甘肃省推进马铃薯化肥农药减施的思考

Some Reflections on Promotion of Potato Chemical Fertilizer and Pesticide Reductions in Gansu Province

化肥农药是农业生产中不可或缺的生产资料,在提高农产品产量的同时,对生态环境和食品安全也产生了不利影响,已经成为农业面源污染的主要来源。因此,科学合理地使用化肥农药,是确保农产品高产、优质的重要手段。马铃薯是甘肃省第三大粮食作物,选择马铃薯开展化肥农药减施研究具有重要的现实意义。通过对甘肃省马铃薯生产现状和面临问题的综合分析,确定了甘肃省推进马铃薯化肥农药减施的总体目标,提出了重点研究的技术内容,需要集成的区域技术模式以及推进的具体措施。

As indispensable agricultural materials,chemical fertilizer and pesticide(CFPs)not only increase agricultural output,but also have a negative impact on ecological environments and food safety.They have been the main sources of agricultural non-point source pollution.Therefore,scientific and reasonable application of CFPs is the crucial approach to guarantee high-yield and high-quality agricultural products.Since potato is the third largest food crop in Gansu Province,the researches on CFPs reduction for potato are of great practical significance.After comprehensive analysis on potato production status and problems,the overall objectives of CFPs reduction have been defined.Furthermore,the key techniques,regional Integrated technical patterns and specific promotion measures have been put forward.
