中文摘要: 【目的】 为摸清堤坝土埝中氯化钠对黑翅土白蚁Odontotermes formosanus Shiraki 生存的影响,合理确定防治黑翅土白蚁危害堤坝的氯化钠含量值,确保堤坝工程安全运行。【方法】 选取有黑翅土白蚁生存和无黑翅土白蚁生存两类堤坝的土埝,进行土埝中氯化钠含量的测试。【结果】 有黑翅土白蚁生存的堤坝土埝氯化钠含量在0.02%以下,无黑翅土白蚁生存的堤坝土埝氯化钠含量在0.19%以上。【结论】 研究成果对黑翅土白蚁危害堤坝的防治具有很好的实用价值。
英文摘要: [Objectives] To determine the influence of sodium chloride in dam soil on the survival of Shiraki, and to determine the sodium chloride content required to protect dams from O. formosanus and therebyensure their safe operation. [Methods] We selected two types of dam soil with and without O. formosanus toconduct tests ofsodium chloride content. [Results] O. formosanus was found in soil with < 0.02% sodium chloride content, but not in soil with a sodium chloride content was > 0.19%. [Conclusion] The results have practical implications for preventing O. formosanus damage to dams.
