Determination of annual Xinjiang poplar Wutun poplar under the same conditions, the growth indica-tors, the results show that the Wutun poplar implanted in 4436, 342 died, Wutun poplar's survival rate was 92.3%, while Xinjiang poplar implanted in 4399, 513 died, Xinjiang poplar survival rate was 88.3%.Through the investi-gation of Wutun poplar, and Xinjiang poplar plant height, diameter, diameter at breast height and found that Wutun poplar both plant height, basal diameter, diameter at breast height of these growth indicators are excellent and the Xinjiang poplar, so it can be concluded in the same habitatunder Wutun poplar faster than Xinjiang poplar growth rate, the overall growth is relatively stable, the resistance of fast-growing Wutun poplar introduction to the southern border is feasible.%通过对一年生的新疆杨与吴屯杨在同一条件下的生长指标测定，结果表明，吴屯杨共植入4436株，死亡342株，吴屯杨的成活率为92.3%；而新疆杨共植入4399株，死亡513株，新疆杨的成活率为88.3%.通过调查吴屯杨和新疆杨的株高、地径、胸径，发现吴屯杨无论是株高、地径、胸径这些生长指标都优与新疆杨，因此在同一生境下吴屯杨比新疆杨生长速率更快，整体生长比较稳定，抗逆性速生吴屯杨引种至南疆具有可行性.
