| 摘 要： | 为控制日益严重的两系杂交稻稻曲病的危害，分别对不同杂交组合按新分级标准系统调查田间病情，并进行多种田间小区药剂试验和综防示范，探讨两系杂交稻稻曲病的发生规律及防治措施，结果表明，两系杂交稻稻曲病的发生与组合的抗性密切相关，稻曲病的田间发生用逻辑斯蒂曲线模型拟合，防治稻曲病的药剂以瘟曲克星的防效最好，防治适期足水稻孕穗未期至破口期。对感病绘经剂防治药两次比施药一次效果好；以推广抗病 基础的综合防治措施切实行可行，防治效果显著。 |

| Abstract: | The results obtained from experiments show that occurrence of false smut of two line system hybrid rice (except resistant crosses) in the fields can be simulated with logistic equation and are closely related with resistance of crosses. Optimum control period of false smut is from the end of boot stage to the rupturing stage of rice. Twice spraying are suitable for susceptibility or more susceptibility crosses. Besides the suiting drugs for rice false smut are selected: Wenqukexing ,Sanzuotong, Laoantong,etc. Wenqukexing is the best drug among them. |
| Keywords: | two line system hybrid rice false smut occurrence logistic equation control |
