Nitrogenase activity was determined in situ by repeated assays at regular intervals to compare the patterns of diurnal variations occurring in a rice field, a grassland, and a peanut field. In the rice field only one peak occurred (mid-day), whereas the other systems exhibited typical two-peak patterns, which were suspected to be induced by climatic conditions or possibly by a specific rhythm of exudation. Observed data on diurnal variations in nitrogenase activity were fitted to different models of diurnal variation comprised of computed periodic curves.
通过定期重复测定原位测定固氮酶活性，以比较稻田、草地和花生田中昼夜变化模式。在稻田中仅出现一个峰值（中午），而其他系统呈现典型的双峰模式，怀疑这是由气候条件或可能由特定的渗出节律引起的。将观察到的固氮酶活性昼夜变化数据拟合为由计算出的周期曲线组成的不同昼夜变化模型。
