姜瘟病又称腐烂病或青枯病,在浙江、广东、湖北、四川、山东等地均有发生。莱州市地处胶东半岛,大姜种植历史悠久,种植面积已达2000hm~2。由于病菌的历年积累,近年来姜瘟病普遍发生,轻者减产10%～20%,重者减产50%以上,严重的甚至造成绝产,产量和效益受到很大影响,严重制约了种植规模的扩大。对此,莱州市植保站和中国农业科学院、南京农业大学等有关专家组成专门技术小组,对姜瘟病防治技术进行联合攻关研究,探索出一整套姜瘟病综合防治技术,取得了很好的防治效果。
Also known as the rot of ginger blast or bacterial wilt, in Zhejiang, Guangdong, Hubei, Sichuan, Shandong and other places have occurred. Laizhou City is located in Jiaodong Peninsula, ginger has a long history of planting, planting area has reached 2000hm ~ 2. As the accumulation of bacteria over the years, in recent years, the prevalence of ginger blast, the light reduction of 10% to 20%, the heavy reduction of more than 50%, causing serious or even absolute loss, yield and benefits have been greatly affected, seriously restricting the scale of planting expand. In this regard, Laizhou Plant Protection Station and the Chinese Academy of Agricultural Sciences, Nanjing Agricultural University and other experts composed of specialized technical groups on the prevention and control of blast disease joint research, to explore a set of comprehensive prevention and control of blast disease, and achieved good control effect .
