查询词典 jack pine

Contrast tests in three places during 1997 and 1998 showed that the trapping capability of 450Wlight was obviously stronger than that of 20W light.The fluctuation of trapped japanese pine sawyer,Monochamus alternatus was consistent with that of natural emergence.The pine wilt nematodeBursaphelenchus xylophilus can be extracted from trapped male and female adult bodies of JPS.

三地两年的对比试验结果表明，450W高压汞灯诱杀松墨天牛Monochamus alternatus Hope效果明显优于20W黑光灯，灯光引诱结果与松墨天牛自然羽出情况基本一致，灯光诱集的松墨天牛雌雄成虫体上均可分离到松材线虫Bursaphelenchus xylophilusNickle。

Some strains of the nematode-bearing bacteria were bioassayed for their parasitism. All these bacteria can totally not grow or grows badly on the media incorporating the extracts of pine trees, indicating some substances existing in the trees will harmful to the bacterial strains, which is further convinced by preliminary inoculation showing that single bacterial species will not infect Pinus thugbergii. Hence, the growth and reproduction of the nematode-carrying bacteria, which could produce toxic substances causing the death of the tree cells, is closely related to the nematodes, when they first enter to the trees. In the same time, the activity of bacteria improved the circumstances for which nematodes are living, which in turn will beneficial to the growth of nematodes. Thus, there is a complicated interaction among nematodes, bacteria, and pine trees.

对松材线虫携带的细菌的部分菌株进行了寄生性测定，表明这些细菌在添加松树提取液的细菌培养基中不能生长或基本不能生长，这说明松树体内可能存在某些不利于细菌生长的物质，同时初步的接种试验证实，单独的细菌接种不能感染健康的黑松，因此，线虫携带的致病细菌在最初进入树体时，其生长和繁殖与线虫密切相关，结合细菌产生的毒性物质可造成黑松细胞死亡的情况，说明细菌的生长与线虫有关，同时，细菌的活动改变了线虫在松树内的生长环境，使环境变得有利于线虫的生活，因此，线虫、细菌和松树三者存在着复杂的生物关系。

In the fire performance study, the charring rate of side and bottom were ranged from 0.587 to 0.750 mm/min and 0.709 to 0.897 mm/min for China fir glulam, 0.643 to 0.770 mm/min and 0.644 to 0.911 mm/min for Japanese cedar glulam, 0.608 to 0.757 mm/min and 0.614 to 0.817 mm/min for Taiwania glualm, 0.588 to 0.627 mm/min and 0.632 to 0.694 mm/min for Douglas-fir glulam, and 0.530 to 0.568 mm/min and 0.566 to 0.583 mm/min for Southern pine glualm, respectively. The results indicated that the charring rate in all glulam showed a decreasing order in Taiwania＞Japanese cedar ＞China fir ＞Douglas-fir＞Southern pine glulam.
