摘　　要：通过试验,不同水平的施肥量对参试的6个燕麦品种的鲜草产量有一定的差异,在施肥量为磷酸二铵(含N64%)120kg/hm^2、尿素(含N46%)90kg/hm^2时,青引1号产量为15600.00 kg/hm^2,高于其它参试品种;在施肥量为磷酸二铵(含N64%)150 kg/hm^2、尿素(含N46%)120 kg/hm^2时,白燕7号、青引2号、青引1号产量分别为:13866.65、14000.00、14133.55 kg/hm^2,高于其他参试品种;在施肥量为磷酸二铵(含N64%)180 kg/hm^2、尿素(含N46%)150 kg/hm^2时,加燕2号、白燕7号产量分别为:18000.00、16133.35 kg/hm^2,高于其它参试品种。The effects of different levels of fertilization on fresh grass yield of 6 oat varieties were studied.The results showed that the amount of fertilizers,Ammonium Phosphate（ including N64%） and Urea（ including N46%）,was 120 kg/hm2 and 90 kg/hm2,respectively. The yield of Qingyin No. 1 was 15600.00 kg/hm2,which was higher than those of other tested oat varieties; The amount of fertilizers,Ammonium Phosphate（ including N64%） and Urea（ including N46%）,was 150 kg/hm2 and 120 kg/hm2,respectively. The yields of Baiyan No. 7,Qingyin No. 2 and Qingyin No. 1 were 13866.65 kg/hm2,14000.00 kg/hm2 and 14133.55 kg/hm2,respectively,which were higher than those of other tested varieties; The amount of fertilizers,Ammonium Phosphate（ including N64%） and Urea（ including N46%）,was 180 kg/hm2 and 150 kg/hm2,respectively.The yields of Jiayan 2 and Baiyan 7 were 18000.00 kg/hm2 and 16133.35 kg/hm2,respectively,which were higher than those of other tested varieties.
