１９９４年将资源调查中得到的Ｇｌｏｍｕｓｍｏｓｓｅａｅ的４种不同菌株Ｓ（山东）、Ａ（美国）、９１（新疆）、９２（新疆）分别接种在土壤含水量分别为１５％，１０％和５％，并含磷矿粉的盆栽大豆（Ｇｌｙｃｉｎｅｒａｘ）上，以不接种孢子的为对照，经测定，３个水分条件下供试的４个菌株都有侵染，其中Ｓ和９１菌株以１０％水分处理侵染率最高，Ａ和９２菌株以１５％处理侵染率最高；在水分充足时，大豆磷含量菌根株比非菌根株显著增加，其中接种９１的植株在各种水分条件下，含磷量都高；菌根株的萎蔫系数均显著低于非菌根株，且在５％和１５％水分条件下，接种Ｓ和Ａ植株萎蔫系数显著低于接种９１和９２的植株。
In 1994, four different strains of Glomus mosseae, S (Shandong), A (USA), 91 (Xinjiang) and 92 (Xinjiang) obtained from the resource survey were respectively inoculated into soil with 15%, 10% and 5% And phosphate-containing potted soybean (Glycinerax) on the non-inoculated spores as control, determined under the three water conditions were tested four strains were infected, in which S and 91 strains treated with 10% water The infection rates of A and 92 were the highest at 15% treatment. When sufficient water was available, the phosphorus content of soybean mycorrhizal plants increased significantly compared with that of non-mycorrhizal plants, in which the inoculation of 91 plants under various water conditions, the phosphorus content The coefficient of wilting of mycorrhizal plants was significantly lower than that of non-mycorrhizal plants. Under the conditions of 5% and 15% moisture, the coefficient of wilting of inoculated plants S and A was significantly lower than those of plants 91 and 92.
