| 摘 要： | 针对白背飞虱和稻纵卷叶螟田间发生和防治的实际情况,通过试验建立"两迁"害虫同时危害时的回归方程,依据当地农业生产现状,计算得出实际经济允许损失N=16.16。由满足0.013X1+0.287X2-0.539=16.16,测得"两迁"害虫同时危害的一组动态的复合防治指标。

| Abstract: | Based on the actual situation of field occurrence and control of Sogatella furcifera and Cnaphalocrocis medinalis Güenée,the test established the regression equation when the two pests harmed at the same time.Based on the local agricultural production level,the economical loss(N) was 16.16.Based on 0.013X1+0.287X2-0.539=16.16,one set of developmental complex damage with Sogatella furcifera and Cnaphalocrocis medinalis Güenée could be calculated. |
