摘要
随着对农作物产量增长需求的提高,化肥的施用量也越来越大,由于施肥量不合理、施用方法不科学等原因导致的环境问题日益突显。介绍施肥对土壤环境的影响,阐述土壤重金属污染现状,并提出防治土壤重金属污染的有效措施。
With the growth in grain production, the amount of chemical fertilizer is also growing. But because of unreasonable fertilization mechanism, inappropriate fertilizing method and so on, the environmental problems caused by the fertilization are becoming increasingly prominent.
