对快生型大豆根瘤菌的形态特征、主要生理生化特性以及对碳源的利用等,我们曾作了初步研究.其中有些结果与国内外研究结果相近似.但对快生型大豆根瘤菌与我国栽培大豆的共生效应报导甚少,H·H·Keyser等人曾认为“快生型大豆根瘤菌仅可与野生大豆(Glyoine soja)和未经改良的大豆品种行有效共生,与美国栽培大豆品种共生时无效”.然而我们经连续三年试验,结果表明快生型大豆根瘤菌与我国相应的 We have made a preliminary study on the morphological characteristics, major physiological and biochemical characteristics and the utilization of carbon sources of fast-growing soybean rhizobia, some of which are similar to the results at home and abroad, The symbiotic effect of cultivated soybean in China has been poorly reported. H · Keyser et al. Once considered that “fast-growing soybean rhizobium can only symbiose with Glyoine soja and unmodified soybean effectively, Soybean varieties symbiotic invalid. ”However, we have been tested for three consecutive years, the results show that fast-growing soybean Rhizobium and our corresponding
