摘要
为湘南紫色岩地筛选适宜造林树种 ,对三倍体毛白杨进行引种造林试验 ,结果表明 :三倍体毛白杨的造林成活率 10 0 %,保存率 98%;生长良好 ,截止 6月 2日平均树高为 2 86.3cm(增量 87.3cm) ,平均胸径为 2 .0 1cm(增量 0 .2 3cm)。其中以 96号表现最好 ,73号表现最差。为使植株生长良好 。
In order to introduce and cultivate Populus to mentosa triploid in shale area of South Hunan Province, we made use of the collegial convenience,situated in shale area, and studied its relevance to the research. Observations indicated that by the second of June, in 2002 its survival rate and the preserved rate of afforestation is respectively 100% and 98%,growth of mean height and increase is 286.3?cm and 87.3 cm,growth of mean diameter at breast height and increase is 2.01cm and 0.23?cm,of which at present the best is 96(variety) and the worst is 73(variety).In addition,when cutted we should pay attention to the position of bud and protect its apical bud for better growth.
