马鞍山江滩3个杨树无性系的生长比较
Comparisons to the three poplar clones planted on riparian area of Yangtse river, Ma'anshan city
摘要
Abstract
In order to select the poplar clones which are suitable to the riparian area conditions of Yangtse river, the mixed plantations of three poplar clones (I-72, I-69 and ' Zhonglin46') were investigated in Ma' anshan city, Anhui province. The result showed that the diameter at breast height (DBH), height and volume of poplar ' Zhonglin46' were significantly different from poplar I-72 and poplar I-69. The volume of poplar 'Zhonglin46' in 8 years old was 0.199 m'per tree, however, the volume of poplar I-72 and poplarI-69 was 0.499 m3 per tree and 0.360 m3 per tree, respectively. The DBH of poplar I-72 was larger than that of poplar I-69, but the height of both poplar I-72 and poplar I-69 was similar to each other. These results indicated that the poplar ' Zhonglin46' was not suitable to plant on the beach land of Yangtse river. Although both of the poplarI-72 and poplar I-69 could be used to plant on the beach land, the DBH and volume growth of poplar I-72 were higher than that of poplar I-69 when the planting space was larger.关键词
