摘要
连续3年对唐菖蒲褐腐病进行了系统观测、调查与试验。结果表明,土温20℃时始病,5月下旬至6月下旬(22～24℃)遇高湿阴冷天气形成发病高峰,8月土温高达30℃以上,病害停止发展,10月以后以菌核在土壤中或以菌丝体在病球茎上越冬,成为翌年初侵染源。提出了选留种苗、处理种苗、实行轮作、加强栽培管理、药剂防治的综合防治措施。
Gladiolus gradarensis has been experimented for three years to observe the brown rotten disease. Results shows that the disease appears when soil temperature reaches 20 degrees of Celsius, with peak disease incidence at humid temperature of 22 to 24 degrees （Usu. from late May to late June）. When soil temperature is above 30 degrees （at usual days after August）, this disease disappears. After October bacteria still exist in the soil or gladiolus corm through deep winter till their succession in the following year. the paper has also proposed several preventing measures such as carefully selecting seeds, processing infant plant and rotating crops.
