摘　　要：为研究多黏类芽孢杆菌菌剂对玉米产量和病害的影响,采用随机区组试验方法,进行多黏类芽孢杆菌菌剂对玉米影响的田间试验。结果表明,15、30 kg/hm^(2)多黏类芽孢杆菌菌剂与化肥共同施用比单独施用化肥的出苗率高4.1%、5.3%,玉米幼苗叶绿素含量分别高7.90、14.48 mg/g,过氧化氢酶活性分别高11.1、18.8μmol/(g·min),过氧化物酶活性分别高7.47、15.73 U/(g·min),对玉米根腐病防效分别为74.27%、80.50%,对玉米的增产率分别为9.68%、17.68%。因此,多黏类芽孢杆菌菌剂可和化学肥料在玉米种植时一起作为基肥使用,可以减轻根腐病的发生,提高玉米产量,能够起到很好的减肥减药作用。In order to study the effect of Paenibacillus polymyxa inoculum on corn yield and disease,a randomized block test method was used to conduct a field experiment of the effect of Paenibacillus polymyxa inoculum on corn.The results showed that 15,30 kg/hm^(2) of Paenibacillus polymyxa inoculum and chemical fertilizers had a 4.1%and 5.3%higher emergence rate than chemical fertilizer alone,and the chlorophyll content of maize seedlings was higher by 7.9 and 14.48 mg/g,respectively.Catalase activity was 11.1,18.8μmol/(g·min)higher,and peroxidase was 7.47,15.73 U/(g·min)higher,respectively.The control effects on corn root rot were respectively 74.27%,80.50%,the increase rate of corn yield was 9.68%,17.68%.Therefore,Paenibacillus polymyxa could be used as a base fertilizer together with chemical fertilizers when planting corn,which could reduce the occurrence of root rot,increase corn yield,and had a good weight loss and drug reduction effect.
