| 摘 要： | 选用从内蒙古锡林郭勒天然草原冰草（Aqropyrom cristatum）根际分离获得的固氮菌株BC2进行室内接种效果研究。结果表明,接种BC2后冰草植株干质量增加，整个体系中固氮量比未接种冰草增加42.55 mg/kg；土壤灭菌后接种效果更为明显，体系总氮含量增加80.95 mg/kg，是未灭菌处理的近2倍；同时增加碳源于土壤可提高BC2的固氮效率。

| Abstract: | An experiment was conducted to determine the effect of inoculation of non-symbiotic azotobacteria BC2 isolating from wheatgrass(Agropyrom cristatum) on the growth and fixing nitrogen.The results of this study showed that BC2 inoculation increased the dry weight of wheatgrass and nitrogen-fixing capability with 42.55 mg/kg in the entire system when compared to the control.The effectiveness of inoculation was better due to soil sterilization and the total nitrogen content of sterilized soil with 80.95 mg/kg w... |
