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.
