剑河县位于贵州省东南部,海拔最低348米,最高1626米,稻田大多为海拔400～1000米的塝坡、山弯地区和沟冲中,有利于稻杆蝇Chlorops oryzae Matsumura的发生和为害。研究其预测及防治,对改变山区水稻低产有着重要意义。此项工作是1979年春开始的,现将近5年来的调查和观察校正结果,报道于后。 Jianhe County is located in the southeastern part of Guizhou Province, with the lowest altitude 348 meters and the highest 1626 meters. Most of the paddy fields are slopes, mountain bend areas and ditch Chongzhong of 400-1000 meters above sea level, which are conducive to the occurrence and damage of Chlorops oryzae Matsumura . Studying its prediction and prevention and control is of great significance for changing the low yield of rice in mountainous areas. This work started in the spring of 1979, and the results of the survey and observation of nearly five years now are reported later.
