Abstract：To illuminate the best date of fertilizing Piriformospora indica into rape field, the yield increasing effect of Piriformospora indica on rape and its mechanisms were studied at different periods of rape (seedling, bud,flowering,pod stages). The results showed that Piriformospora indica could improve significantly the weight of rape roots at seedling stage of rape compared with CK ( no Piriformospora indica ) . Piriformospora indica could significantly increase the thousand grain weight and yield of rape per plant at flowering and pod stages. The output per plant increased 27. 43% and 27. 95% respectively at the two stages compared with CK. The fertilization of Piriformospora indica could improve the actual production at each period of rape, but fertilization at the pod stage was better than at other stages, with the actual production reaching 3 004. 65 kg/ha,increased by 37. 30% compared with CK,and the economic income increasing 2 448. 90 RMB/ha. The test results of related physiological indexes showed that Piriformospora indica could decrease the content of MDA and increase the activities of POD and SOD in rape,which indicated that Piriformospora indica might increase the resistance of rape,and promote rape yield enhancement.
