为了促进沙地柏造林 ,根据塞罕坝机械林场的气候特点和立地条件 ,在春季对 1 5、2 0、2 5、30 cm4个长度段的沙地柏枝条进行了压条造林 ,催生愈合组织 ,夏季在不同立地类型的沙地上进行了移栽造林试验。结果表明 :沙地柏压条造林在枝条长度为 2 0 cm以上时 ,在草甸沙地、固定沙丘和阳坡山脚等不同立地条件下均能成活 ,适宜大面积推广造林。
In order to promote afforestation on Sabina vulgaris, according to the climatic characteristics and site conditions of Saihanba mechanical forest farm, 15-15,2 0,30 cm 4 lengths of Sabinatius cuspidata branches were planted in spring in order to promote the healing of tissues In summer, transplanting afforestation experiments were conducted on sandy land with different site types. The results showed that when the length of branches was more than 20 cm, the Betula platyphylla afforestation could survive under the different site conditions such as meadow sand, fixed sand dune and foot of Yangpo, which is suitable for large area afforestation.
