Abstract
The effects of arbuscular mycorrhizal fungi(AMF) community,which was collected from a long-term fertilization field in Fengqiu,Henan Province,on the growth of white clover (Trifolium repens) at different N levels were studied using Fengqiu soil as substrate.The results showed that root colonization decreased with the increase of three N supply levels.The AMF community collected from NK soil (nitrogen and potassium chemical fertilizers) improved the growth and nutrient uptake of white clover at three N supply levels.However,at high N levels,the AMF community collected from 1/2 OM+ 1/2 NPK soil(1/2 organic matters+ 1/2 nitrogen,phosphorus,and potassium chemical fertilizers) had no help to nutrient uptake,but inhibited the growth of white clover.It suggests that different regimes of longterm fertilization change the structure of AMF community,and thus have different effects on the growth and nutrient uptake of white clover.

Claim · model-written summary
The authors inferred that long-term fertilization regimes change AMF community structure and thus their effects on white clover.
