| 中文摘要: |
| 为了明确小麦孢囊线虫病的扩散传播途径，调查病区农用机械、麦田翻耕后田间及其周边流水中小麦孢囊线虫的孢囊数量。结果表明，收割机、旋耕机和播种机上土样的孢囊检出率分别为27.1%、51.6%和44.0%，麦稻轮作的病田中，浪渣的孢囊检出率为58.3%，翻耕后麦田积水、沟渠和小河流中的孢囊检出率分别为33.3%、22.7%和7.7%。说明农业机械的跨区作业和水流是小麦孢囊线虫病传播、扩散的重要途径。 |
| 英文摘要: |
| This study aimed to investigate the diffusion ways of the cereal cyst nematode (CCN). The cyst numbers of CCN in the soil sticked to agricultural machinery in wheat fields and in the water around were investigated in the CCN epidemic areas. The detection rates of cysts in the soil collected from harvester, rotary tiller and seeder were 27.1%, 51.6% and 44.0%, respectively. In wheat rice rotation fields, the detection ratio of cysts was 58.3% in the floating leftovers. In ploughed wheat fields, the detection rates of cysts in the field accumulated water, in the water from ditches and in the running water were 33.3%, 22.7% and 7.7%, respectively. The results indicated that the agricultural machinery operation across different areas and running water might be one of the main ways of CNN diffusion. |
