铅笔柏引种育苗与造林技术初步研究

辽宁省章古台从１９９４年开始引种铅笔柏，进行育苗与造林试验。试验结果认为，铅笔柏种子处理需要从１月下旬至４月下旬，约９０ｄ时间，发芽率较高；而从３月中旬至４月中旬开始处理的种子，因经过低温阶段时间短，故发芽率较低；铅笔柏越冬干梢与种源关系很大，美国南达科他州种源基本不受冻害，面安徽种源干梢较重，不宜直接引种；该树种在水肥充足条件下生长很快，４年生苗高达１．０５ｍ。

Research on seedling cultivation and afforestation techniques of introduced Sabina viginiana

Seedling cultivation and afforestation experiments of introduced Sabina viginiana were carried out in Zhanggutai of Liaoning province in 1994. The results showed that: seed treatment of Sabina viginiana was from the last ten days in January to the last ten days in April and took 90 days ,the germination rate was high; the germination rate of seeds treated from the middle ten days of March to the middle ten days of April was low,because the course of low temperature stage was short ,The relationship of dry-top of Sabina viginiana in winter with provenance was great,the provenance of South Dakota state in USA wasn' t damaged by cold ,but dry-top situation of Anhui provenance was very serious and wasn't suitable to be introduced directly Sabina viginiana grew fast under the condition of sufficient water and fertilizer ,height of 4 years seedling may reached 1.05m.
