近几年来我国各地有关科研单位研制和施用氮肥增效剂又称硝化抑制剂,使土壤中铵态氮转变成硝态氮的过程受到抑制,从而减少氮肥的损失,提高氮肥的利用率而达到作物增产效果。为了进一步了解氮肥增效剂对人畜有无毒害,以及对环境的污染,为安全合理使用和研制氮肥增效剂提供科学依据,我们进行了氮 In recent years, relevant scientific research institutes around our country have developed and applied nitrogen synergist, also known as nitrification inhibitor, which inhibits the process of converting ammonium nitrogen into nitrate nitrogen in the soil, thereby reducing the loss of nitrogen fertilizer and increasing the utilization rate of nitrogen fertilizer Crop yield increase effect. In order to further understand the non-toxic nitrogen fertilizer synergist on humans and animals, as well as environmental pollution, in order to provide a scientific basis for safe and rational use and development of nitrogen fertilizer synergist, we conducted a nitrogen
