Data are means with the standard errors (n=4) except for shoot biomass
where n=8. Significant differences among three planting densities at
each plant growth stages are denoted by different letters (post hoc
Tukey–Kramer honest test, p < 0.05).
Table 2: Gross nitrification (GNN), total dissolved organic C (DOC) and
dissolved N (DN), microbial biomass C (MBC) and N (MBN), mineral N
(exchangeable NH4+ plus
NO3-), C: N ratio of SOM
mineralization (SOM-derived CO2: GNM), the DOC: DN ratio
and the MBC: MBN ratio for each level of the planting density at
different plant growth stages.
