摘　　要：采用单体钢管薄膜大棚、薄膜中拱棚、地膜和稻草覆盖三重保温措施,开展了普陀樟Cinnamomum japonicum var.chenii的强化育苗试验。结果表明,普陀樟采用三重保温技术育苗,其种子的平均场圃发芽率可达84.5%,比常规露地育苗高出10百分点以上,两者有极显著差异。三重保温育苗大大提高了早春育苗环境的气温和地温,促使普陀樟种子提早萌发,明显延长了苗木的生长期,并加速苗木生长,使苗木生长量成倍增长,1年生苗木的平均高生长可达75.6cm,是常规育苗的5.2~6.5倍,平均地径生长量可达1.24cm,是常规育苗的3.4~4.4倍。苗木生长均匀整齐,避免了劣级苗发生,大幅度提高了苗木产量和品质。Triple heat preservation measure including single pipe film greenhouse, middle-arch shed, plastic film and straw were adopted to conduct the seedling experiments of Cinnamomum japonicum var. chenii.The results indicated that with the triple heat preservation technology, the average field germination was 84.5 per cent, 10 per cent higher than the general open breeding, showing significant differences between the two ways of breeding. Moreover, the technology could greatly improve the air temperature and ground temperature for the seedling in early spring, promote the seedlings germination, prolong seedling growth period, and accelerate seedling growth. The average height growth of 1-year-old seedlings was 75.6 cm,which was 5.2 to 6.5 times that of the general breeding; the average diameter growth was up to 1.24 cm,3.4 to 4.4 times that of the general breeding. The heat preservation technology greatly increased the yield and quality of seedlings, avoided occurrence of low-quality seedlings, and brought significant economic benefits. The technology could be extended and applied in production.
