Abstract: The study aim to explore the effect of inoculated F. mosseae on the content of isoflaone and fatty acid. in order to provide the theoretical evidence using F. mosseae to the continuous cropping. Three soybean cultivars KF16 (middle cultivar), HN44 (high-oil cultivar), HN48 (high-protein cultivar) were investigated. The soybean seeds use 0-year soil samples (CK), 1-year soil samples (L1) and 2-year soil samples (L2) planted in the pot with 12.5 kg dry soil sample and inoculated 200g F. mosseae into each pot. The accumulation of the mature soybean isoflavone and fatty acid was determined by ultraviolet spectrophotometry and gas chromatography. It showed that: the highest isoflavone content of KF16, HN44 and HN48 was L1, L2 and L2, respectively. And with the increase of continuous cropping, the fatty acid content of KF16, HN44 and HN48 is decreasing. Inoculated F. mosseae could increase the content of isoflavone and decrease the content of fatty acid.
