本研究对塔河林区火烧原木害虫进行了抽样调量,确定云杉小黑大牛(Monochamus sutor L.)是威胁木材的主要害虫,并根据其生物学特性,进行了水存法、涂刷法和熏蒸法等一系列现场治理试验。试验结果表明,采用这些方法保存火烧原木均行之有效。其中,熏蒸法选用磷化铝作熏蒸剂,具有使用方便、安全可靠、渗透力强、杀虫效果显著等特点。 In this study, we sampled and adjusted the burned log pests in Tahe Forest Region to determine that Monochamus sutor L. was the major pest threatening timber. Based on its biological characteristics, Brush and fumigation and a series of on-site management experiments. The test results show that the use of these methods to save fire logs are effective. Among them, the fumigation method uses aluminum phosphide as a fumigant, which has the advantages of convenient use, safety and reliability, strong penetrating power and remarkable insecticidal effect.
