我们用中国农科院油料作物所的花生根溜菌菌株009作出发株,经20微克/毫升的吖啶橙处理后,从处理液中分离到1211个衍生菌株。然后采用改良的水培法,以本省良种芙蓉花生为寄主植物进行回接试验,从中筛选出305、4341、4464和4551等侵染、结瘤能力强的菌株,配组成良种花生一优良菌 We use the Chinese Academy of Agricultural Sciences Oil Crops peanut rhizobia strain 009 to make hair strain, after 20 micrograms / ml of acridine orange treatment, 1211 derived strains isolated from the treatment solution. Then, a modified hydroponics method was used to carry on the back-linking experiment with the host plant of the hibiscus peanut in our province to select the strains of infection, nodulation capable of 305, 4341, 4464 and 4551,
