摘　　要：试验表明,采用5种植物生长调节剂分别进行播前浸种和生长期喷叶处理,对油松容器育苗均有一定效果。其中以GGR6号的促进效果最显著,可使油松提早出苗2～3d,苗全期提前4～7d;当年高生长增加66.4%,地径生长增加71.8%,地上、地下部鲜重分别增加2.3倍和3.2倍。Five kinds of growth regulators of plant were used to treat seeds and seedlings during seeds soaking and seedling growing periods. The treatment were effective with regulator GGR6 significant to make seeds germinate 2～3 days ahead and have all seedlings period 4～7 days ahead. In the current year, height growth increased by (66.4%) and base diameter growth increased by (71.8%). Above-ground fresh weight increased 2.3 times while underground fresh weight increased 3.2 times.
