据报道,山西省农业科学院土壤肥料研究所1963—1964年进行大豆接种根瘤菌效果的试验,结果证明,不同的大豆品种接种根瘤菌的自然感染率存所差异,因此不同品种接种根瘤菌的效果也不同,而且,不同品种之间对菌种有一定的适应性,用同一品种的大豆梗瘤菌接种于同一品种的大豆,增产效果最好。据观察,接种根瘤菌的 According to reports, Shanxi Academy of Agricultural Sciences Soil and Fertilizer Institute 1963-1964 soybean inoculation effect of rhizobia test results show that different soybean varieties inoculated with Rhizobia natural infection rate differences exist, so the effect of different varieties inoculated rhizobia Different, and different species have some adaptability to the strain, with the same species of soybean Stems inoculated in the same species of soybean, the best yield. It is observed that inoculation rhizobia
