摘　　要：本文对从中国东北地区土壤中分离到的８株弗氏中华根瘤菌（Ｓｉｎｏｒｈｉｚｏｂｉｕｍｆｒｅｄｉｔ）进行了血清学和氢代谢研究。交叉凝集试验结果表明其中存在３种血清型，而Ｓｊ５与国内外目前发现的１４种Ｓ．ｆｒｅｄｉｉ接种的大豆依赖共生固氮作用，在其株木质部汁液中，含有大量的酰脲（尿囊酸＋尿囊素），它是共生固氮氮素贮存和运输的主要形式，与接种Ｂ．ｊａｐｏｎｉｃｕｍ的值株木质部汁液中的氮运输特征基本相同。而施以无机氮源的大豆植株，其木质部汁液中酰脲含量相对较低，但却含有相对多的氮基酸［１］。strains of Sinorhizobium fredii are studied on their serology and nitrogen metabolism. The cross agglutination suggests that there are 3 kinds of serology types, Sj5 is a very special one and does not react with any of the 14 other known serology types.There are ureide (allantoic acid+allantain) in the xylem sap of soybean plants inoculated with both B. japonicum and S. fredii. Uride is main nitrogen type of symbiont association. The nitrousal metabolism of these soybean plants depending on inorganic nitrogen fertilizer is quite different from that depending on symbiotic nitrogen fixation, relatively high amino acid content is found in their xylem sap.
