| 中文摘要: |
| 解磷菌对于提高土壤磷元素的有效利用具有促进作用，而且对于土壤面源污染的防治也具有重
要意义。 通过对包头地区草坪土壤微生物的筛选，获得 3 株具有稳定解磷能力的解磷菌 P1、P2 和 P3，其中 P1
的解磷效果最佳；复合菌群组合试验结果表明，不同组合的解磷能力依次为 P1:P3跃P1:P2跃P1:P2:P3跃P2:P3，证实
P1 具有高效的解磷能力；分子鉴定结果表明，P1 是伯克霍尔德氏菌（Burkholderia sp.），说明该菌具有较大的应
用价值。 |
| 英文摘要: |
| Phosphate-solubilizing microorganism (PSM) can promote the effective utilization of soil phosphorus,
and play an important role in the control of non-point source pollution of soil. Three PSMs (P1, P2 and P3) with
stable phosphate -solubilizing ability were isolated from the turfgrass soil in Baotou, in which the solubilizing
phosphate ability of P1 was higher than that of the other two strains. The results about a series experiment on
composite bacteria system showed the order of phosphate-solubilizing ability was P1:P3 P1:P2 P1:P2:P3跃P2:P3,
which confirmed that P1 had high ability of dissolving phosphorus. The molecular identification showed that P1
belonged to Burkholderia sp., it had great application value in practice. |
