摘要
试验表明 :块状混交模式是控制杨扇舟蛾的最佳混交模式 ;在块状混交模式下 ,杨×槐、杨×桐两种混交类型为最佳混交类型 ;在块状混交模式的 3种混交比例中 ,杨×槐。
The experiment showed that the forest mixed by groups was the optimum mingled mode against Clostera anachoreta.In that mode,the mixed poplar and sophora forest and mixed poplar and paulownia forest were 2 optimum mingled types.The difference of control function against Clostera anachoreta among the 3 mixed ratios of the 2 types of mixed forests in the mentioned mode was not significant.
