• 英文摘要： Different species of blue-green algae(BGA) isolated from local rice fields, includ-ing Anabaena, Nostoc, Anabaenopsis, Cylind-rospermum, Scytonema, Calothrix, and Hap-alosiphon, were inoculated into submergedsoil. Among them, Anabaena HA501 andNostoc HN501 had better ability to establishtheir population in the water-flooded soil. Ingeneral, the BGA was more stable and easyto establish their population on the wettedsoil than in the flooding soil. The nitrogen-fixing activity of the BGA-inoculated soilwas enhanced when the soil was supplymentedwith phosphate or rice straw. The resultalso indicated that a BGA with high nitrogen-fixing activity in the laboratory conditionmay not be the good strain for the use infield-application, because it may not be ableto establish its population.
