采用两种不同的ＶＡ菌根真菌Ｇ．ｍｏｓｓｅａｅ和Ｇ．ｖｅｒｓｉｆｏｒｍｅ，在施盐量分别为０，１．０，１．５和２．０ｇ／ｋｇ土的盆栽条件下，研究ＶＡ菌根真菌对玉米生长发育、根系活力的影响及机理。结果表明，接种Ｇ．ｍｏｓｓｅａｅ能显著促进植株生长，对根系活力的促进作用达到极显著水平，接种Ｇ．ｖｅｒｓｉｆｏｒｍｅ促进生长作用不显著，仅在低盐浓度条件下对根系促进显著。说明玉米在盐分胁迫条件下，通过ＶＡ菌根真菌增强根系活力，从而提高玉米的耐盐能力，Ｇ．ｍｏｓｓｅａｅ对玉米效应最佳。
Two different VA mycorrhizal fungi were used. mosseae and G. versiforme, the effects of VA mycorrhizal fungi on the growth and root activity of maize and its mechanism were studied under pottage of 0, 1.0, 1.5 and 2.0 g / kg soil salt. The results showed that inoculation G. Mosseae can significantly promote plant growth, the promotion of root activity reached a significant level, inoculation G. Versiforme promote growth is not significant, only under low salt concentration conditions on the root promotion significantly. Explain corn under salt stress conditions, by VA mycorrhizal fungi to enhance root activity, thereby enhancing the salt tolerance of corn, Mosseae has the best effect on corn.
