Abstract
This study was conducted to examine the distribution of soil N:P ratios and its regulating factors based on soil properties (bulk density, water content, organic carbon content, and pHH2O) and stand factors (tree diameter at breast height and height, stand density, canopy closure, understory and litter biomass) from different ages of P. kesiya plantations (5, 11, 15, 25, and 35 years old) in Bao Lam Forestry Company, Lam Dong Province. The results showed that: (1) Soil N:P ratios at different soil depths decreased significantly with plantation age. Soil N:P ratios decreased significantly with increasing soil depth, and the highest N:P ratios were in the top 0–20 cm of soil. (2) Soil N:P ratios in P. kesiya forests were mainly explained by soil feature factors (bulk density and water content). (3) Stand feature factors (tree diameter at breast height and height, stand density, canopy closure, understory and litter biomass) also played an important role in contributing to the soil N:P ratio in P. kesiya forests. The results of this study contribute to a deeper understanding of the biogeochemical cycles and equilibrium mechanisms of N and P in soils.
Tóm tắt
Nghiên cứu này được thực hiện nhằm kiểm tra sự phân bố tỷ lệ N:P trong đất và các yếu tố điều chỉnh của nó dựa trên các yếu tố đất(dung trọng,hàm lượng nước,hàm lượng carbon hữu cơ và pHH2O) và lâm phần(đường kính ngang ngực,chiều cao vút ngọn,mật độ,độ tàn che,sinh khối cây tầng thấp và vật rơi rụng) từ các tuổi khác nhau của rừng trồng Thông ba lá (5, 11, 15, 25 và 35 năm tuổi) tại Công ty Lâm nghiệp Bảo Lâm, tỉnh Lâm Đồng.Kết quả cho thấy: (1) Tỷ lệ N:P trong đất ở các độ sâu tầng đất khác nhau giảm đáng kể theo tuổi rừng trồng; Tỷ lệ N:P trong đất giảm đáng kể khi độ sâu tầng đất tăng và tỷ lệ N:P cao nhất nằm ở độ sâu 0 - 20 cm trên cùng của đất; (2)Tỷ lệ N:P trong đất ở rừng Thông ba lá chủ yếu được giải thích bằng các yếu tố đặc điểm đất (dung trọng và hàm lượng nước);(3) Các yếu tố đặc điểm lâm phần (đường kính ngang ngực,chiều cao vút ngọn,mật độ,độ tàn che,sinh khối cây tầng thấp và vật rơi rụng)cũng đóng vai trò quan trọng trong việc đóng góp tỷ lệ N:P của đất ở rừng Thông ba lá. ết quả của nghiên cứu này góp phần vào sự hiểu biết sâu sắc hơn về các chu trình sinh địa hóa và cơ chế cân bằng của N và P trong đất.
