| 摘 要： | 长期定位试验研究松嫩平原典型中厚黑土区水稳性团聚体组成和微粒有机质积累分布规律结果表明,不同培肥模式和耕作制度对水稳性团聚体组成有很大影响,耕地团聚体组成以<1mm水稳性团聚体占绝对优势;微粒有机碳(POM C)主要存在于水稳性大团聚体中,且其含量随粒级减小而下降,这对维持耕地黑土大团聚体(>0 .2 5mm)水稳定性起重要作用

| Abstract: | Rule of accumulation and distribution of particulate organic matter and formation of water stable aggregates were studied by long term located experiments in the typical black soil region of Songnen Plain.The results show that there are great effects of different fertilization patterns and cultivation systems on the formation of water stable aggregates.<1mm water stable aggregates is the dominance in fraction of water stable aggregates from cultivated land.Particulate organic C exists mostly in the water stable macro aggregates,its content decreases with the decrease of particulate levels,indicating that particulate organic C plays an importent role in maintaining the water stability of aggregates in cultivated black soil. |
