Description

Technical Field

[0001] This utility model relates to the field of agricultural ecological breeding technology, and in particular to an ecological circular farming system. Background Technology

[0002] Plateau regions are characterized by low average annual temperatures, thin oxygen, and fragile ecosystems. Traditional agriculture faces the following problems: fish farming lacks a scientific wastewater treatment system, and fish wastewater is directly discharged into the surrounding environment, leading to increased concentrations of nutrients such as nitrogen and phosphorus in the water, causing eutrophication and disrupting the aquatic ecological balance; in livestock and poultry farming, organic fertilizers such as chicken manure are usually piled up in the open and cannot be effectively recycled and utilized. Due to the thin oxygen in high-altitude areas, microbial decomposition efficiency is low, resulting in severe nitrogen volatilization losses (>30%). This not only wastes resources but may also pollute the atmosphere through ammonia volatilization. Traditional agriculture is mainly based on single planting or breeding, lacking a cyclical model that integrates planting and breeding, making it impossible to form a complete industrial chain. This leads to low production efficiency and insufficient supply of agricultural products in high-altitude areas, requiring heavy reliance on external inputs, increasing production costs and logistical pressures, and weakening the competitiveness of local agriculture. In pursuit of higher yields, farmers overuse chemical fertilizers. However, the low average annual temperature in high-altitude areas results in weak soil microbial activity and low effective utilization of chemical fertilizers. Unabsorbed nutrients accumulate in the soil over a long period, leading to soil compaction, increased salinization, and organic matter content below 1.5% (far below the standard for healthy soil). This threatens the ecological balance of the high-altitude areas, whose ecosystems are inherently fragile and difficult to restore once damaged.

[0003] These problems not only constrain the sustainable development of agriculture in plateau regions but also pose a potential threat to their ecological environment and socio-economic stability. Therefore, it is urgent to explore ecological agricultural models suitable for the characteristics of plateau regions to achieve a win-win situation for both green agricultural development and ecological protection.
