摘　　要：分别从湖北、湖南等６个省的５种土壤、１３个大豆品种（次）分离、鉴定出８００多株快（Ｒｈｉｚｏｂｉｕｍｆｒｅｄｉｉ）、慢（Ｂｒａｄｙｒｈｉｚｏｂｉｕｍｊａｐｏｎｉｃｕｍ）生大豆根瘤菌。快生根瘤菌在其中的４个地区出现，分离频率为０～５６．５％。我国土壤中的快生大豆根瘤菌主要是ＵＳＤＡ２ｌ７、２０４８、ＤＥ１６１１、２ｌ２０、２０７７等血清型。６个大豆栽培地区都分离到慢生大豆根瘤菌，１１３－２／Ｃ２２４／００５、ＵＳＤＡ１１０、ＬＬ１２０、００５、Ｃ２２４血清型菌株是优势的群体。此项研究为大豆根瘤菌剂的田间应用和大豆遗传育种提供了科学依据和实验材料。About 800 fast-growing and slow-growing soybean rhizobia obtained from 6 soybean production regions have been identified. Fast-growing strains presented in 4 sites of 6 sampled regions with different isolating rates(0～56.5%).USDA2l7,2048,DE1611 and 2077 were dominant serotypes in Chinese soil.Slow-growing strains were isolated in all the sampled nodules and soils,and strains in serotypes 113-2/C224/005,USDA110,LL120 and 005 are dominant rhizobium populations.This study will contribute to better discovering and using natural resources of soybean rhizobium and genetic breeding of soybean.
