    Effects of Tillage Methods on Scattered-Transplanting Rice Growth and Nitrogen Use Efficiency

      摘要
    • 摘要: 利用盆栽试验和^15N示踪技术研究了不同耕作方法对抛秧水稻生长和氮肥利用率的影响。结果表明，免耕抛秧水稻产量比传统耕减少32．6％，氮肥利用率降低15．6％，然而，轻耕和传统耕水稻产量和氮肥利用率相近。

       

      Abstract: Effects of different tillage methods on rice growth and nitrogen use efficiency were studied in a potted experiment using 15 N. The results showed that compared with the conventional tillage, with scattered transplanting, the rice yield decreased by 32.6% and nitrogen use efficiency decreased by 15.6% in no tillage. However, minimum tillage and conventional tillage had the similar rice yield and nitrogen use efficiency.
