摘 要：
为发展绿色农业,探讨了蒸汽熏蒸法在防治甘薯茎线虫病中的作用。研究结果表明,在环境温度为23℃,蒸汽持续熏蒸40min条件下,土表下10cm和20cm深处土层最高温度分别可达60.6℃和37.9℃,相应深度薯块中甘薯茎线虫的死亡率分别为100%、88.1%,土样中甘薯茎线虫的死亡率分别为59.6%、60.0%;在环境温度为7℃时,利用蒸汽熏蒸不能有效地控制甘薯茎线虫。在大田或温室大棚中环境温度达到23℃以上时,可使用蒸汽熏蒸法防治甘薯茎线虫及其他病虫害。

摘 要：
Application of steam fumigation for the management of Ditylenchus destructor was investigated in this paper.The results showed when the ambient temperature was 23 ℃ and the duration of steam fumigation was 40 min,the maximum soil temperatures in 10 cm and 20 cm depth reached 60.6 ℃ and 37.9 ℃,respectively.Mortalities of D.destructor in the sweet-potato tubers buried in corresponding depth were 100% and 88.1%,respectively.The mortalities of D.destructor in the soil sample from corresponding depth were 59.6% and 60.0%,respectively.The steam fumigation was useless for the management of D.destructor while the ambient temperature was 7 ℃.The steam fumigation can be used for green management of D.destructor when the ambient temperature reaches 23 ℃.
