| 摘 要： | 以位于西南大学试验农场的紫色土长期免耕试验田为研究对象,探讨了不同耕作方式-冬水田平作(DP)、水旱轮作(SH)、垄作免耕(LM)、厢作免耕(XM)和垄作翻耕(LF)对紫色水稻土全氮及碱解氮的影响.结果表明,在0～60cm的土壤深度内,不同耕作方式下土壤全氮的含量为LM(1.53g/kg)＞DP(1.50g/kg)＞X...

| Abstract: | Soil total nitrogen and alkali-hydrolyzed nitrogen based on a long-term experiment with various tillage systems were studied in a purple paddy soil at the farm of Southwest University,Chongqing,China.The experiment included five tillage treatments: conventional tillage with rice only system(DP),conventional tillage with rotation of rice and rape system(SH),no-till and ridge culture with rotation of rice and rape system(LM),no-till and plain culture with rotation of rice and rape system(XM),and tillage and r... |
