从1980-1985年对新疆全境进行根瘤资源调查,采集与分类研究。共采集根瘤标本220份,包括37属、120种豆科植物,其中50个种是新发现其结瘤情况的;分离出100多株抗逆性强的、与多种重要豆科植物共生固氮的根瘤菌和,经数值分类,新疆的快生型根瘤菌分別属于已知Rhizobium的各个种,不过其离散性较大;而新疆慢生型根瘤菌的很多特性完全不同于已知慢生根瘤菌必Bradyrhizobium,用多种方法聚类,确定为一新的分类单元、拟建议为Rhizobium中的一个新种、筛选出的大豆、苜蓿根瘤菌在新疆地区接种,大豆增产10%以上,苜蓿增产20%。
From 1980 to 1985, we conducted a survey of nodulation resources, collection and classification of the entire territory of Xinjiang. Totally 220 specimens of nodules were collected, including 37 genera and 120 leguminous species, of which 50 species were newly found to be nodulated. More than 100 strains with strong stress resistance and symbiotic nitrogen fixation with many important leguminous plants were isolated Of rhizobia and, by numerical classification, Xinjiang quick-release rhizobia belong to all species known Rhizobium, but its discreteness is larger; and Xinjiang slow-growth rhizobia many features completely different from the known slow-root nodules Bacillus thuringiensis Bradyrhizobium, clustered by a variety of methods, identified as a new taxon, proposed to be a new species in Rhizobium, screening of soybean, alfalfa inoculation in Xinjiang region, soybean yield increased more than 10%, alfalfa yield 20%.
