摘要
对小麦茎基褐腐病在江苏省 4 8个县 (市 )的发生情况进行了调查研究 ,结果显示 :沿江、沿海及苏南丘陵地区 (镇江 )病害一般发生较重 ,病株率 4 8%～ 90 % ;里下河和沿洪泽湖地区病害发生多属轻到中等 ,病株率 1 0 %～ 39% ;苏北的徐州、连云港、宿迁等地病害发生很轻微 ,病株率在 1 %以下 .调查发现 :小麦茎基褐腐病发病程度与小麦纹枯病发病程度呈负相关 .产量损失测定表明 :小麦茎基褐腐病对不同小麦品种影响不一 ,扬麦 1 5 8产量损失率较高 ,达 8.5 % ,豫麦 1 8产量损失率最低 ,仅 0 .1 9% .
The epidemic levels of the disease caused by wheat brown foot rot in 48 counties of Jiangsu Province were investigated. The disease in the regions along the Yangtse River, the east coast and the Zhenning hills was serious with disease incidences from 48% to 90%. The disease in the regions along the Lixiahe and around the Hungze Lake was moderate with disease incidences 10% to 39%. But in the regions such as Xuzhou, Lianyungang and Suqian cities, the disease was minor with disease incidences less than 1%. Negative correlation between the occurrence of wheat brown foot rot and that of wheat sharp eyespot was observed in this study. The tested result of yield loss showed that effect of the disease on wheat yield losses varied with wheat varieties. Yangmai 158 had a higher loss rate (8.5%), whereas the loss rate of Yumai 18 was much lower (0.19%).
