扫码查看
提高肥料利用率、减少肥料损失是目前农业生产中急需解决的重要问题.针对我国肥料利用率低、氮肥损失严重的现状,综述了肥料利用率低的原因及提高肥料利用率的有效途径:主要包括推广缓/控释肥料;进行精准配方施肥;改进施肥方法.
Current Situation of Fertilizer Use in China and the Method to Improve Chemical Fertilizer Utilization Efficiency
It is of great importance to improve fertilizer utilization efficiency and to reduce the loss for farming production. In the paper, some traditional methods to improve fertilizer using rates, causes for low utilization rates, and some efficient ways to improve use efficiency, like slow/controlled release fertilizer popularization, accuracy formulation fertilization and fertilization improving method were summarized.
