| 摘 要： | 对枫香与杉木、马尾松混交后土壤有机质碳和腐殖质碳的变化进行研究表明:枫香与杉木、马尾松混交后,增加了土壤的有机质碳和腐殖质碳的储量,0~20 cm土层增加的幅度大于20~40 cm土层。从腐殖质的组成来看,混交林土壤无论是胡敏酸、富啡酸还是土壤腐殖化度都大于纯林,混交林土壤胡敏酸与富啡酸比值(HA/FA)也大于纯林。从而表明了混交林土壤腐殖物质的品质变佳,土壤熟化度增大,土壤供肥保肥的能力增强,土壤肥力得以提高。

| Abstract: | The study of soil organic and humic C in mixed plantations mixed plantations of Liquidambar formosana and Cunninghamia lanceolata,L.formosana and Pinus massoniana showed that mixed forests increased the soil organic C and humic C;in humic substances compositions,the contents of humic acid and fulvic acid in mixed forest soils are more than those in pure forest soils;the humification degree and HA/FA ratio in mixed forest soils are greater than those in pure forest soils.These results indicate that the quality of soil humic substances became better,soil maturity raised,soil nutrition-providing and nutrition-holding capacities increased and soil fertility improved in the mixed forests. |
