摘　　要：通过对兴安圆柏容器大苗培育技术的试验研究,结果表明:苗木装袋前用生根粉处理苗木对育苗成活率影响不明显;春季装袋和秋季装袋均可,春季装袋不需防寒,程序简化,秋季装袋需要防寒,但生长量大;不同营养土对兴安圆柏容器育苗成活率影响不大,均能达到97%,但其对兴安圆柏生长量影响较大,以营养土配方B(70%的苗圃地土,15%森林草炭土,15%的腐熟农家肥)对苗木生长的促进作用最好,成活率达98%,最长枝平均生长量13.5cm,平均高生长量为10.5cm。Cultivation experiments of large container seedlings of Sabina davurica were conducted .Result shows that the effects of ABT rooting powder on survival rate of seedlings is not significant before bagging ;bagging can be conducted in spring or autumn;bagging needs no cold‐proof in spring ,with simple procedures .Bagging needs cold‐proof in autumn ,with large growth;the effect of different nutritive soil on survival rate of container seedling‐raising of Sabina davurica is little ,all can reach 97% ;different nutritive soil affect greatly on the growth of Sabina davuri‐ca ;promotion of the formulation B of nutritive soil (70% nursery soil ,15% peat soil in the forest ,15% mature ma‐nure) on growth of seedlings is optimal ,survival rate being 98% ;the mean growth of the longest branch is 13 .5 cm , the mean height growth being 10 .5 cm .
