摘要:
为了检测不同处理方式对荧光假单胞菌(Pseudomonas fluorescens)R15在辣椒根部定殖数量和防治辣椒疫病效果的影响,利用重复伤根法、重复伤根接种法、重复浇灌尿素溶液法、重复灌菌液接种法处理接种R15的辣椒苗,测定各个处理组在第一次接种后5~60 d的定殖数量,以及在接种10、25、40、55 d对辣椒疫病的防治效果。结果表明,重复伤根处理对R15菌株的定殖量增加有限;重复伤根接种能使内生细菌的定殖量明显增加,但是多次伤根对植物体造成伤害,植株防治辣椒疫病的能力下降;重复浇灌尿素溶液使内生细菌的定殖量缓慢下降,但是防效提高不显著;重复灌菌液接种能使内生细菌R15在辣椒体内的定殖数量大于105.61CFU/g,防治效果维持在80%~100%之间。因此,生防菌R15的使用方法是在第一次接种后,每隔15~20 d在辣椒根部进行菌液灌根,可以高效防治辣椒疫病。
