【摘要】 为探讨解决干旱山区造林保存率低下的问题 ,在兰州市北山干旱山区的徐家山试验基地相同立地条件下 ,以侧柏作为试验树种进行卡氏、干旱造林方式对比试验。结果表明 :卡氏造林的成活率和保存率明显高于干旱造林 ,3年生卡氏造林的成活率和保存率均达 93%以上 ;采用卡氏造林的苗木高生长、地径生长、发枝数、新梢生长量均明显高于干旱造林 ,二者差异性显著更多还原

【Abstract】 Experiment of Karist’s forestation was conducted in the arid area of lanzhou to raise survival rate of this area. The result indicated that the survival rate of Karist’s forestation was higher than the conventional forestation. The survival rate of 3 annual arborviate was above 93%.The height and diameter growth ,new branch numbers and the new branch length of the Karist’s forestation was higher than the conventional forestation obviously.更多还原
