摘　　要：本试验以来源于多粘类芽孢杆菌(Paenibacillus polymyxa)LM-3菌株的极端嗜热多肽APPLM3为主效成分配得5种微生物源生防乳剂,并用它们对水稻苗瘟进行了田间防效试验。试验结果表明,这5种乳剂的防效都优于LM-3拮抗液直接喷雾,其中处理AB_4的防效最佳,达80.73%,其拮抗成分、吐温80、乳化剂OP、溶剂的质量比为50.00:6.50:1.75:41.75。本文报道了常温细菌产生的极端嗜热多肽对稻瘟病菌表现出强的拮抗作用。Extremely Thermophilic Polypeptide APPLM3, originated from Paenibacillus polymyxa LM-3, has been utilized as main effective element to produce five （5） microbial emulsions, which have been applied into field effects tests against Rice Leaf Blast Fungus. The result shows the preventative effects of the five emulsions are better than direct spraying of LM-3 antagonistic fluid. The effects AB4,of the five emulsions is the best, reaching 80.73%. The quantitative ratio of its antagonistic component, Tween（R） 80, emulsification agent OP and solvent agent is 50.00：6.50：1.75：41.75 o The essay reports the strong antagonistic effects of Extremely Thermophilic Polypeptide, produced by normal temperature bacteria, against Rice Blast Fungus.
