Abstract:
The soil fertility and the water conserving capacity of the 35-year-old
Cyclobalanopsis chungii and
Cunninghamia lanceolata plantations were studied by investigating into the biomass and soil fertility of these plantations.The results showed that the
Cyclobalanopsis chungii plantation had better function to improve water conserving capacity and soil fertility compared with the
Cunninghamia lanceolata plantation.The steadiness of soil aggregate and porosity were promoted, the bulk density was decreased, and the water and nutrient conditions in the
Cyclobalanopsis chungii plantation were better than those of in
Cunninghamia lanceolata plantation.The water holding rate of
Cyclobalanopsis chungii leaves was 1.17 times that of
Cunninghamia lanceolata leaves.Conclusively speaking, the function of improving the water conserving capacity and soil fertility of
Cyclobalanopsis chungii plantation was better than that of
Cunninghamia lanceolata plantation.
