本文根据用标记和非标记尿素进行的培养试验,论述了氢醌对于尿素的水解、氨的释出和挥发、硝化和反硝化作用以及生物固持的影响。得出的结论是:氢醌的作用不仅在于延缓尿素的水解和减少随之而来的氨的挥发,更重要的,是影响了尿素水解产物进一步转化的进程,增强了尿素氮对于作物的有效持续供应和减少了它的总损失。本文认为,在脲酶抑制剂的研究中,着眼点当不仅在于它们的直接作用,而更需要涉及对尿素氮转化的一系列过程的影响。这样,才能对抑制剂的作用机理有更深入的了解,对它的作用效果有更全面的评价。
Based on the culture experiments with labeled and unlabeled urea, the effects of hydroquinone on the hydrolysis of urea, ammonia release and volatilization, nitrification and denitrification, and biological retention were discussed. It is concluded that the role of hydroquinone is not only to retard the hydrolysis of urea and to reduce the ensuing ammonia volatilization but more importantly to affect the process of further conversion of urea hydrolysates and to increase the effectiveness of urea nitrogen in crops Continuous supply and reduce its total loss. This paper argues that in the study of urease inhibitors, the focus is not only on their direct effects, but more on the implications of a series of processes involving the conversion of urea nitrogen. In this way, we can have a deeper understanding of the mechanism of action of inhibitors and give a more comprehensive assessment of their effects.
