摘 要:
针对内蒙古大青山干旱阳坡的特点,采用油松3年生容器苗、沙棘和山杏2年生裸根苗植苗推广造林66.67 hm^2,平均造林成活率达90.6%,保存率在85%以上。在造林后4年,林分平均高为84.3 cm,平均基径达1.6 cm,当年高生长量平均达41.3 cm,对林地土壤肥力的改善十分明显。因此得出：在大青山干旱阳坡推广造林,应以油松、山杏、柠条等抗旱树种为主,采取小规模的鱼鳞坑和水平沟整地方式,造林以春季为主。采取株间混交方式,株行距2 m×3 m和2 m×4 m;混交比例以油松50%,沙棘、山杏为50%。造林当年的7-8月份松土除草1-2次,并加强对鼠害和兔害的防治工作。[著者文摘]

Abstract:
According to characteristic of dry adret in Daqing Mountains, selected suitable tree species,used affoirestion technique of anti - drought ,66.67 hm^2 of forest for conservation of water supply were planted by use of 3 - year -old container seedlings of Pinus tabulaeformis Cart. ,2 -year -old seedlings of Hippophae rhamnoides L. and Prunus armeniaca var. ansu Maxim. Average survival rate was 90.6, preserved rate of plantation was more than 85%. 4 years after planting, average height of forest stand is 84.3 cm,root diameter is 1.6 cm,average current increment of height is 41.3 cm.[著者文摘]
