摘　　要：通过平板对峙培养法从玉米秸秆还田土中筛选得到对小麦全蚀病、小麦根腐病、小麦纹枯病都有防效的拮抗细菌19株,抑菌率在41.57%～93.36%之间,结合其对玉米秸秆性降解性能,发现菌株F1514即对小麦根病具有较强的拮抗作用,又对玉米秸秆具有一定的分解能力和适应性。菌株F1514对小麦全蚀病菌、小麦根腐病菌和小麦纹枯病菌的抑菌率分别为92.92%、90.81%、63.26%;在测定时间内其对粗纤维降解率的为10.92%。经初步鉴定,该菌株为芽孢杆菌属（Bacillus.sp）。19 bacteria strains, isolated from maize straw retention field, had inhibition effect to the three pathogenic fungi of wheat root diseases, and then were tested by the trial of degradation and adaptation activity of maize straw. Only a strain （F151g） had high inhibition efficacy and adaptation to maize straw. The inhibition effects of F1514 to the three pathogenic fungi of Gaeumannomyces graminis （Sacc.） Arxer Oliver, Bipolaris sorokiniana （Sacc.） SHoem., Rhizoctonia cereali Vander Hoeven are 92.92%, 90.81%. 63.26%, respectively. It＇ s identified as Bacillus. Sp.
