3.2 | Comparison ofrhizosphere soil properties
Table 2 shows that there were no significant differences in pH, total
nitrogen content or C/N among the three families. The
total organic carbon content and
soil moisture in the samples increased with increasing carbon
sequestration, and the differences among the three families were
significant (P<0.05). In terms of altitude, the mean values of
families No. 4 and No. 64 were significantly higher than that of No. 66.
Combining these data with those in Table 1, we speculated that the
growth and carbon sequestration capacity of samples were directly
proportional to their soil moisture and total organic carbon but
inversely proportional to their altitude.
