中文摘要:
      伴随着土壤的不断开发和利用,土壤污染、退化问题愈发严重,严重限制了土地的生产力,由此土壤调理剂应运而生。合理使用土壤调理剂产品能有效改善土壤物理性状、化学性状,补充土壤中的营养元素,同时对土壤微生物群落的结构和数量进行调整,从而改善土壤的障碍因子,使之可再次进行投入高质高效的农作物生产活动。但土壤调理剂的不合理施用会直接引起土壤退化加剧甚至产生二次污染,同时长期施用土壤调理剂也可能会对土壤生态系统的结构和功能造成一定影响,导致土壤的产能与品质下降,引发农产品安全等相关问题。本文根据现阶段我国土壤调理剂研究及应用状况,分析不同类型的土壤调理剂在施用过程中可能产生的环境风险,并对土壤调理剂的施用提出了展望及管理建议。
英文摘要:
      With the continuous development and utilization of soil, the problem of soil pollution and degradation is becoming more and more serious, which greatly limits the productivity of land. Consequently, soil conditioners emerge as the times require. The rational use of soil conditioner products can effectively improve the physical and chemical properties of soil, supplement nutrient elements in soil, and adjust the structure and quantity of the soil microbial community, thus improving soil obstacle factors. This allows soil to be put back into high quality and efficient agricultural production activities again. However, the unreasonable application of soil conditioners directly leads to soil degradation and even secondary pollution. At the same time, long-term application of soil conditioners may also have an impact on the structure and function of the soil ecosystem, resulting in the decline of soil productivity and quality, leading to related problems such as the safety of agricultural products. According to the current situation of research and application of soil conditioners in China, this paper analyzes the possible environmental risks of different types of soil conditioners in the process of application. It puts forward prospects and management suggestions for the application of soil conditioners.
