Fine root and grass root decomposition and nutrient dynamics in an intercropping system of Alnus formosana-Lolium multiflorum

On the basis of the research of the fine root of the Betula luminifera-Hemarthria compressa compound mode and grass root biomass in Hongya county,Sichuan province,we discuss the underground spatial distribution pattern of this mode.

This study aims to investigate the rate of mass loss and release of nutrient elements of fine root and grass root in plantation of Triploid Populus tomentosa and Lolium multiflorum established on an abandoned farmland at Tianquan County in Sichuan Province.
