文摘

Roots of different species occupied the same soil volume in a zone of high influence. In the short-term, root intermingling resulted from fast-growing species colonization. In the long-term, aboveground dominant species also dominated belowground. The same soil volume is exploited by active roots of several species according to RGR. Species differ in root biomass accumulation under or close to the aboveground portion.
