| 摘 要： | 利用网袋模拟秸秆还田方式,研究不同还田方式不同阶段玉米秸秆氮、磷、钾养分释放特征。结果表明,经过150 d的分解,玉米秸秆生物量38.9%～66.3%被分解,埋于土壤的玉米秸秆分解速度明显高于露天处理。腐解后玉米秸秆从组织结构上变得松散。经150 d腐解后,玉米秸秆的氮、磷、钾养分释放率分别为51.1%～67.7%、76.0%～89.8%、76.9%～91.7%。

| Abstract: | Net bag method was used to determine nutrition decomposing characteristics of N,P,and K of maize strawunder two different crop straws returning approaches.The results showed that after 150 days,the decomposition rates of maize straws of different treatments were between 38.9%-66.3%.The trend of straw decomposition of soil coverage treatment was higher than open-air treatment.Tissue of maize straws became loose after decomposing.The decomposition rates of N,P and K were 51.1%-67.7%,76.0%-89.8% and 76.9%-91.7%,respectively. |
