摘　　要：臭椿是呼和浩特市市区引进栽培的一种优良园林绿化树种,为实现该树种就地育苗栽植,对其育苗技术进行了研究。本文采用田间对比实验法,主要对不同的覆膜处理和种子贮藏时间与臭椿播种育苗的出苗和生长关系进行了研究,结果表明:覆膜明显提高了种子出苗率和苗木生长量,出苗率、地径、苗高比对照分别提高了31.34﹪、5.0mm、12.7cm;贮藏0.5a比贮藏1.5a的种子出苗率、地径和苗高分别提高了17﹪、4.3mm和22.7cm。Ailanthus altissima is an excellent ornamental trees which is introduced to cultivation in hohhot.The effects of cover film and storage time on germination and growth of Ailanthus altissima seed were studied in field comparative experiments in this paper and cultivation techniques were studied in order to achieve the local nursery planted trees.The results showed that： cover film significantly increased the seed germination and growth of seedlings,germination percentage,ground diameter,height increase 31.34%,5.0mm,12.7cm separately compared with the control;Germination percentage,ground diameter,height increase 17﹪、4.3mm和22.7cm separately storage 0.5 years compared with storage 1.5 years.
