用大豆根瘤菌拌种是提高大豆产量的有效措施之一。本试验是为了鉴定在多熟制中应用大豆根瘤菌的效果。1976、1977两年,湖北油料研究所和孝感县丰山大队农科所共同协作,在该大队14趴秋、春大豆上进行了不同菌株比较试验;同时,生产草炭根瘤菌剂约100斤,按1斤拌5亩大豆种子,在这个大队“油—稻—豆”、“肥—稻—豆”、“麦— Soybean rhizobium seed dressing is one of the effective measures to increase soybean yield. The purpose of this experiment was to identify the effect of soybean rhizobia in a multi-cooked system. 1976, 1977, two years, Hubei Oil Research Institute and Xiaogan County Fengshan Brigade Agricultural Cooperatives work together in the brigade 14 lying autumn, spring soybeans were tested on different strains; the same time, the production of about 500 pounds of grass charcoal rhizobial agent, Press 1 kg mixed with 5 acres of soybean seeds, in this brigade “oil - rice - beans”, “fat - rice - beans”, "wheat -
