Abstract: The new fast-growing and salt-alkali enduring poplar of Populus simonii×P.euphratica 'Liaohu2', Male plants, was created form the cross between mother plant F1 of hybrids of P.×P.euphratica and father plant P. Nigra. Compared with Populus ×xiaozuanica 'poplar', the indexes of the average tree height, DBH and individual volume of P. simonii×P.euphratica 'Liaohu2'18-years tree increased by 10.1%,26.3% and 115.6% respectively growled in saline-alkali land with salinity 0.25%-0.4% and pH 9.0. Populus simonii×P.euphratica 'Liaohu2' had excellent characteristics: fast-growing, salt-alkali enduring, easy reproduction and cold-resistant.
