摘　　要：采用"3414"田间肥效试验方案,在3个试验点进行烟后作稻田间试验,研究永定县烟后作稻的氮磷钾肥效和最挂施用量。试验结果表明:合理施用氮磷钾肥可有效提高烟后作稻的产量,烟后作稻施用适量氮磷钾肥即处理6,可分别增产20.3%、4.9%和9.0%。在试验条件下,烟后作稻的氮磷钾经济施肥量为N 1116kg/hm2、P2O531kg/hm2、K2O 81kg/hm2、预计产量7 926kg/hm2。3 test fields with＂3414＂ fertilizer test on rice after cultivated tobacco were researched, its aimed to study of NPK fertilizer efficient and best fertilizer rate on rice after cultivated tobacco in Yongding. The results showed that appropriate NPK fertilizer rate can increase the yield of rice after cultivated tobacco, the highest yield of rice is treatment 6, compared with other 3 fertilizer level its increased 20. 3 %, 4. 9 %, 9. 0% respectively. Its indicated that the reeomend fertilizer rate were N 1116 kg/ hm2, PzOs 31 kg/hm2, K2O81 kg/hm2, respectively, the yield was 7926kg/hm2 under the condiction of Yongding.
