Abstract
To investigate the effects of barley straw on microflora, acetylene reducing activity, enzyme activity and sugar in relation to nitrogen fixation in submerged soil. The obtained results were summarized as follow: Of the nitrogen fixing microorganisms, the number of Azotobactor tended to increase with the application of barley straw as the rice grew. The number of Clostridia were increased at the tillering stage of plant and decreased thereafter, and that of Blue-green algae tended to increase at the heading stage and to decrease thereafter. On the other hand, the number of Blue-green algae tended to increase by the application of barley straw. Acetylene reducing activity was decreased in the heading stage and increased in the harvesting stage. There was no difference of acetylene reducing activity between the application of barley straw and control. In submerged soil treated with barley straw, enzyme activity of
