大豆胞囊线虫病是中国大豆生产上的最重要的病害之一。本研究通过测定2006~2008年辽宁省26个地区大豆田中的大豆胞囊线虫胞囊密度,明确大豆胞囊线虫在辽宁省的发生和分布情况。在所调查的26个市(县、区)中,88%的大豆产区含有大豆胞囊线虫,平均每百克风干土中超过10个胞囊的地块占73%。其中康平县西关乡的大豆胞囊线虫胞囊密度最高,达到54.33,而开原市、东港市和桓仁满族自治县的大豆胞囊线虫胞囊密度为0,大多数地区的大豆胞囊线虫胞囊密度介于20~55之间。
Soybean cyst nematode disease is one of the most important diseases in China’s soybean production. In this study, we determined the density of soybean cyst nematode in 26 soybean fields in Liaoning Province from 2006 to 2008, and determined the occurrence and distribution of soybean cyst nematode in Liaoning Province. Of the 26 cities (counties, districts) surveyed, 88% of the soybeans in the soybeans contained Soybean cyst nematodes, with an average of 73% of the plots containing more than 10 cysts per 100 grams of dried earth. Among them, the cyst density of Soybean cyst nematode in Xiguan, Kangping County was the highest, reaching 54.33, while the cyst density of Soybean cyst nematode in Kaiyuan, Donggang and Huanren Manchu Autonomous County was 0, and most of the Soybean cyst nematode cysts Density between 20 ~ 55.
