【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。更多还原

【Abstract】 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 11.1,18.8 μmol/(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.更多还原
