江西大豆锈病发生及防治的研究

Study on Occurrence and Control of Soybean Rust in Jiangxi

研究结果表明 ,大豆锈病在江西主要分布于浙赣铁路线以南 ,特别是以赣南山区、吉泰盆地发生最为严重 ,以为害 (夏 )秋播大豆为主 ,年发病面积 4万hm2 左右 ;一般年份大豆锈病为害造成的产量损失率达 1 0 %～ 40 % ,与施药保护区相比 ,品种“八月黄”的产量损失率达 1 6 .8% ;推广种植抗病品种是防治大豆锈病最经济有效的方法 ,“玉山青皮豆”、“日向”、“中油 84-87”、“中油R -34”、“九月黄”、“SK1”等品种的表现较好 ,抗性较强 。

The research results show that soybean rust is mainly distributive in south of Zhe-Gan railroad in Jiangxi,especially in Ji-Tai basin and mountain area of southern Jiangxi, and is mainly harmful to summer and autumn sowing soybean,its occurrence area is about 40 000 hm\+2 and rate of yield loss caused by this disease is 10%～40% every year,the yield of soybean “Bayuehuang” is decreased by 16.8% as compared with that of the same variety protected by spraying “Daconil” .Planting disease resistant varieties such as “Yushanqingpidou”,“Rixiang”,“Zhongyou 84-87”,“Zhongyou R-34”,“Jiuyuehuang” and “SK1” is the most effective way to control the disease.\;
