| 摘 要： | 为验证油菜测土配方施肥的增产效果,掌握三穗县油菜氮肥、磷肥和钾肥的利用率状况,开展了油菜测土配方施肥试验。结果表明:在测土配方施肥优化栽培管理条件下(N︰P︰K=9︰8︰9),油菜产量最高,为154.53 kg/667m~2,分别比无肥区、无氮区、无磷区和无钾区增产92.63%、41.59%、32.36%和13.83%;氮、磷、钾肥料利用率分别为22.75%、38.64%、27.48%。

| Abstract: | In order to verify the effect of fertilizer application on the yield of rape, the utilization rate of nitrogen fertilizer, phosphate fertilizer and potash fertilizer in Sansui County was found out. The results showed that the test optimization cultivation condition under fertilization (N : P : K=9 : 8 : 9) rapeseed yield was the highest, 2317.95 kg/hm2. The increase was 92.63%, 41.59%, 32.36% and 13.83%respectively, compared to the non-fat, non-nitrogen, non-phosphorous and non-potassium regions. Under the conditions of soil testing, the utilization rate of nitrogen, phosphorus and fertilizer was 22.75%, 38.64% and 27.48%, respectively. |
