氨氧化木质素作为硝化抑制剂的研究
Study on Ammoxidized Lignin Used as Nitrification Inhibitor
【摘要】 通过室内培养实验对氨氧化木质素(AOL)的硝化抑制作用进行了探讨。在相同条件下,分别加AOL和DCD处理的铵态氮质量分数都要比未加硝化抑制剂处理的高;相应地,在开始阶段硝态氮质量分数也要比未加硝化抑制剂处理的低。研究结果表明,AOL作为硝化抑制剂是有效果的。
【Abstract】 The effect of ammoxidized lignin (AOL) used as nitrification inhibitor was studied by house culture. In the end the ammonium nitrogen content of the treatment with AOL or DCD was towered above the one without those nitrification inhibitors, and the nitrate nitrogen content of the former was less than the latter. The result of the experiment indicated that AOL could be used as nitrification inhibitor. But AOL did not seem to be as good as DCD as a whole.
