摘要
2012年5—10月在田间自然感病条件下对开远、临沧、保山、德宏4个地区41个国家甘蔗体系新品种(系)主要病虫害发生情况进行调查,明确了新品种(系)中开远综合试验站的云蔗05-49、云瑞06-189、云蔗05-51、桂糖30号、云蔗99-91受甘蔗螟虫危害重;云蔗03-103受黑穗病、花叶病危害重,云蔗99-91、桂糖02-467受花叶病危害重。德宏和临沧综合试验站的福农38号、福农1110、粤甘24号、云蔗99-91、桂糖31号、云蔗99-596、云蔗03-258、桂糖02-901、云瑞06-189受梢腐病危害重,福农40号、柳城03-1137、粤甘26号、粤甘35号、粤甘39号受锈病危害重,福农0335、桂糖31号、桂糖32号受褐条病危害重。4个地区甘蔗黄斑病和黄叶病危害重的品种较少。并根据以上结果提出了病虫害防治和品种布局建议。
The occurrence and distribution of the diseases and insect pests in the field were investigated from 41 sugarcane varieties/lines of national sugarcane system in Kaiyuan, Lincang, Baoshan and Dehong areas from May to October of 2012. The results showed that the varieties of Yunzhe 05-49, Yunrui 06-189, Yunzhe 05-51, Guitang 30 and Yunzhe 99-91 were seriously injured by sugarcane borer, Yunzhe 03-103 was seriously harmed by sugarcane smut and mosaic disease; Yunzhe 99-91 and Guitang 02-467 were badly infected by sugarcane mosaic disease, in Kaiyuan comprehensive experimental station area. Nine varieties of Funong No. 38, Funong 1110, Yuegan No. 24, Yunzhe 99-91, Guitang 31, Yunzhe 99-596, Yunzhe 03-258, GuiTang 02-901 and Yunrui 06-189 were seriously harmed by sugarcane top rot disease; 5 varieties of Funong No. 40, Liucheng 03- 1137, Yuegan No. 26, No. 35 and No. 39 were seriously harmed by sugarcane rust; Funong 0335, Guitang 31 and Guitang 32 were badly harmed by sugarcane brown streak disease, in Dehong and Lincang comprehensive experimental station area. Fewer varieties were seriously harmed by Yellow leaf disease and yellow macular disease in the total experimental areas. The pest control and rational distribution of sugarcane varieties were proposed according to the above results.
