% - 20% of biological antibacterial granular fertilizer. Among them, the biological antibacterial granular fertilizer is composed of 50% of compound biological potassium fertilizer and 50% of biological multi-antibacterial fertilizer, and its effective bacteria are ≥ 200 billion / kg - 400 billion / kg.

[0005] Although the above invention improves the utilization rate of compound fertilizer, decomposes residual chemical fertilizers in the soil, promotes the absorption of nitrogen, phosphorus, and potassium and the growth of crops, and inhibits the reproduction of harmful bacteria in the soil; it has a good control effect on crop continuous cropping diseases, soil-borne diseases, etc. However, with the development of modern life, the regulation of this product on the soil is limited, and it cannot achieve a more efficient and self-regulating ecological-friendly soil conditioning product that can improve the soil environment. Summary of the Invention

[0006] (1) Technical Problems to be Solved

[0007] Aiming at the deficiencies of the prior art, the present invention provides a self-reproducing microbial soil conditioning agent, which solves the problem of not being able to achieve a more efficient and self-regulating ecological-friendly soil conditioning that can improve the soil environment.

[0008] (2) Technical Solutions

[0009] To achieve the above object, the present application provides a self-reproducing microbial soil conditioning agent, adopting the following technical solutions:

[0010] A self-propagating microbial soil conditioning agent comprises: 13-21 parts by weight of Olsonella, 11-22 parts by weight of Bacillus licheniformis, 10-15 parts by weight of Jiaodong-like Bacillus, 20-23 parts by weight of Bacillus megaterium, 15-25 parts by weight of Bacillus thuringiensis, 15-20 parts by weight of Bacillus laterosporus, 12-25 parts by weight of Bacillus mucilaginosus, and 240-365 parts by weight of plant organic matter.

[0011] Preferably, the plant organic matter is one or a mixture of plant by-products such as wine dregs, vinegar dregs, soybean dregs, bagasse, beet pulp, etc.

[0012] Among them, it should be specifically noted that the use of wine dregs, vinegar dregs, soybean dregs, bagasse and beet pulp as organic additives is extremely advantageous for the self-regulating growth of the soil. The use of local existing plant production by-products as raw materials for plant organic matter not only rationally utilizes ecological resources, but also provides high-quality ingredients for the products prepared subsequently.

[0013] A method for preparing a self-propagating microbial soil conditioning agent comprises the following steps:

[0014] S1: crush the plant organic raw materials with a crusher, sieve through 80-120 mesh, fumigate at high temperature for 2-3 hours, keep them moist, and set aside;

[0015] S2: The prepared organic matter is used as a base material, and Olsonella, Bacillus licheniformis, Bacillus jiaodong-like, Bacillus megaterium, Bacillus thuringiensis, Bacillus laterosporus, and Bacillus colloids are added in sequence according to the mass proportion of the above formula, and then 15°C-25°C distilled water is added to make the humidity reach 25%-35%;

[0016] S3: fermenting the mixture prepared in S2, maintaining the temperature at 55°C-65°C for 6-8 days;

[0017] S4: The product obtained after fermentation is packaged in bags to obtain a self-propagating microbial soil conditioning agent.

[0018] Among them, it should be specifically noted that the plant organic raw materials, after being crushed and screened, are subjected to high-temperature fumigation treatment, which achieves a certain degree of disinfection effect and provides a good culture environment for other microorganisms as a base material.

[0019] Preferably, the fermentation time of 6-8 days is sufficient for the microorganisms to fully decompose the organic matter and produce sufficient beneficial substances.

[0020] Preferably, the Olsonella has a positive effect on plant growth, can promote seed germination and seedling growth, thereby establishing a positive feedback connection between plants and soil, further achieving the effect of self-reproducing microorganisms conditioning the soil.

[0021] Preferably, the Bacillus licheniformis can inhibit the reproduction of pathogenic bacteria in the soil and the invasion of plant roots, reduce soil-borne diseases of plants, improve the soil aggregate structure, enhance the water storage and energy storage capacity of the soil, effectively increase the soil temperature, and alleviate the continuous cropping obstacle.

[0022] Preferably, the Bacillus mucilaginosus can decompose ores (such as silicate minerals), increase soil fertility, and improve the utilization rate of chemical fertilizers. It produces substances such as organic acids, extracellular polymers, and enzymes, which undergo an exchange reaction with minerals to release medium and trace elements such as soluble calcium, sulfur, magnesium, zinc, molybdenum, and manganese.

[0023] Preferably, the Bacillus megaterium can degrade insoluble phosphorus compounds in the soil into soluble substances that can be absorbed by crops. It has a nitrogen fixation and synergistic effect when co-cultured with Bacillus sphaericus, thereby improving the soil fertility.

[0024] Preferably, the Bacillus thuringiensis can kill pests by parasitizing in the pests and producing toxins, which can reduce the usage amount of chemical pesticides, thereby indirectly promoting the restoration of the soil ecological balance.

[0025] Preferably, the Bacillus laterosporus can also decompose organic substances in the soil, improve the soil structure, form a good aggregate structure, and produce a variety of antibacterial substances to inhibit the growth and reproduction of pathogenic bacteria, reduce the occurrence of plant diseases, activate mineral elements in the soil that are difficult to be absorbed by plants, and improve the effectiveness of the elements.

[0026] Preferably, the Bacillus mucilaginosus can regulate substances such as organic acids, amino acids, polysaccharides, and hormones that are beneficial for plant absorption and utilization during the growth and reproduction process.

[0027] (III) Beneficial effects

[0028] The present invention provides a self-reproducing microbial soil conditioner, which has the following beneficial effects:

[0029] The self-reproducing microbial soil conditioner obtained by the above method can, through the fermentation of microorganisms, decompose organic substances, increase the organic matter content in the soil, improve the soil aggregate structure, and enhance the air permeability and water retention and fertilizer retention capacity of the soil. At the same time, during the reproduction and metabolism of microorganisms in the soil, it promotes the root development and nutrient absorption of crops, improves the growth rate and yield of crops. The various Bacillus spp. added form a dominant flora in the soil, which can inhibit the growth and reproduction of pathogenic bacteria, reduce the occurrence of crop diseases, and further achieve a more efficient, self-regulating, and ecological-friendly soil conditioning situation for improving the soil environment.
