| 摘 要： | 为了明确稻草还田方式对双季稻田土壤肥力的影响，对不同稻草还田方式对土壤总有机碳(CTOC)、活性有机碳(CA)、矿化碳(CM)的影响进行分析，并计算了各处理碳库活度(A)、碳库活度指数(AI)、碳库指数(CPI)和碳库管理指数(CPMI)。结果表明，与不施肥对照相比，早晚稻两季稻草还田提高了土壤总有机碳、活性有机碳和矿化碳含量及其碳素有效率。等养分条件下，稻草还田处理的土壤总有机碳、活性有机碳及其碳素有效率均高于稻草烧灰还田和稻草不还田处理，且活性有机碳含量差异显著。土壤碳库管理指数处理间差异达显著或极显著，其大小趋势为稻草全量还田 > 稻草烧灰还田 > 稻草不还田。 |

| Abstract: | In order to understand the effects of different models of straw returning to field on soil fertility of double-harvest rice field,the TOC(total organic carbon) ,AC(active carbon) pool and M(mineralized carbon) were analyzed,and A(carbon pool active) ,AI(carbon pool active index) ,CPI(carbon pool index) and CPMI(carbon pool management index) were calculated.The results indicated that comparing with the not applied fertilizer treatment(CK) ,C_(TOC) ,C_A,C_M and the available ratio of soil carbon were increase... |
