| 摘 要： | 接种试验证实潜根线虫侵染水稻能引起减产，主要是减少有效穗和千粒重；返青期为感病期，这一时期每株稻苗接种300条和470条潜根线虫，分别减产8.8%和13.5%。综合防治措施包括烟 稻轮作、稻草还田、冬翻冬种、利用耐病品种和药剂防治。返青期为防治适期。

| Abstract: | Inoculation tests showed that Hirschmanniella oryzae could cause yield losses of rice, especially reduced the number of panicles and grain weight. The susceptible stage of rice is the reviving stage, inoculations of300 and 470 nematodes per plant caused 8. 8% and 13. 5% yield loss at the stage. Integrated control measures included tobacco rotation with rice, rice straw return to paddy field, winter ploughing and winter planting, use of tolerant rice cultivars. The reviving stage of transplanted rice seedling is the optimum time of chemical control for riceroot nematodes. |
