近年来，随着作物产量水平的不断提高，肥料用量特别是氮肥用量越来越多，肥料利用率和报酬率递减，并对环境产生一定的影响。众多的试验结果表明：由江苏农学院、镇江市农业局联合研制开发的集成型化肥增效剂（ＩＦＣ）对增加作物产量、提高肥料利用率有显著作用。本文主要讨 In recent years, with the continuous increase of crop yield, the amount of fertilizer, especially nitrogen fertilizer, is increasing, the fertilizer utilization rate and return rate decrease, and have a certain impact on the environment. Numerous experimental results show that the integrated fertilizer synergist (IFC) developed jointly by Jiangsu Agricultural College and Zhenjiang Municipal Bureau of Agriculture has a significant effect on increasing crop yield and increasing fertilizer utilization rate. This article mainly discuss
