摘要：

The soil cores of a salt tolerant grass D. fusca Linn. Beauv. commonly grown in the saline-sodic area of Pakistan showed high nitrogenase activity. High input values of N, up to 127 kg/ha per 100 days were obtained by extrapolating the acetylene reduction values. Anabaena variabilis was isolated from the soil, and isolated algae showed values of nitrogenase activity and 15N incorporation comparable to those of A. cylindrica. Enrichment assays resulted in recovery of several N2-fixing bacteria. Some characteristics of the most efficient isolate were studied, which suggests that the isolate belongs to genus Azospirillum.
