摘要
本文从改进肥料施用技术、改性现有肥料、阻断农田氮磷损失的物理和化学措施、运用生物学途径以及植物生长调节物质等方面综述了当前提高氮、磷肥料利用效率 ,减少氮、磷对环境污染的途径。
The strategies of increasing fertilizer use efficiency and controlling the losses of N and P were discussed in this paper, which included proper fertilizer management and practice, using controlled-release fertilizers, physical and chemical methods blocking the pathways of fertilizer losses, selecting new crop genotypes and exploiting plant growth regulators.
