摘要
进行人工、割灌机、大型挖掘式平茬机3种方式平茬沙柳Salix psammophila防治柳毒蛾Stilpnotia salisis试验。结果表明:人工平茬和大型挖掘式平茬机平茬沙柳防治柳毒蛾,越冬幼虫平均虫口减退率均为100%,明显高于割灌机平茬;人工平茬劳动强度大,效率低,成本高,平茬质量不高;大型挖掘式平茬机平茬效率高、成本低、平茬质量高,建议大面积平茬沙柳防治柳毒蛾时使用。
Stumping Salix psammophila with manual tools, brush cutter and large stumping machine was conducted to control Stilpnotia salisis. The results showed that the average decrease rates of overwintering larvae population reached 100% in the stumping with both manual tools and large stumping machine, significantly higher than that in the stumping with the brush cutter. Stumping with manual tools was of great labor intensity, low working efficiency, high cost and poor quality. Stumping with large stumping machine was of high working efficiency, low cost and high quality, and was recommended for large area control against S. salisis.
