摘要
植物真菌病害占植物总病害的70%以上,其寄主广泛、发病形式多样、传播途径多,对作物的产量和品质构成严重威胁,给农业生产带来重大经济损失.生物防治技术因其环境污染小、抗药性风险低、对人畜及天敌安全等优点,成为植物真菌病害绿色防控的关键技术支撑.木霉菌作为一类生物防治菌,具有生长快、抗逆性强、重寄生和分泌抗生物质等特性,尤其在真菌类病害的防治方面得到广泛应用.通过综述具有生防活性的木霉菌的种类、抑菌生防谱以及在植物真菌病害防治中的应用与生防机制,为木霉菌在植物真菌病害领域的进一步研究和应用提供参考.
Plant fungal diseases account for over 70%of all plant diseases,they have the characteristics of wide host range,diverse incidence and multiple transmission routes,causing serious economic losses to the yield and quality of crops.Biological control has the advantages of less environmental pollution,less resistance,and safe to humans,animals and natural enemies.It is an important technical support for green prevention and control of plant fungal diseases.Trichoderma has the characteristics of rapid growth,strong stress resistance,hyperparasitism,and secretion of antibiotic substances.It is a crucial biocontrol fungus for preventing and managing plant diseases,particularly in the case of fungal diseases.In this paper,the species of Trichoderma with biocontrol activity,antifungal biocontrol spectrum,application in control of plant fungal diseases and biocontrol mechanism were reviewed,which provided a reference for the further research and application of Trichoderma in the field of plant fungal diseases.
