2008年1月 磷肥 与 复肥 第23卷第1期 Phosphate Compound Fertilizer ◆论 坛◆ 再议 “我国复混肥行业现状及发展机遇’’ 许秀成 (1．郑州大学 化工学院，河南 郑州 450001；2．《磷肥与复肥》编辑部，河南 郑州 450001) [摘 要]2006年我国化肥实物产量约为1．6亿t，全国化肥平均养分约为33％，单纯追求化肥养分含量高，不 利于资源合理利用。我国复合肥产能已超3亿t，实物产量约为5 000万t，产能利用率低。着重讨论了功能性肥料 的开发，生产中、低浓度肥料的必要性，比较了我国复合肥行业与国外的差距。 [关键词]复合肥料；工厂生产能力；功能性肥料；低浓度肥料；合理利用资源 [中图分类号]TQ444 [文献标识码]A [文章编号]1007—6220(2008)01—0001—05 Further discussion on the present status and development opportunity of compound fertilizer industry in China XU Xiu-cheng。 (1．School of Chemical Engineering，Zhengzhou University，Zhengzhou，Henan 450001，China； 2．Editorial Department of PhosphateCompound Fertilizer，Zhengzhou，Henan 450001，China) Abstract：In 2006 the output of chemical fertilizer products is approximately 1 60 million tons in China， with the average nutrients of 33％ ．Simply pursuing the high analysis chemical fertilizer is considered disadvantage0us to the reasonable use of the resource．The productivity of compound fertilizer in China iS over 300 million tons，however，the actual output is approximately 50 million tons．The ratio between the actual output and the productivity is very low．The development of functional fertilizer and the necessity of low analysis chemical fertilizers in production are emphatically discussed．The gap between domestic compound fertilizer industry and overseas one is also analyzed． Key words：compound fertihzer；plant productivity；functional fertilizer；low analysis fertilizer；reasonable use of n Snl】rce 作为《磷肥与复肥》主编，经常被问及我国复 表1 我国各种氮肥实物产量估计值 万t 合(混)肥料现状如何?有何发展机会?由于我国 地域辽阔，复合(混)肥厂多得难以统计。在各方 友人的帮助下，曾推算了2005年国产化肥养分平 注： 根据中国氮肥工业协会提供的折纯产量推算，不包括磷复肥 均含量、复合(混)肥厂生产能力及产量，
