摘　　要：[目的]研究中华红叶杨在西藏快速繁育的方法。[方法]研究不同覆膜厚度对中华红叶杨成活率、苗高、侧根的影响。[结果]应用地膜覆盖进行红叶杨扦插育苗提早展叶5 d,扦插成活率达87%,比不覆膜的苗高增长92%,地下部分平均侧根增长60%,侧根数增加80%。[结论]红叶杨在西藏林芝地区宜采用覆膜扦插。[Objective] The aim of the study was to seek a good rapid breeding of Populus deltoids cv.in Tibet.[Method] Populus deltoids cv.was used to study the effect of different plastic film mulch application on survival rate,height and ground diameter[Result] The leaf of Populus deltoids cv.which used in the film cutting bud opening phase was ahead of 5 days,the young seedlings could survive at the rate of 87%,the height growth of 92% than not film mulching,the underground part of the average lateral root length increased 60%,80% increase in the number of lateral roots than not film mulching.[Conclusion] Populus deltoids cv.was suitable to use film cutting in Linzhi of Tibet.
