摘要
本文报导了对新型氮污染抑制剂CQS（CompositeQuinonidSubstances）功能的研究结果。该合成物质在试验条件下对尿素的水解有抑制作用．对硝化作用更有强烈的抑制作用，同时能提高植物体内叶绿素含量和改进生长，从而能提高植物体内对氮，磷，钾等养料的吸收力。在试验条件下，一般化学氮肥利用率提高30％以上，在不同土壤上有5％～30％的增产效果。
A new material named CQS was proposed out in this paper, used as an ammonification and nitrification ixthibitor. Experiments showed that the inhibitory effect may be nearly 70% under favorable conditions. The investigation of numerous works emphasibo that this material has also been given to providing a favorable infiuence for the growth of crops.
