由辽宁省搜集的野生大豆根瘤中筛选出一批新菌种。经室内鉴定和盆栽试验,初步认为其中有些菌种对大豆共生效应较强。为了及早应用于生产,于1984年在铁岭市农科所设区试验,于1985~1987年在昌图、新宾等县,进行多点试验。土壤种类为黑黄土、砂壤土、棕黄土,肥力中等,前茬为玉米、谷子、白菜。现将三年试验总结如下。一、试验材料 (1)菌种与菌剂:2057、2053、 A batch of new species was screened from the wild soybean nodules collected in Liaoning Province. After indoor identification and pot experiment, it is preliminarily believed that some of the strains have a strong symbiotic effect on soybean. In order to be applied to the production as early as possible, it was tested in the area set up by the Agricultural Science Institute of Tieling City in 1984 and many experiments were conducted in Changtu and Xinbin from 1985 to 1987. Soil types of black loess, sandy loam, brown loess, medium fertility, the former crop of corn, millet, cabbage. The three-year trial is summarized as follows. First, the test materials (1) strains and fungi: 2057,2053,
