摘要: 摘要: 通过对根结线虫不同病害程度的设施蔬菜根围土壤中丛枝菌根真菌资源的取样调查,结果表明:发生根结线虫病害的土壤中AM真菌孢子数量较少,共鉴定出4属7种,其中,无梗囊霉属(Acaulospora)l 种,球囊霉属(Glomus)4种,多样囊霉属(Diversispora)1 种,类球囊霉属(Paraglomus)1 种,球囊霉属和多样孢囊霉属为设施蔬菜根围土壤中丛枝菌根真菌的优势属,沾屑多样孢囊霉D. spurcum、幼套球囊霉G. etunicatum、摩西球囊霉G. mosseae是此土壤中的优势种。这对于筛选抗根结线虫病害的优良菌种及其在设施生产中的应用具有非常重要意义。

Abstract: Abstract:The species diversity of arbuscular mycorrhizal fungi in the soil of different degree disease of the greenhouse vegetable root-knot nematodes, was investigated. Seven species belonging to four genera were isolated and identified from the rhizosphere soil sample, including 1species of Acaulospora, 4 species of Glomus, 1species of Diversispora, 1species of Paraglomus. Glomus and Diversispora were the dominant genera. Diversispora spurcum, Glomus etunicatum and Glomus mosseae were dominant species in the rhizosphere soil of the plant happening disease of the tree-note nematodes. It is helpful to screen out the better species of resisting disease of the eoot-knot nematodes and use for the greenhouse vegetable.
