为研究高效解磷细菌多噬伯克霍尔德氏菌（ Burkholderia multivorans） WS-FJ9对杨树的促生机制，探讨了接种WS-FJ9菌株对NL-895杨磷素代谢、氮素代谢、可溶性蛋白含量及根系活力的影响，从养分代谢和根系活力的角度阐明WS-FJ9菌株对杨树的促生机制。结果表明，接种WS-FJ9处理能显著提高NL-895杨磷素含量、增加硝态氮和可溶性蛋白的含量，增强硝酸还原酶活性和根系活力，从而促进了杨树的生长。
為研究高效解燐細菌多噬伯剋霍爾德氏菌（ Burkholderia multivorans） WS-FJ9對楊樹的促生機製，探討瞭接種WS-FJ9菌株對NL-895楊燐素代謝、氮素代謝、可溶性蛋白含量及根繫活力的影響，從養分代謝和根繫活力的角度闡明WS-FJ9菌株對楊樹的促生機製。結果錶明，接種WS-FJ9處理能顯著提高NL-895楊燐素含量、增加硝態氮和可溶性蛋白的含量，增彊硝痠還原酶活性和根繫活力，從而促進瞭楊樹的生長。

The aim of this research was to study the growth-promoting effects of Burkholderia multivorans WS-FJ9 on poplar.To this end,the effects of inoculating strain WS-FJ9 on phosphorus metabolism ,nitrogen metabolism,contents of soluble protein and root activity of poplar were investigated .The growth-promoting mechanism of strain WS-FJ9 on poplars was illuminated from the perspective of nutrient metabolism and root activity.The results showed that inoculating strain WS-FJ9 could significantly improve the contents of phos-phorus ,nitrate nitrogen and soluble protein ,and enhance nitrate reductase activity and root activity of NL-895 poplar,thus the growth and development of poplar were promoted .
