Root rot incidence index in potted-experiments of continuously cropped soybeans. Squares, circles, and triangles represent samples from the CK, F, and AF groups, respectively. CK means soybean were planted the normal sterilized soil; F means soybean seeds were inoculated with F. oxysporum spore suspension; AF means soybean seeds were inoculated with F. mosseae + F. oxysporum. Note: All experiments were conducted in potted-experiments. X-axis represents which day detected the root rot incidence index of soybean. Y-axis represents the root rot incidence index
