大荔县杨树扦插造林技术

Propagation Technology of Poplar in Dali County

在实践和调查测定基础上,研究了沙兰杨、波兰15号杨、欧美108号杨、中林46速生杨等4个易生根杨树品种在大荔县扦插造林技术及其与植苗造林技术在幼树生长、病虫害发生、造林成本等方面的差别,结果为扦插造林幼树生长旺盛,树形好,幼树溃疡病感染率和钻心虫危害率较低,造林成本降低,值得在大荔县及环境条件相近地区推广。提出了品种选择、造林密度、修枝等速生杨扦插造林技术。

Fast growing poplars like Sacrau poplar,Populus ×canadensisMoench cv.Polska 15,Euramerican poplar No.108 and yangshujiaxi-zhonglin 46 were compared in terms of planting cost,pest control and growing through experiments with cutting technologies and seedling afforestation.The result showed that cutting makes the tree growing prosperously and having agood shape,with lower rate of infection with pest and lower cost of planting,which is worth application in Dali County.Key technologies of cutting are the selection of varieties,density of planting and pruning.
