摘　　要：2010年通过不同施肥量对燕麦丰产性进行试验研究发现,在中等以上肥力的地块中,燕麦的整个生长期施用N150P300或N150P150的产量最高。处理N150P300的燕麦平均株高为68.43 cm,穗长16.06 cm,千粒质量22.3 g,株有效穗数为2.88穗,小区平均产量居第1位,为7.72 kg;处理N150P150的株高为67.67 cm,穗长16.57 cm,千粒质量22.2 g,株有效穗数3.25穗,小区平均产量居第2位,为7.27 kg,且其他性状表现良好。The results of experiment on effects of fertilization rate to oat fertility in year of 2010 showed that,in fields of above medium fertility,when N150P300 or N150P150 was applied during the whole growing stage,high yield had got.In N150P300 treatment,oat had mean plant height of 68.43 cm,ear length 16.06 cm,thousand-seed weight 22.3 g,available 2.88 ears per plant,and the first plot mean yield was 7.72 kg;While in N150P150 treatment,the plant height was 67.67 cm,ear lenght 16.57 cm,thousand seed weight 22.2 g,available 3.25 ears per plant,and the second plot mean yield 7.27 kg;And the other traits all had good performance.
