本文选用几种市场上常见的农用杀菌剂,在春季播种前对唐菖蒲种球和土壤进行消毒处理,以选择防治唐菖蒲球茎病害的有效药剂。试验结果表明,敌克松、多菌灵、甲基托布津三种杀菌剂在适当浓度下对唐菖蒲球茎病害都有一定的防治效果。其中多菌灵300倍液和甲基托布津100倍液浸球防治效果最好,可使球茎发病率降低44.4%和42.9%,而且由于有效地控制了病菌,植株的出苗力、生长势和繁殖能力屯有提高。土施敌克松进行土壤消毒如浓度使用不当,会对种球萌芽、植株生长繁殖产生强烈的抑制作用,防病能力下降。
This article selected several common market fungicide, sowing gladiolus bulbs and soil disinfection before sowing in spring to choose effective prevention and treatment of gladiolus bulbs. The test results showed that the three fungicides such as Nixon, carbendazim and thiophanate-methyl all had certain control effects on gladiolus bulbs under the proper concentration. Carbendazim 300 times and thiophanate-methyl 100 times liquid immersion ball control effect of the best, can reduce the incidence of bulbs 44.4% and 42.9%, and due to the effective control of germs, plant emergence, growth Potential and reproductive capacity increased. Soil Kesi soil disinfection, such as the use of improper concentration, germination will bulbs, plant growth and reproduction have a strong inhibitory effect, anti-disease ability decreased.
