用高效紫云英根瘤菌接种,是保证紫云英种植成功和高产的途径。为了寻找更高效能的菌株,福建省农科院土肥所微生物室和福建省光泽县农药厂进行了紫云英根瘤菌的分离筛选工作,从中得到具有粉红色的菌株——“红11”菌株。“红11”菌株,具有不同于其他根瘤菌的特征,菌落(或菌苔)呈粉红色;菌体为椭园或卵园形杆状菌,一般大小为宽0.51μ—0.55μ,长 Vaccination with high-efficient Rhizobium japonicum is the way to ensure the success and high yield of Astragalus cultivation. In order to find a more efficient strain, the Fujian Provincial Academy of Agricultural Sciences Department of Soil and Fertilizer Microbiology Department of Guangze County, Fujian Province pesticide plant Rhizobium isolated from the Rhizobium screening work, from which a pink strain - “Red 11” strain . “Red 11” strain has different characteristics from other rhizobia, the colony (or lawn) is pink; the cell body is oval or oval-shaped bacilli, the general size is 0.51μ-0.55μ wide, long
