摘要:
 选用适宜的造林整地技术是改善土壤条件，提高人工造林成活率的重要方法。以5种造林穴大小，按照完全随机区组试验设计营建的三倍体毛白杨人工林为研究对象，经过5 a的田间试验，研究了造林穴大小对三倍体毛白杨生长的影响。结果表明，造林穴大小对1年生、3年生、4年生以及5年生三倍体毛白杨胸径生长量影响显著；对1年生以及3年生的三倍体毛白杨树高生长量影响显著；对1年生、3年生以及4年生的三倍体毛白杨材积生长量影响极显著。就生长量而言，如果选择三倍体毛白杨开展超短轮伐经营（轮伐期1~3 a），则很有必要考虑造林穴大小对三倍体毛白杨生长的影响。如果选择三倍体毛白杨开展短轮伐经营（轮伐期5 a以上），则可以不考虑造林穴大小对三倍体毛白杨生长的影响，建议选择60 cm×60 cm×60 cm大小的造林穴为宜。
Abstract:
 Selecting appropriate site preparation technique before establishing plantation is a good way to improve soil condition and seedling survival.An experiment was conducted to determine the effects of planting hole size on the growth of triploid clones of Populus tomentosa based on a five-year-old trial established in a randomized block design with three block replicates.The results indicated that the effects of planting hole size were significant on the diameter at breast height of 1-,3-,4-,and 5-year-old trees.It was significant on the tree height of 1-and 3-year-old trees.The effects were most significant on the stem volume of 1-,3-,and 4-year-old trees,indicating that if an intensive short-rotation plantation was built the effects of the hole size must be taken into account to obtain higher yield,on the contrary,if a conventional short-rotation (such as 5 years) plantation was built,the effect could be ignored.Planting hole with a size of 60 cm×60 cm×60 cm was suggested to use in planting practice.
