放线菌对植物病害的防治作用及应用

摘要

Actinomycetes are one of the most important bio - control micro - organisms which produce antibiotics and enzymes and are advantageous in the bio - control of plant diseases. This study addresses the bio - control of actinomycetes against plant diseases in terms of actinomycetes＇ action on phytopathogen and on the plants＇ disease resistance under the soil environ- ment. The paper also gives a brief introduction to the applications of actinomycetes in the bio - control of plant diseases, research hotspot and development trend.%放线菌是产生抗生素和酶的重要微生物资源之一，在防治植物病害中有很多优势．主要从放线菌与植物病原菌的作用和土壤环境中的放线菌对植物的抗病作用两方面，介绍了放线菌对植物病害的防治作用；简述目前放线菌在植病生防中的应用状况；以及研究热点和发展趋势．
