丝虫属

The results showed that the quantities of plant parasitic nematodes of Aphelenchoides and Aphelenchus increased at a speed of geometric order after one growing season,which indicated that the two kinds of nematodes had highly potential risk.

研究结果表明栽培前种球内的优势植物线虫——拟滑刃属和滑刃属线虫数量在百合一个生长周期结束后均以几何级数的速率增长；栽培前检出数量极少的垫刃属线虫，生长周期结束后却大量出现；栽培前少量检出的短体属、矮化属、根结属、丝尾垫刃属和伪垫刃属的线虫，周期结束后，均未再检测到。

Five species belonged to five genera were extracted from soil samples which were Helicotylenchus digonicus, Tylenchorhynchus maximus, Psilenchus hilarulus, Filenchus vulgaris and Aphelenchus avenae. Except A.

结果表明：从洋葱根际土壤样品中共分离鉴定出线虫5个属5个种，包括喜悦平滑垫刃线虫、普通丝尾垫刃线虫、双角螺旋线虫、最大矮化线虫和燕麦真滑刃线虫。

The 111076 nematode individuls were classified into 43 genera and 4 trophic groups. Among them, 32 genera of nematodes belong to beneficial un-plant parasitic (bacterivorous, fungivorous, omnivorous/predatory) nematodes and 11 genera of nematodes belong to baneful phytophagous nematodes which accounted for 1/4 of nematode collectivity, especially the nematodes in the genus of Tylenchus and Filenchus, involved 51 (91%) and 42 (75%) species of flowers, repectively.

经鉴定111076条线虫分属43个属，4个营养类群（食细菌、食真菌、杂食/捕食和植物寄生线虫），其中有益的非植物线虫属32个，有害的植物线虫属11个，占总调查属数量的1/4，相对比例较大，特别是垫刃属和丝尾垫刃属的线虫出现的频率较高，涉及花卉51种和42种，分别占调查花卉总数的91％和75％。

I can not make it blossom and suits me

When temperatures are above approximately 80 °C discolouration of the raceways or rolling elements is a frequent feature.

当温度高于 80 °C 左右时，滚道或滚动元件褪色是很常见的特征。
