摘要:

以开割橡胶无性系PR107为研究对象,研究1,6,11,16,21,26,31 a不同林龄胶园土壤有机碳、土壤微生物量碳、土壤矿化碳含量以及土壤碳有效率的垂直变化及其相关关系。结果表明:土壤有机碳(SOC)、矿化碳(CM)以及微生物量碳(MBC)含量在土壤剖面中的含量变化呈现相似的规律性,表现为随着土层深度的增加而碳含量下降,但不同林龄在不同土层的碳含量差异表现有所不同。不同林龄胶园土壤矿化碳有效率在4.15%~8.39%之间;土壤微生物量碳有效率在1.24%~7.55%之间。土壤有机碳和矿化碳以及微生物量碳均表现为线性正相关。

Abstract:

The objective of this study was to investigate the vertical distribution of soil carbon and correlations of rubber trees of 1a、6a、11a,16a,21a,26a,31a-old of strain PR107. The results showed that in the vertical distribution,monthly mean soil organic carbon(SOC)and mineralized carbon(CM)and microbial biomass carbon(MBC)content in soil showed similar regularity and decreased with the increase of soil depth,but the carbon content in different soil layers,different ages have different performance.The soil mineralization carbon efficiency of rubber plantation is about 4.15%~8.39%;and the efficiency of soil microbial biomass carbon is between 1.24%~7.55%.There was a significant linear positive correlation with soil organic carbon and mineralized carbon and with the microbial biomass carbon.

Key words: rubber tree(Heveabrassiliensis), carbon content, effective rate
