摘要

对甘肃省白龙江流域甘南、陇南的大部分地区豆科植物——根瘤菌资源进行了调查

共采集21属45种豆科植物69份根瘤样品。从69份样品中获63株根瘤菌

对其中44株根瘤以13种寄主进行了回接试验

31株结瘤

结瘤率70.5%。该区根瘤一般带有粉红色

形态比较规则。乙炔还原活力测定结果表明

88.5%为有效根瘤。不同种根瘤固氮活性相差不大

但高于甘肃省其它地区。对豆科植物在蓄水保土

改良土壤状况中的地位进行了讨论。

Abstract

The total numbers of 69 root nodules which were collected dispersed over 21 genera

45 species of legumes according to our investigation of rhizobium resources of leguminous plant in Bailong river basin

Gansu province

63 strains of root nodule bacteria from 69 samples were isolated. Experiments on 44 stains among 31 were inoculated back to 13 species hosts. The shapes of nodules of these plants were circular

ellipse or cudgel with pick in color. The results of acetylene reduction detection showed that 88.5% were effective for nitrogen fixation. Activities of nitrogen fixation in nodules varied littlely and were higher than that in other areas of Gansu province.
