摘要

为探知红松苗对未来大气CO₂浓度的碳、氮响应策略,系统了解不同CO₂浓度下红松幼苗及其土壤碳、氮特征,采用生长箱培养法,分别研究了350、700 μmol/mol CO₂浓度下红松幼苗主要器官碳、氮浓度与积累(吸收)量变化,并分析其培养土壤的碳、氮含量。结果表明:与低浓度CO₂处理相比,高浓度CO₂处理并未对红松幼苗根、茎及叶的碳浓度产生显著影响,但导致叶碳积累量显著增加37.63%; 高浓度CO₂培养导致红松幼苗根、茎、叶氮浓度显著降低,茎氮吸收量显著下降27.45%,根、茎、叶的碳氮比升高,土壤溶解性有机碳含量显著增加28.82%,总有机碳、微生物量碳、全氮、微生物量氮及水解性氮含量均未发生显著变化,碳氮比增加。总体上,3年生的红松幼苗氮浓度、碳氮比、叶碳积累量及土壤溶解性有机碳对CO₂升高响应迅速。

Abstract

Carbon and nitrogen characteristics of Pinus koraiensis seedling and its soil under different CO₂ concentrations were investigated to explore the response strategies of P. koraiensis and their habitats to higher CO₂ concentration conditions. Based on growth chamber method, the concentration and accumulation of carbon and nitrogen in P. koraiensis seedling organs and its soil were measured and compared under environmental CO₂ concentration of 350 μmol/mol and 700 μmol/mol, respectively. Comparing to lower CO₂ concentration of 350 μmol/mol after a growth season, the results showed that: ① No significant difference of carbon concentration was detected in root, stem and leaf of P. koraiensis seedling by CO₂ treatments, however carbon accumulation of the leaf increased by 37.63% when CO₂ concentration increased to 700 μmol/mol. ② Nitrogen concentration of root, stem and leaf decreased significantly at higher CO₂ concentration, and the stem nitrogen accumulation to CO₂ enrichment declined by 27.45%. ③ C/N ratio of root, stem and leaf to CO₂ enrichment increased significantly. ④ Concentration of soil extractable dissolved organic carbon increased significantly by 28.82% at higher CO₂ condition, the concentration of soil organic carbon, microbial biomass carbon, soil total nitrogen, microbial biomass nitrogen and hydrolysable nitrogen did not change significantly between CO₂ treatments, and soil C/N ratio to CO₂ enrichment varied with a small increasement. Overall, nitrogen concentration, C/N ratio, leaf carbon accumulation of P. koraiensis seedling and soil extractable dissolved organic carbon responded quickly to higher CO₂concentration during this period.
