Abstract

Dinitrogen fixation activity was determined directly on experimental plots in mixtures of grass with red and white clover in the year of sowing as well as in the first year of full utilisation using the method of acetylene reduction (ARA). Furthermore, numbers of bacteria, actinomycetes, fungi and Azotobacter sp. were determined in soils under the experimental mixtures.

三叶草-草混合植物的生物固氮活性。
采用乙炔还原法(ARA)直接测定了红白三叶草混合草在播种年和充分利用第一年的固氮活性。此外,还测定了试验混合物下土壤中细菌、放线菌、真菌和固氮细菌的数量。
