| 摘 要： | 研究结果显示,康氏木霉(Trichoderma koningii)以菌丝缠绕、博贴等形式寄生于病例菌的菌丝上,吸取其营养,并产生抑菌物质,致使病茵丝的断裂,原生质凝固,直至死亡.大田小区实验和大面积防治示范部表明,康氏木霉可有效防治棉立枯病(Rhizoclonia solani)等土传病害,降低其发病率和发病程度.

| Abstract: | The acrial hyphac of T. koningii were observed by optical and electronic microscopes, coiling tightly anound the hyphac of R. solani and growing along in straight or wavy lines. The protoplasm of the attached hyphac coagulated, and I'inaly these hyphac fractured and decomposed. The control experiments showed that T.koningii could cffcctivcly control R.solani which was carried by soil, lowing its incidence and severity. |
