摘要:

保障土壤健康和肥力是实现可持续农业生产的关键,尤其是在土地退化和粮食安全等全球挑战日益严峻的背景下。传统的土壤质量提升方法通常耗时较长,受制于土壤有机质积累过程的缓慢特性。木本泥炭,作为一种天然腐殖质材料,因其高有机碳含量、高腐殖化程度以及改善土壤结构和微生物活性的能力,成为应对这些挑战的潜在解决方案。本研究综合了关于木本泥炭的性质及其应用的研究,重点探讨了其在增强土壤团聚体稳定性、降低重金属毒性以及减少温室气体排放方面的作用。在土壤改良方面,木本泥炭能够快速提升土壤有机质含量、改善团聚体结构、增强微生物活性,从而提高土壤肥力和作物产量。此外,木本泥炭在污染修复领域也表现出显著优势,通过物理吸附、化学络合及离子交换等机制,降低土壤重金属和有机污染物的生物有效性及毒性,显著改善土壤质量和生态环境。相比传统改良材料如秸秆还田,木本泥炭的长期稳定性使其能够实现更高效的固碳减排目标,助力缓解全球气候变化。在矿区复垦、新垦耕地及设施农业中,木本泥炭展现了独特的应用价值,有效提升土壤物理化学性质和生物功能,促进农业和生态系统可持续发展。未来研究应聚焦木本泥炭的施用策略优化、与其他改良材料的协同效应、对土壤微生物群落的长期影响及环境安全性评估,以实现其在不同农业系统中的高效利用,为全球农业可持续发展提供技术支撑。

Abstract:

Ensuring soil health and fertility is crucial for achieving sustainable agricultural development, especially in the context of escalating global challenges such as land degradation and food security. Traditional soil improvement methods often progress slowly due to the gradual accumulation of organic matter. Woody peat, as a natural humus material, has become a potential solution due to its high organic carbon content, high degree of humification, and its ability to improve soil structure and microbial activity. This study explores the properties and applications of woody peat, focusing on its role in enhancing soil aggregate stability, reducing heavy metal toxicity, and mitigating greenhouse gas emissions. Woody peat can rapidly increase soil organic matter content, improve soil structure, thereby boosting soil fertility and crop yields. Additionally, through mechanisms such as physical adsorption and ion exchange, woody peat can significantly improve soil quality and ecological health. This will ensure the efficient use of woody peat in various agricultural systems, providing important technical support for global agricultural sustainability.

Key words: woody peat, organic matter enhancement, heavy metal passivation, carbon sequestration and emission reduction, mine reclamation, facility agriculture, ecological restoration
