试验证明,人工给棉花接种串珠镰刀菌,可对棉花枯萎病产生交互保护作用;采用五氯硝基苯拌种诱发自然串珠镰刀菌,同样可达到上述目的;在进行交互保护作用的同时,棉花不会因该菌的作用,而出现大量死苗和影响寄主生长发育的现象。另外还观察到,串珠镰刀菌和棉花枯萎菌之间具有互为抑制作用,抑制力强弱,取决于二者先后间隔接种时间的早晚;除两种菌等量分开接种,在培养皿中心产生拮抗带外,二者等量和倍量混合接种,均长出单一的串珠镰刀菌。
The experiment proves that artificial inoculation of Fusarium moniliforme with cotton can produce reciprocal protection to Fusarium oxysporum f. Sp., While Fusarium moniliforme was induced by the treatment with pentachloronitrobenzene, the same purpose can be achieved. At the same time, cotton Not because of the role of the bacteria, and a large number of dead seedlings and affect the host growth and development of the phenomenon. In addition, it was also observed that Fusarium moniliforme and cotton Fusarium wilt each other inhibit each other, the strength of the inhibition, depending on the interval between the two inoculation time sooner or later; in addition to two kinds of bacteria were separately vaccinated in the center of the dish Antagonistic band, both the same amount and times the amount of mixed inoculated, grow a single Fusarium.
