| 摘 要： | 为阐明免耕土壤碳转化过程对土壤同碳的影响,设计了4种耕作方式,包括稻草还田免耕(NTS)、稻草还田常耕(CTS)、无稻草还田免耕(NT)和无稻草还田常耕(CT),在水稻生育期分层(0~5、5~12和12~20 cm)采集稻田耕层土壤样品进行测定.结果表明,在0~5 cm土层,土壤有机碳、活性碳、热水提取碳水化合物、全酚... |

| Abstract: | In order to elucidate the effect of conversion process of the soil organic carbon on carbon fixation,four tillage patterns including no-tillage with straw incorporated(NTS),conventional tillage with straw incorporated(CTS),no-tillage without straw incorporated(NT) and conventional tillage without straw incorporated(CT) were designed.Soil samples were collected in soil layers(0-5,5-12 and 12-20 cm) during rice growth period.The result showed that in 0-5 cm layer,the content of organic carbon,active carbon,ho... |
