摘　　要：2010年在岳阳县筻口镇对岳优9113进行了不同氮、钾施用量的试验,以探索该品种氮、钾肥的最佳施用量。试验表明:岳优9113作晚稻种植,在施P2O5 72 kg/hm2的基础上,施纯N 195 kg/hm2、K2O 150 kg/hm2最适宜。In order to find out the optimum fertilizer rate of N and K for Yueyou9113, an experiment with different N and K fertilizer rates was conducted to Yueyou9113 in Gengkou Town of Yueyang County in 2001. The results showed that planting Yueyou9113 as late rice, on the basis of applying P205 with 72 kg/hm2, the optimum fertilizer rate of N and k was 195 and 150 kg/hm2, respectively.
