杨树速生耐盐碱良品种‘辽胡2号杨’，雄株。其母本为‘小×胡’F1代杂种，父本为欧洲黑杨。在含盐量0.25%～0．4%、pH值9．0左右的中盐碱地上，18年生平均树高、平均胸径、单株材积比对照小美旱杨提高了10.1%，26.3%和115.6%。辽胡2号杨具有速生、耐中轻度盐碱、易繁殖、耐寒等优良特性。
楊樹速生耐鹽堿良品種‘遼鬍2號楊’，雄株。其母本為‘小×鬍’F1代雜種，父本為歐洲黑楊。在含鹽量0.25%～0．4%、pH值9．0左右的中鹽堿地上，18年生平均樹高、平均胸徑、單株材積比對照小美旱楊提高瞭10.1%，26.3%和115.6%。遼鬍2號楊具有速生、耐中輕度鹽堿、易繁殖、耐寒等優良特性。
양수속생내염감량품충‘료호2호양’，웅주。기모본위‘소×호’F1대잡충，부본위구주흑양。재함염량0.25%～0．4%、pH치9．0좌우적중염감지상，18년생평균수고、평균흉경、단주재적비대조소미한양제고료10.1%，26.3%화115.6%。료호2호양구유속생、내중경도염감、역번식、내한등우량특성。
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.
