Description

Technical Field

[0001] The present invention relates to the technical field of soil conditioning, and in particular to a microbial composite soil conditioner and a preparation method thereof. Background Art

[0002] With the rapid development of agriculture, soil quality problems have become increasingly prominent, including soil compaction, decreased fertility, salinization, and heavy metal pollution, which have seriously affected the growth and yield of crops. Traditional soil improvement methods mainly increase soil fertility by applying chemical fertilizers and organic fertilizers, but these methods are often costly, have short-term effects, and are prone to environmental pollution.

[0003] Microbial composite soil conditioner is a new type of soil improver. By adding beneficial microbial agents and organic materials, it can improve soil structure, increase soil fertility, enhance soil microbial activity, reduce soil salinity and heavy metal content, thereby increasing crop yield and quality.

[0004] The composite microbial fermentation soil conditioner proposed in the Chinese invention patent application number: CN201710894762.4 includes the following raw materials by weight: 290-315 parts of urea, 290-315 parts of nitrogen-potassium compound fertilizer, 235-260 parts of ammonium dihydrogen phosphate, 40-60 parts of potassium pyrophosphate, 1-3 parts of chelated iron, 3-5 parts of chelated zinc, 80-100 parts of the fermentation product of lignite or weathered coal and microbial agent, and 900-1100 parts of anti-caking agent; the composite microbial fermentation soil conditioner provided by the present invention contains humic acid rich in mineral sources, which solves the problems of soil compaction, acidification, and salinization, and has a good promoting effect on plant roots, and has greatly improved other corresponding agronomic traits. The microbial agent has the ability to fix nitrogen, dissolve phosphorus, dissolve potassium, produce plant hormones, or secrete antibiotics, which promotes the circulation of materials and nutrient supply in the soil.

[0005] The traditional soil conditioners commonly found on the market are mainly inorganic fertilizers, single microbial preparations and simple organic waste compost. These conditioners have the following significant deficiencies in practical applications:

[0006] Traditional soil conditioners can only provide a limited number of nutrients, resulting in a lack of other essential elements in the soil and failing to fully meet the needs of crop growth. For example, some conditioners only focus on macronutrients such as nitrogen, phosphorus, and potassium, while ignoring the importance of micronutrients such as iron, zinc, and manganese. This unbalanced nutrient supply not only limits the growth potential of crops, but also causes symptoms of malnutrition in crops, affecting yield and quality.

[0007] Many soil conditioners contain only a single type of microorganisms with low activity, making it difficult for them to adapt to the changing environmental conditions of the soil. After entering the soil, these microorganisms often have difficulty effectively colonizing and functioning due to their lack of sufficient adaptability and competitiveness. In addition, a single type of microorganism cannot form an effective microbial community and cannot fully exert the synergistic effect between microorganisms, thus affecting the soil improvement effect and the healthy growth of crops.

[0008] The nutrients in some existing conditioners are released too quickly, resulting in a short effective period and the need for frequent use, which not only increases labor costs but also easily leads to nutrient waste and environmental pollution. Rapidly released nutrients are easily leached or volatilized and cannot be fully absorbed and utilized by crops. In addition, frequent application also leads to the destruction of soil structure, affecting the physical properties and biological activity of the soil, further exacerbating soil problems.

[0009] Existing soil conditioners contain heavy metals or other harmful substances. Long-term use will cause soil pollution, which will affect crop quality and environmental safety. For example, some inorganic fertilizers contain heavy metals such as cadmium and lead. After these heavy metals accumulate in the soil, they will not only affect the growth of crops, but also pose a threat to human health through the food chain. In addition, some chemically synthesized conditioners produce harmful intermediates during the degradation process, which have a negative impact on the environment and biodiversity. Therefore, we have made improvements to this and proposed a microbial composite soil conditioner and its preparation method. Summary of the invention

[0188] 1. Control group setting: Set up soil without any soil conditioner as the control group.

[0189] 2. Experimental group setting: The prepared microbial composite soil conditioner was applied to the experimental soil at different doses (low, medium, and high).

[0190] 3. Soil sample collection: Samples were collected from the control and experimental soils before and after the application of soil conditioners.

[0191] 4. Soil analysis: The physical properties (such as structure and density), chemical properties (such as pH value and nutrient content) and biological properties (such as microbial diversity and activity) of the collected soil samples are analyzed.

[0192] 5. Plant growth test: Plant the same crops in the soil of the control group and the experimental group, and observe and record the growth of the crops, including growth rate, yield, and quality.
