| 摘 要： | 以农业部哈尔滨黑土生态环境重点野外科学观测试验站长期定位试验为平台，研究了长期施肥对黑土水溶性碳（WSOC）和矿化碳的影响。结果表明，施肥对土壤WSOC的含量有很大影响，比较而言，单施化肥对WSOC含量无明显影响，而施加有机肥可使黑土WSOC含量增加。土壤对水溶性有机碳的吸附量与平衡前水溶性有机碳的浓度显著相关。有机肥与无机肥料配施可以提高土壤矿化碳含量。

| Abstract: | Long-term fertilization trial was conducted to study the effect of various fertilizer application on water-soluble organic carbon (WSOC) and organic carbon mineralization at Key Observation Station of the Harbin Black Soil Ecology, Ministry of Agriculture. The results showed that fertilization had various effects on soil WSOC. Only chemical fertilizer application had no significant impact on soil WSOC concentration, however, applying organic fertilizer can increase the concentration of WSOC. Mollisol can absorb WSOC and significantly correlated with WSOC concentration. Organic and inorganic fertilizers combined application can increase the carbon content. |
