5.Conclusions
Mulberry
and alfalfa showed a strategic complementarity in the use of six types
of carbon sources. Intercropping and nitrogen application changed the pH
value and the soil water content both in mulberry and alfalfa
rhizosphere soil and resulted in changes in the microbial community and
in microbial growth, leading to different carbon use patterns and
capability. There is mostly similar in rhizoshere soil microbial
communities structure and function between mulberry intercropped with
alfalfa without nitrogen application and mulberry monoculture with
nitrogen application.
