本文分析了大果圆柏的生物学和生态学特性,对育苗环节的苗圃地选择、种子采集、种子贮藏、种子处理、播种时间、播种方式、播种量以及苗木的后期管理进行了叙述。研究结果表明：1）沙藏是贮藏种子的最好方式,各项调查指标均优于其它贮藏方式;2）育苗过程中,应该特别注意夏季的控温和冬春两季的控湿措施;3）大果圆柏种子生长周期长,易受病虫侵害,种子发芽率不高,且种子存在生理后熟现象,无法打破休眠期,播种后次年才能发芽出土;4）大果圆柏苗木经过3个生长期后,可以出圃造林。

In this paper,analysis is made of the biological and ecological characteristics of Tibet juniper（Sabina tibetica）,and a description is given of the seedling nursery selection,seed collection,seed storage,seed treatment,sowing time,sowing methods,sowing amount and seedlings＇ final-period management.The results have shown that：1）Sand storage is the best way to store seeds.Its survey indexes are better than other storage methods;2） During seedling raising,special attention should be paid to the summer temperature control and the winter and spring humidity control;3）Tibet juniper seeds＇ growth cycle is long,therefore the seeds are vulnerable to disease and insect pest violations.The seed germination rate is not high.In addition,the seeds can germinate in the following year after sowing;4）Tibet juniper seedlings can be moved out of the nursery for afforestation after three growing periods.
