摘　　要：为探究微生物菌肥对禾本科牧草种子发芽效果的影响,设置不同的菌肥浓度,对3种不同的禾本科牧草种子进行发芽试验,并观察其对牧草种子萌发的影响。结果表明:除青海草地早熟禾外,微生物菌肥对于其他两种禾本科牧草种子发芽率、发芽势和发芽指数均存在一定程度的抑制作用;对于青海草地早熟禾而言,除部分菌肥浓度较高的试验组发芽势表现出抑制作用外,其他试验组的发芽势均表现出促进作用,对其发芽率和发芽指数而言,则整体表现出促进作用。微生物菌肥抑制垂穗披碱草和青海中华羊茅种子萌发,而对于青海草地早熟禾牧草种子萌发则表现出促进效果。In order to explore the effect of microbial fertilizer on the germination of gramineous forage seeds,different concentrations of microbial fertilizer were set up to carry out germination experiments on three different gramineous forage seeds,and their effects on the germination of forage seeds were observed.The results showed that the microbial fertilizer had a certain degree of inhibitory effect on the germination rate,germination potential and germination index of the other two gramineous forage seeds except Poa pratensis cv.Qinghai.For Poa pratensis cv.Qinghai,except for the high concentration of some bacterial fertilizer,the germination potential of the other experimental groups showed a promoting effect,and the germination rate and germination index showed a promoting effect as a whole.Microbial fertilizer inhibited the seed germination of Elymus nutans and Festuca sinensis cv.Qinghai,but promoted the seed germination of Poa pratensis cv.Qinghai.
