| 中文摘要: |
| 于2009-2011年对河北省10个地区55个县的小麦孢囊线虫发生情况进行系统调查，共采集土样719份。调查结果表明：孢囊总检出率为52.7%，其中冬麦区孢囊的检出率为61.2%，春麦区孢囊检出率为0。石家庄地区孢囊检出率最高，达90%，各地区孢囊检出率大小顺序依次为：石家庄、邢台、保定、邯郸、廊坊、衡水、唐山、沧州、张家口、承德。其中唐山滦南县与任丘市孢囊线虫发生最为严重，分别有11.8%和7.7%地块每100 mL土中的孢囊数量在40个以上。沙壤土中孢囊线虫的检出率最高，达63.0%，壤土与黏土中小麦孢囊线虫的检出率分别为60%和50%，在沙土地块未发现小麦孢囊线虫。依据孢囊线虫的形态特征，河北危害小麦的孢囊线虫种类应为禾谷孢囊线虫(Heterodera avenae)。 |

| A systematic survey on the occurrence of cyst nematodes of wheat in 55 counties of Hebei was carried out during 2009-2011. A total of 719 soil samples were collected. The results showed that the total incidence of cyst nematodes of wheat in Hebei was 52.7%, whereas the incidence of cyst nematodes in winter wheat and spring wheat were 61.2% and 0%, respectively. The incidence of cyst in Shijiazhuang Region is 90% and is the highest among all the regions investigated in Hebei. Ranking of cyst incidence from high to low was Shijiazhuang, Xingtai, Baoding, Handan, Langfang, Hengshui, Tangshan, Cangzhou, Zhangjiakou, Chengde. A higher densities of cysts occurred in Luannan county of Tangshan and in Renqiu city, with the densities of more than 40 cysts /100 mL soil in 11.8% and 7.7% fields, respectively. The incidence of cysts in sandy loam soil was 63.0%, while those were 60%, 50% and 0% in loam soil, clay soil and sandy soil, respectively. All the cyst nematodes of wheat in Hebei were identified as Heterodera avenae based on the morphological characteristics. |
