摘  要：
采用随机问卷调查的方法调查了山东省桓台县唐山镇、陈庄镇、果里镇1996、2003年农业生产中化肥、农药投入及粮食产出的现状,分析探讨了该县化肥、农药投入的合理性以及对农村环境存在的潜在威胁。调查结果表明,桓台县施用的化肥品种以碳酸氢铵、尿素磷酸二铵和各种复混肥为主;农药以各种高毒、高残留杀虫剂为主,如敌敌畏、对硫磷等。其中2003年的化肥单位耕地面积施用量1233.93kg·hm-2,纯N施用量718.96kg·hm-2,农药(商品量)12.39kg·hm-2,粮食产量14690.40kg·hm-2,分别比1996年增长了44.87%、16.15%、63.24%、3.89%。经分析,桓台县目前化肥、农药投入水平过高,化肥对粮食的增产效应已经不显著,且投肥结构不合理,N用量过高,P2O5投入较为合理,K2O用量严重不足。化肥、农药的过量施用对环境存在着严重的潜在威胁。

摘  要：
Chemical fertilizer and pesticide inputs in winter wheat-summer maize system in 1996 and 2003 in Huantai County were surveyed in July 1997 and May 2004 respectively. Ammonium carbonate, urea, ammonium hydrogen phosphate and compound fertilizers with different nutrient contents, and highly noxious insecticides such as omethoate, monocrotophos and parathion were mainly used in Huantai. In 1996, the application rates of chemical fertilizer (nutrients), N and pesticide (commodity) were 851.74 kg·hm-2, 618.99 kg·hm-2 and 7.59 kg·hm-2 respectively, while in 2003, they were 1 233.93 kg·hm-2, 718.96 kg·hm-2 and 12.39 kg·hm-2 respectively. The chemical fertilizer was misused, the produce efficiency of chemical fertilizer was not significant yet, and the ratio of N: P2O5: K2O was not reasonable, among which N was excessively used, P2O5 was irrationally used, but K2O was in great shortage. The misuse of agrochemicals resulted in the pollution of the rural environment to some extent, so some strategies were suggested based on the above analyses.
