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 。 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.
