化肥减量增效的意义与技术措施

化肥不合理使用和农业废弃物利用不充分等,是造成种植业面源污染的主要因素。随着测土配方施肥、水肥一体化、耕地质量提升等项目的示范推广,化肥使用总量逐年下降,减少了对环境的污染。文章根据化肥减量增效实施的实践,分析了实施化肥减量增效的意义,介绍了推广该技术的具体措施。

Significance and Technical Measures of Reducing and Increasing Efficiency of Chemical Fertilizer

Unreasonable use of chemical fertilizer and inadequate use of agricultural waste are the main factors that cause non-point source pollution of planting industry.With the demonstration and promotion of soil testing and formula fertilization,water and fertilizer integration,farmland quality improvement and other projects,the total amount of fertilizer use has decreased year by year,reducing the environmental pollution.According to the practice of reducing and increasing the efficiency of chemical fertilizer,this paper analyzes the significance of reducing and increasing the efficiency of chemical fertilizer,and introduces the concrete measures of popularizing the technology.
