以北抗、08等系列的12种引进速生杨品种为研究对象,调查幼苗期成活率、保存率、胸径、新梢长,运用隶属函数法对12种速生杨幼苗在乌兰布和沙漠东北部的适应性进行综合评价。结果表明:速生杨各品种成活率在84.12%~100%之间,其中成活率较高的为08-01,08-07和北抗16-27;保存率在68.42%~100%之间,较高的为08-07、北抗16-27和08-01;胸径生长量在0.13~1.35cm范围内,较高的为08-09,08-03,08-01;新梢生长量在19.39~103.88cm范围内,较高的为北抗16-27、北抗16-8和08-03。通过隶属函数值进行排序,08-01、北抗16-27和08-09等3种速生杨品种幼苗期在乌兰布和沙漠东北部的生长适应性较好,可以作为该区防护林造林优良品种。
12 varieties of introduced poplar were used as research object to investigate the survival rate, preservation rate, diameter at breast height and length of new shoots in the series of north anti-08 and other series. The seedlings of 12 kinds of poplar were grown in the north of Ulan Buh Desert Department of adaptability to conduct a comprehensive assessment. The results showed that the survival rate of Populus trichocarpa varied from 84.12% to 100%. The highest survival rate was 08-01,08-07 and the second was 16-27. The preservation rates ranged from 68.42% to 100% Higher for 08-07, North anti-16-27 and 08-01; DBH growth ranged from 0.13 to 1.35 cm, higher for 08-09, 08-03 and 08-01; 19.39 ~ 103.88cm range, the higher North anti-16-27, North anti-16-8 and 08-03. According to the rank of membership function, the growth adaptability of three poplar varieties (08-01, North Anti-16-27 and 08-09) in the seedling stage of the Ulanbuh Desert was good, which could be used as the good plantation of the shelterbelt Variety.
