摘　　要：以Glomus velsiforme（GV）、Glomus mosseae（GM）和Glomus intraradices（GI）3种丛枝菌根菌及其混合菌种GM＋GV、GM＋GI、GV＋GI和GM＋GV＋GI接种黄瓜幼苗，进行菌根化育苗，研究菌根化育苗对黄瓜的生长发育、产量和品质的影响．结果表明，接种的丛枝菌根菌均能与黄瓜幼苗根系形成菌根，侵染率高达41．74％～55．69％．其中，GV、GM、GM＋GV、GM＋GV＋GI和GV＋GI是黄瓜的优势菌种，与对照相比，壮苗指数提高了58．14％～123．6％，前期产量增加了21．71％～37．87％，总产量增加了19．72％～34．41％．接种GM＋GV和GV＋GI处理可显著地提高黄瓜果实中Vc的含量，分别比对照提高了22．84％和21．95％；接种GV、GV＋GI和GI处理可显著提高黄瓜果实中可溶性糖含量，分别比对照提高了13．79％、10．20％和8．25％；接种GV和GM＋GI处理黄瓜果实中的氨基酸含量，分别比对照提高了47．66％和23．19％，蛋白质含量提高了17．67％-34．79％．In this paper, arbuscular mycorrhizal fungi （AMF） Glomus versiforme （GV） , Glomus mosseae （ GM ） , Glomus intraradices （GI） and their mixtures were applied to inoculate plastic greenhouse Cucumis sativus seedlings to investigate the effects of AMF on C. sativus growth, development, yield, and quality. The results showed that all test AMF could form mycorrhiza with cucumber roots, and the infected rate reached 41.74% - 55.69%. Compared with the control, treatments GV, GM, GM ＋ GV, GM ＋ GV ＋ GI and GV ＋ GI enhanced the healthy seedling index by 58.14% - 123.6% , and increased early yield by 21.71%-37.87% and total yield by 19.72%-34.41%. AMF also improved fruit quality. The Vc content of cucumber fruit increased by 22.84% and 21.95% in treatments GM ＋ GV and GV ＋ GI, soluble sugar content increased by 13.29%, 8. 25% , and 10. 20% in treatments GV, GI and GV ＋ GI, and amino acid content increased by 47.66% and 23. 19% in treatments GV and GM ＋ GI, respectively, while soluble protein content increased by 17.67% -34. 29% in all AMF treatments. The results suggested that AMF inoculation could significantly promote the seedling growth of cucumber and improve its fruit quality, and the effects differed with different AMF and their combinations.
