| 摘 要： | 研究盆栽条件下,接种不同丛枝菌根真菌（arbuscular mycorrhizal fungi, AMF）种类对生姜不同生育时期农艺性状的影响及其在生姜根内的定殖情况。采用生姜组培苗,于幼苗期分别接种12株AMF进行生姜农艺性状比较试验,在温室盆栽接种后每隔30 d对生姜根系进行取样分析,比较菌根侵染率、侵染强度和丛枝丰度的大小,以观察不同AMF菌株对生姜苗的侵染动态。结果表明,所有接种AMF组的生姜植株,其生长量均高于空白对照组。结合不同菌株在根系的侵染率,筛选出生姜AMF优势种类为：细凹无梗囊霉（Acaulospora scrobiculata）、网状球囊霉（Glomus reticulatum）、隐形球囊霉（Paraglomus occltum）、摩西球囊霉（Glomus mosseae）。说明苗期接种这4个优势菌种,能够促进生姜生长,是适宜生姜生长的优良AMF菌株。

| Abstract: | An experiment was conducted to analyze the effects of arbuscular mycorrhizal (AM) fungi on the growth of ginger (Zingiber officinale Roscoe) under greenhouse conditions. Ginger plantlets were inoculated with 12 different AM species, and the agronomic characters, the rate of colonization, infection intensity and arbuscular abundance were analyzed in every 30 days after inoculation. The results showed the ginger plantlets inoculated with AM fungi grew better than the ones without AM fungi. The dominant strains of AM fungi were Acaulospora scrobiculata, Glomus reticulatum, Paraglomus occltum and Glomus mosseae according to the growth simulation and infection in roots. It suggests that the inoculation of the four dominant strains improved the growth, yield and quality, and further research is needed to develop dominant strains. |
