紫云英根瘤菌已有二十多年的应用历史。随着农业微生物工作的发展,我省地、县、社已有几十个单位能够就地生产根瘤菌剂,满足供应。为了进一步提高根瘤菌的效果,给有关厂坊提供更好的生产菌株,我们于一九六七年开展了紫云英根瘤菌的分离筛选工作,从中得到具有粉红色标志的“红11”菌株。这个新菌株多年来已在省内各地应用。现将此菌株分离与性能测定结果整理于下:
Ziyungen rhizobia has more than 20 years of application history. With the development of the work of agricultural microorganisms, there are dozens of units in our province, prefecture, and county that can produce Rhizobium on-site to meet the supply. In order to further improve the effect of rhizobia and to provide better plant strains to the factories concerned, we conducted a screening and screening work on Rhizobium japonicum in 1967 and obtained the “red 11” strain with the pink mark . This new strain has been used throughout the province for many years. Now this strain isolation and performance measurement results are summarized in the next:
