在北票半干旱地区开展了油松、樟子松和桧柏3种针叶树雨季容器苗造林试验,分别以春季裸根苗造林为对照,结果表明:在北票干旱和瘠薄立地条件下采用容器苗雨季造林,造林成活率超过95%,春季裸根苗造林,成活率仅为65.4%~74.6%。3个针叶树种容器苗雨季造林比对照能够明显提高苗高生长量、主根长、侧根多,与对照相比,油松苗高生长量提高38.97%,地径提高29.9%,主根长提高40.78%,侧根长提高40.76%;樟子松苗高生长量提高37.59%,地径提高31.69%,主根长提高16.89%,侧根长提高20.90%;桧柏苗高生长量提高27.49%,地径提高34.56%,主根长提高18.90%,侧根长提高35.71%。效果十分显著。
