摘　　要：经过多年的研究 ,总结出了钻天柳种子收集、贮存、播种、扦插、移栽等技术措施。钻天柳适宜采种期为 7月末 8月初 ,种子千粒重 0 .30 3g ,秋播时间在 8月 10日以前。当年不播的种子可用快速封闭法贮存 ,春播时间在 5月 10日前后。播种量 1.2 5g/m2 。扦插时间在 7月 10日前后 ,插穗用 2 0 0mg/kg 1号生根粉处理 3h左右 ,扦插密度 4 80株 /m2 ,留床密度 50～ 80株 /m2 。移栽时坐水、平茬 ,成活率可达 90 %以上 ,第In this paper,seed collection,storage,sowing and cuttage,transplanting techniques of Chosenia arbutifolia were summarized after years experiments.Seeds should be collected at the end of July and beginning of August.The proper sowing time for new seeds is before Aug.10 and May 10 for old seeds with seed amount of 1.25g/m 2.Aided with root promoting chemicals,cuttings could be planted near July 10 with a density of 480 stem/m 2.More than 90% of cuttings with transplant density of 50～80 stem/m 2 could survive and would grow fast in next year.
