白蚁对林木的危害,随着林业生产的不断发展而被引起重视。经初步观察:林木上的白蚁有6—7种,其中以黑翅土白蚁危害较严重,分布较广,在镇江、南京、苏州等地均有发现。受害树种有杉木、刺槐、枫杨、栎树、松树、毛竹、茶叶、桑树等,以杉木受害较普遍。在我场杉木被害株率达87%。黑翅土白蚁蛀食杉木树皮,咬破形成层,产生流脂现象;在地下啃食树根,使杉木生长受到影响,危害严重者枯死。对毛竹啃食地下鞭和嫩芽,蛀食竹笋,影响竹林生长发育。对茶叶、桑树蛀食地下根部,影响生长和产叶量。我们遵照毛主席“实践、认识、再实践、再认识”的教导,近二年来对黑翅土白蚁进行了观察研究,解剖和分析了大量的蚁巢,初步了解它的生活习性,掌握了防治方法。现将结果整理如下,错误之处,请指正。 Termite damage to the forest, with the continuous development of forestry production has been paid attention. After preliminary observation, there are 6-7 species of termites in forest trees, of which Termites are more serious and widely distributed in Zhenjiang, Nanjing and Suzhou. Diseased trees are fir, black locust, maple, oak, pine, bamboo, tea, mulberry and so on, the damage is more common in Chinese fir. In our field Cunningham strain 87%. Black-winged termites eaten pine bark, biting the formation layer, resulting in the phenomenon of flow fat; grazing in the ground under the roots, so that the growth of Chinese fir, harms dead serious. Bamboo grazed underground whip and shoots, eating bamboo shoots, affecting bamboo growth and development. Tea, mulberry roots eating underground, affecting growth and leaf yield. In accordance with Chairman Mao’s teachings of “practice, understanding, practice and re-understanding”, we observed and studied the black-winged termites in the past two years. We dissected and analyzed a large number of ant nests to understand their living habits and master the prevention and treatment method. The results are now organized as follows, the wrong place, please correct me.
