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。

关 键 词:抛秧稻  产量  氮肥利用率  耕作方法  示踪技术  氮15  生长

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.
Keywords:scattered  transplanting rice  yield  nitrogen use efficiency  tillage methods  15  N trace
