摘要

The grape cultivation area in Luolongzhuang of Wenlan,Yingfang,Liucun and Shiqicun of Caoba in Mengzi City,Yunnan Province were surveyed from October 2014 to February 2015. Using five-point sampling method,approximately 2 kg of rhizosphere soil were collected from plants with weak growth and brown and wilting root,and 28 soil samples in total were collected. Through morphological identification,the species of parasitic nematodes in rhizosphere soil of grapes were preliminarily identified. There were three genera and four species of parasitic nematodes in grape,including A. avenae( Aphelenchus avenae Bastian,1865),R. reniformis( Rotylenchulus reniformis Linford et Oliverira,1940),H. dihytera [Helicotylenchus dihytera Sher Cobb,1893,1961] and H. pseudorobustus [Helicotylenchus pseudorobustus Golden( Steiner,1914),1956].
