　　选用张家口地区生产上常用的燕麦品种坝莜一号为试材，以当地尿素追施量300 kg/hm2为基准（100％全量化肥处理），采用微生物菌肥拌种（菌肥施用量15 kg/hm2）然后减少化肥施用量（即试验设化肥施用量100％、75％、50％和0）的方法，研究了菌肥拌种＋化肥不同追施量处理对燕麦生长和产量的影响。结果表明：播种前用微生物菌肥15 kg/hm2进行拌种，而后配合追施尿素150 kg/hm2（三叶期追施60％、拔节期追施40％）效果最好。该处理能够促进燕麦籽粒灌浆，株高、穗长、穗粒重和千粒重最大，产量最高（5681.25 kg/hm2），较传统的全量化肥处理增产显著（增产率10.18％）。

The local conventional variety Bayou No.1 in Zhangjiakou area was selected as the test material , taking the urea topdressing amount of 300 kg/hm2 as the benchmark, by the methods of reduced the amount of fertilizer ( the amount of chemical fertilizer was 100%, 75%, 50% and 0 of the benchmark ) after seed dressing with microbial bacterial manure , the effects of applied different amount of chemical fertilizer after seed dressing with microbial bacterial manure on the growth and yield of oat were studied.The results showed that the effect of urea topdressing amount of 150 kg/hm2 ( topdressed 60%at trefoil stage, topdressed 40% at jointing stage) after seed dressing with microbial bacterial manure of 15 kg/hm2 before sowing was best, under the treatment the grain filling was accelerated, plant height, ear length, grain weight per ear and 1 000-grain weight of oats were largest, the yield was highest and was significantly higher than that of total amount of chemical fertilizer treatment , the increased rate was 10.18%.
