摘要(Abstract)：

土壤中的全氮含量密切关乎粮食生产和食品安全。保护性耕作下秸秆还田和土壤扰动的减少会影响全氮在土壤中的分布,但有关保护性耕作对黑土土壤全氮含量的影响及其特征的研究却鲜有报道。本文通过长期田间定位试验,研究了免耕、垄作(秸秆还田条件下的少耕)和秋翻3种耕作方式下耕层土壤全氮含量的垂直分布和年际变化特征。结果表明:13年的免耕试验可显著提高表层(0~5 cm)土壤全氮含量,降低亚表层(5~10 cm)土壤全氮含量;垄作和秋翻都能够提高表层(0~5 cm)和亚表层(5~10 cm)土壤全氮含量,而秋翻的全氮增加量低于垄作。总体而言,3种耕作方式中,垄作更有利于土层中的氮的固存在,从而促进土壤全氮的积累,有望成为实现东北黑土降低氮肥施用的有效措施。
