在温室盆栽条件下，研究了不同碱化度土壤中盐生植物芨芨草（ＡｃｈｎａｔｈｅｒｕｍｓｐｌｅｎｄｅｎｓＮｅｖｓｋｉ）和非盐生植物高羊茅（ＦｅｓｔｕｃａｅｌａｔａＫｅｎｇ）生长和丛枝菌根（ＡＭ）的发育状况。结果表明：这两种植物均能被ＡＭ菌感染；碱化度小于１０％的非盐碱土壤中高羊茅比芨芨草的菌根侵染率高。而碱化度大于２０％的盐碱土壤中，后者的菌根侵染率则显著大于前者。碱化度越高的土壤对菌根发育的抑制作用越大、菌根发育越差。不同碱化度土壤中菌根生长发育状况和功能因ＡＭ菌种的不同而存在差异，其中以Ｇｌｏｍｕｓｍｏｓｅａｅ３２和Ｇｉｇａｓｐｏｒａｒｏｓｅａ较耐盐碱。接种ＡＭ菌能显著提高芨芨草和高羊茅的生长量。
Under greenhouse conditions, the growth of halophytes Achnatherumsplendens Nevski and FestucaelataKeng in different alkalinity soils and arbuscular mycorrhizal (AM) development were studied. The results showed that both of the two plants could be infected by AM fungi. In non-saline soils with less than 10% alkalization degree, tall fescue had higher mycorrhizal infection rates than Achnatherum splendens. The alkalinity of more than 20% of saline-alkali soil, the latter’s mycorrhizal infection rate was significantly greater than the former. The higher the degree of alkalinity of the soil on the inhibition of mycorrhizal growth, the worse mycorrhizal development. The growth and development of mycorrhizal in different degree alkalized soil were different due to different AM strains. Glomus moseae32 and Gigasporarosea were more tolerant to salt and alkali. Inoculation of AM bacteria can significantly increase the growth of Achnatherum splendens and tall fescue.
