摘要：

A field experiment was conducted to observe the influence of a cover crop (winter wheat, Triticum aestivum L.), and a perennial weed (dandelion, Taraxacum officinale Weber ex Wi,og.), on vesicular-arbuscular mycorrhiza (VAM) inoculum potential, soil aggregation and maize yield after one season. Mycorrhizal colonization of maize roots was higher following the autumn planting of either winter wheat or dandelion compared with fallow. In the dandelion plots maize had significantly higher P content, shoot dry weight and yield relative to the winter wheat plots. Winter wheat and dandelion both improved soil aggregation.
