The dynamics of nitrogen fixation was studied in the phyllosphere of birch and timothy, and the productivity of the process within the vegetation period was determined on the basis of the study. The activity of nitrogen fixation was measured under natural conditions using the acetylene technique. A proportion is suggested which makes it possible to determine the actual activity of nitrogen fixation in the phyllosphere from the potential one. The productivity of nitrogen fixation was 7 and 10 kg of nitrogen per hectare per season for birch and timothy respectively.
研究了白桦和梯牧草叶际中固氮作用的动态，并在此研究基础上确定了植被期内该过程的生产力。在自然条件下使用乙炔技术测量固氮活性。提出了一个比例，通过该比例可以从潜在固氮活性确定叶际中实际的固氮活性。白桦和梯牧草的固氮生产力分别为每公顷每季节7千克和10千克氮。
