| 摘 要： | 对我国北部及中东部9省(直辖市)的57市(县)采集玉米根际土壤样品,从92份土样中共分离到17属植物寄生线虫,即垫刃属(Tylenchus)、丝尾垫刃属(Filenchus)、杆垫刃属(Rhabdotylenchus)、平滑垫刃属(Psilenchus)、叉针属(Boleodorus)、巴兹尔属(Basiria)、矮化属(Tylenchorhynchus)、短体属(Pratylenchus)、小环属(Criconemella)、茎属(Ditylenchus)、纽带属(Hoplolaimus)、盾属(Scutellonema)、盘旋属(Rotylenchus)、螺旋属(Helicotylenchus)、拟盘旋属(Pararotylenchus)、真滑刃属(Aphelenchus)、滑刃属(Aphelenchoides)。其中,矮化属线虫分布较广,占样本总数的58.70%;螺旋属线虫的相对丰度最大,占线虫总数的47.53%,这两属线虫为玉米根际土壤中的优势属。对不同地区线虫种群进行分析得出,螺旋属线虫为山东、安徽、江苏及河南省的优势属,矮化属线虫为黑龙江、吉林、辽宁、北京和河北省(市)的优势属,垫刃属线虫是吉林省的优势属,短体属线虫为辽宁和河南两省的优势属。

| Abstract: | pecies survey of parasitic nematode in rhizospheric soil of corn was carried out in 9 provinces of 57 counties in Northern and Mid-eastern, 92 soil samples of rhizospheric soil of corn were collected and investigate, The investigation revealed that the nematodes belong to 17 generas, namely Tylenchus, Filenchus, Rhabdotylenchus, Psilenchus, Boleodorus, Basiria, Tylenchorhynchus, Pratylenchus, Criconemella, Ditylenchus, Hoplolaimus, Scutellonema, Rotylenchus, Helicotylenchus, Pararotylenchus, Aphelenchus and Aphelenchoides. Tylenchorhynchus spread widely in many regions, in the number of soil samples was 58.70%, Helicotylenchus had the largest relative abundance, in the population number was 47.53%, the two generas were dominant generas in the rhizospheric soil of corn. Helicotylenchus was the dominant genera in Shandong province, Anhui province, Jiangsu province and Henan province, Tylenchorhynchus was the dominant genera in Heilongjiang province, Jilin province, Liaoning province, Beijing and Hebei province, Tylenchus was the dominant genera in Jilin province, Pratylenchus was the dominant genera in Liaoning and Henan province. |
