采用土培试验研究了水分胁迫条件下接种ＶＡ 菌根真菌Ｇｌｏｍ ｕｓｍ ｏｓｓｅａｅ，Ｇ．ｓｐ．和Ｇ．ｃａｌｅｄｏｎｉｕｍ 对玉米营养生长和抗旱性的影响。结果表明，水分胁迫严重抑制了植株的生长，但对ＶＡ 菌根真菌侵染能力影响不大。接种ＶＡ 菌根真菌不仅提高了植株磷和总氮含量，而且明显改善了植株的水分状况；接种株多种光合参数优于对照株，显著提高了接种株叶片的光合速率，增加植株干物质量，增强了玉米的抗旱性。３ 种真菌中，以Ｇｌｏｍ ｕｓ ｍ ｏｓｓｅａｅ的接种效果最好。
A soil culture experiment was conducted to study the inoculation of VA mycorrhizal fungi Glomusm osseae, G under water stress. sp. And G. Effect of Caledonium on the Nutritional Growth and Drought Resistance of Corn. The results showed that water stress seriously inhibited the growth of plants, but had little effect on the mycorrhizal fungal infection ability. Inoculation of VA mycorrhizal fungi not only increased plant phosphorus and total nitrogen, but also significantly improved the water status of the plants. The photosynthetic parameters of the inoculated plants were better than that of the control plants, significantly increasing the photosynthetic rate of the inoculated plants and increasing the plant dry matter, Enhanced maize drought resistance. Among 3 kinds of fungi, Glomus m osseae had the best inoculation effect.
