2000年3月~2001年2月对黄河三角洲盐碱土壤中5种优势植物柽柳(Tamarix chinensis)、芦苇(Phragmites communis)、碱蓬(Suaeda glauca)、獐毛(Aeluropus littoralis var. sinensis)和刺儿菜(Cirsium setosum)根围内丛枝菌根(arbuscular mycorrhiza, AM)真菌进行了长期定点调查。结果表明,AM真菌在这5种植物根围土壤内都有分布,但多样性较低,尤其在冬季,AM真菌种的丰度和孢子密度分别比夏季降低了18.0%和61.6%。不同深度土层中AM真菌的分布存在诸多差异。

Arbuscular mycorrhizal (AM) fungi in the rhizosphere of five dominant plants Tamari xchinensis , Phragmites communis , Suaeda glauca , Ael uropuslit toralis var. sinensis and Cirsium setosum grown in saline-alkaline soil of the Yellow River Delta were investigated on fixed sample sites from March 2000 to February 2001. AM fungi in the rhizosphere of the five plants were isolated. The result indicated that the diversity of AM fungi in saline-alkaline soil was quite low , especially in winter. Species richness and spore density were decreased by 18.0 % and 61.6 % , respectively , relative to those in summer. Differences were also observed in the dist ribution of AM fungi in different layers of soil.
