安徽滁州地区15个杨树无性系造林试验

Afforestation Contrast Test of 15 Poplar Clones in Chuzhou Area,Anhui

将15个杨树优良无性系在安徽省江淮丘陵地区的滁州市沙河镇进行了造林对比试验,通过9a的跟踪调查及数据分析,结果表明:189最具生长优势,9 a生胸径为31.98 cm,树高为22.33 m,单株材积为0.58578 m3,分别比对照A2(中涡1号)高出28.5%,11.7%和77.7%。本试验为安徽省江淮丘陵地区杨树人工林造林提供了无性系选择依据。

Afforestation contrast tests of 15 poplar clones were carried out in Shahe Town of Chuzhou City, which was one of Jianghuai hilly regions in Anhui. Through survey and data analysis, the results showed that 189 had the greatest growth advantage, 9-year-old DBH, height and stem volume were 31.98 cm, 22. 33 m, and 0. 58578 m^3 ,respectively, increased by 28.5%, 11.7% and 77.7% as compared with control （A2）.
