Abstract
In order to study the mycorrhizal effects of mycorrhizal seedling after transplanting,three nitrogen(N) levels,45,67.5 and 90 kg/ha,were applied in field experiments and the effects of mycorrhizal seedlings on phosphorus(P) content in soil and N and P absorption of plants at fast growing stage were studied.The results showed that: 1) The effects of Arbuscular mycorrhizal(AM) fungus inoculating on the P content in tobacco planting soil and tobacco plants were insignificant at the N application level of 45 and 67.5 kg/ha,however,P content would be effectively improved at the level of 90 kg/ha.2) The N contents in tobacco root,stem and leaves were remarkably decreased by Glamus mosseae(Gm01)inoculating at different N application levels,but,Glamus mosseae(Gm02)inoculating was remarkable only at the application level of 90 kg/ha.3) The N/P ratio in tobacco was effectively decreased by AM fungus inoculating at different N levels,however,Glamus mosseae(Gm01)inoculation was more effective.It indicated that N application would affect the mycorrhizal effects of AM fungi,but the effects of Glamus mosseae from different origin differed to a certain extent.
