摘要： 为明确微生物菌肥拌种及减少一定量的化肥用量对燕麦生长和产量的影响，给微生物菌肥在燕麦上的推广应用提供依据，研究了微生物菌肥配合不同用量的化肥对燕麦出苗、各生育期株高、干物质含量和产量的影响。结果表明，各处理间燕麦产量差异显著(F=601.346，P=0.00<0.05)，处理C（菌肥+ 75%化肥）下产量最高为达4189.5 kg/hm2；处理A（全化肥）和B（菌肥+50%化肥）次之，产量分别为3546 kg/hm2和3468 kg/hm2；处理D（对照）产量最低，为3064.5 kg/hm2。因此，使用微生物菌肥对燕麦拌种，可以减少一定量的化肥用量，减轻土壤板结程度，提高燕麦产量。

Abstract: Oat emergence, plant height, dry matter content each growth period and yield under different treatment, using microbial fertilizer seed dressing and reducing the amount of chemical fertilizer, were studied to provide the basis for the promotion and application on oats. Yield under different treatment were significantly different, with the highest yield 4189.5 kg/hm2 under treatment C (microbial fertilizer seed dressing and 75% chemical fertilizer). Yield of treatment A (100% chemical fertilizer) and B (microbial fertilizer seed dressing and 50% chemical fertilizer) were in the middle which were 3546 kg/hm2 and 3468 kg/hm2. The lowest yield was 3064.5 kg/hm2 under the treatment D (CK). Therefore, using microbial fertilizer on oat seed dressing not only can improve oat yield, but also can reduce the amount of chemical fertilizer and alleviate the degree of soil compaction.
