【摘要】 于2002~2003年间,发现福建农林大学南平校区柳杉绿化林带有严重病害发生,经过病原鉴定为柳杉赤枯病(Cercosporasecoiae)。同时,从柳杉病区林木根系及根际土壤分离到大量双宫螺旋线虫(HelicotylenchusDihystera)、马丁矮化线虫(Tylenchorhynchusmartini)、肾形肾脏线虫(Rotylenchulusreniformis)、微小针线虫(Paratylenchusminuts)、垫刃线虫(Tylenchusplatycephalus)及一定量的盘旋线虫(Rotylenchuscaudnphasmidius)、美洲剑线虫(Xiphinemaamericanum)、长针线虫未定种(Longidorussp.)、尾滑刃线虫(Aphelenchoidescomposticola)、环线虫未定种(Macroposthoniasp.)、昏暗毛刺线虫(Trichdorusobscurus)、燕麦真滑线虫(Aphelenchusavenae)。根据相关性分析和有关报道,认为柳杉根际线虫某些类群的群体数量与柳杉赤枯病的发生有明显的相关性。更多还原

【Abstract】 From 2002 to 2003 , in Nanping district of Fujian University of Agriculture and Forestry ,the serious disease of Pestalotiopsis apiculatus developed in the virescence zone of Cryptomeria fortunei. Many pests were collected and isolated from Cryptomeria fortunei’s roots and rhizosphere soil in the area . The main species were Helicotylenchus dihystera , Rotylenchulus reniformis ,Tylenchorhynchus martini ,Paratylenchus minuts , Tylenchus platycephalus .The others were Rotylenchus caudnphasmidius ,Xiphinema americanum ,Longidorus sp.Aphelenchoides composticola , Macroposthonia sp. , Trichdorus obscurus , Aphelenchus avenae . According to relativity analysis and related reports , there is the distinct relativity between the nematode population of some species and the development of Pestalotiopsis apiculatus .更多还原
