东北黑土地农田除草剂污染过程与消减技术研究进展与展望

除草剂是保障黑土粮仓粮食供给的重要生产资料。东北黑土区除草剂的高频高强度施用，可能导致其在土壤中残留累积，从而影响后茬作物生长，成为轮作换茬、种植结构调整的瓶颈。因此，开展黑土地除草剂污染过程与消减关键技术研究，对保障黑土地农业绿色可持续发展具有重要的科学意义。系统分析了黑土地农田除草剂污染过程与消减技术研究进展与发展趋势，指出了目前该研究领域存在的科学与技术问题，提出了我国黑土地农田除草剂污染过程与消减技术的研究思路与重点方向，以推动我国黑土地农田除草剂污染修复理论与技术的发展。

Research Progress and Perspective on the Pollution Process and Abatement Technology of Herbicides in Black Soil Region in Northeastern China

Herbicides are important inputs in the agricultural chain of production required for the improved productivity of black soil granary. Nevertheless, the high-frequency and high-intensity application of herbicides in the black soil region in northeastern China might lead to their residual accumulation in soil. Thus, this affects the growth of after reap crops and becomes the bottleneck of crop rotation and planting structure adjustment. Therefore, research on the herbicide pollution process and key abatement technologies are of great scientific significance to ensure green sustainable development of agriculture in the black soil region. This paper systematically analyzed the research progress and development trend on herbicide pollution process and abatement technology in the black soil region. The scientific and technical problems existing in this research field was pointed out. Besides, we also put forward research ideas and key directions of herbicide pollution process and abatement technology in the black soil region in China, so as to promote the development of herbicide pollution and remediation theory and technology in the black soil region in China.
