快生型大豆根瘤菌是我国特有的一类生物新资源。它是1982年由美国的Keyser和中国农科院土肥所胡济生共同发现的,它生长速度快、耐盐,与我国栽培大豆选择地共生。与相适应的栽培大豆共生时,大豆植株的干物质和旦白质含量比不接菌对照明显增加,大田小区试验增产效果在20％左右。 1.快生型大豆根瘤菌的田间试验(跃进五号大豆)。 2.快生型大豆根瘤菌的菌落形态。(左)慢生型大豆根瘤菌(菌落直径
Fast-growing soybean Rhizobium is a unique biological resources of our country. It was discovered in 1982 by Keyser of the United States and Hu Jisheng of the Institute of Soil Science and Technology of China Academy of Agricultural Sciences. It grows fast, salt-tolerates and is symbiotic with cultivated soybean in our country. When co-growing with the corresponding cultivated soybean, the dry matter and protein content of soybean plants increased significantly compared with the non-inoculated control, and the yield increase effect of the field plot test was about 20%. 1.
