阐述了沿日本海一侧的日本各地发生的较大规模的被称为“第 2 松材线虫病”的栎类树木枯死的灾害症状、原因及其防治。当前研究结果认为,引起栎类树木死亡的直接原因是一种目前尚未正式定名的有害菌,文中被称为“栎树菌”,这种有害菌通过栎长小蠹进行传播的。由于该虫易侵入生长势相对较弱的栎类立木,通常危害木的树龄在 20 年以上,且以 40~50 年居多,通过钻孔注入适量的NCS(威百亩)等药剂后;用胶贴纸带包裹,可起到防治和杀灭栎长小蠹及“栎树菌”的目的。
Describes the symptoms, causes, and preventions of the disaster of the oak trees, known as “the second pine wilt disease”, that have occurred along the Japan Sea side across Japan. The current study concluded that the direct cause of the death of the oak tree is a currently unrecognized harmful bacterium known as “oak” bacteria, which is transmitted by the oyster oyster. As the insects easily invade the relatively weak growth potential of oak wood, usually harmful wood age more than 20 years, and the majority of 40 to 50 years, through the hole into the amount of NCS (Wei Baimu) and other agents; with Adhesive tape wrapped, can play a prevent and kill omega beetles and “oak bacteria” purposes.
