Description

Technical Field

[0001] The invention belongs to the technical field of ecological organic soil production, and in particular relates to a production method of ecological organic soil by utilizing fly ash. Background Art

[0002] Soil improvement is the process of improving the physical, chemical and biological properties of soil through a series of technical means to increase soil fertility and promote crop growth. This usually involves adjustments to soil structure, pH, organic matter content, nutrient balance and microbial activity. Soil improvement aims to solve soil degradation problems such as impoverishment, salinization, erosion, etc., to restore the health of the soil and improve its sustainable utilization. Through reasonable soil improvement measures, the yield and quality of crops can be improved, the ecological environment can be improved, and the sustainable development of agriculture can be promoted. Ecological organic soil is a type of soil that focuses on ecological balance and the recycling of organic matter. It emphasizes the integrity and stability of the soil ecosystem, and provides a high-quality soil environment for crop growth by increasing the content of soil organic matter, improving soil structure, and improving the soil's ability to retain water and fertilizer. Ecological organic soil is usually prepared with natural, non-toxic and non-polluting raw materials, and does not contain chemically synthesized fertilizers and pesticides, thereby ensuring the safety and environmental protection of agricultural products. Fly ash is a solid waste discharged by coal-fired power plants. Large amounts of accumulation not only occupy land resources, but also pose a risk of environmental pollution. If fly ash is effectively utilized, it can be converted into a valuable soil conditioner and used in agriculture, forestry and animal husbandry to improve soil quality and reduce the pressure of waste on the environment. In view of this, the present invention proposes a production method for producing ecological organic soil using fly ash. Summary of the invention
