云南红豆杉裸根苗和容器苗造林对比试验

Experiment on Afforestation of Taxus yunnanensis with Container and Bare-root Seedlings

  • 摘要: 2012 年采用2 年生云南红豆杉Taxus yunnanensis 实生裸根苗和容器苗造林,连续3 a 观测其保存率和生长指标,研究裸根苗与容器苗造林成效。结果表明,两种苗的造林成活率均在95%以上,两者间无显著差异(P﹥0.05);1 年后裸根苗的苗高生长量与容器苗相比无显著差异,2 年后地径的增长量无显著差异,而造林成本低于容器苗;裸根苗造林有3 个月的缓苗期,在缓苗期加强水分管理以提高造林成活率;试验发现云南红豆杉的年生长周期可以划分为慢速生长期、快速生长期和生长基本停滞期3 个时期,依据生长周期的划分,在有灌溉的条件下,每年的3-4 月为裸根苗最适宜造林期。

     

    Abstract: Experiments were conducted on afforestation with 2-year container and bare-root Taxus yunnanensis seedlings in 2012 in Kunming,Yunnan province. Observations on conservation rate and growth traits had been implemented from 2012 to 2014. The result showed that the survivalrate of two kind seedlings was over 95%. The height increment of bare-root seedlings had no evident difference with that of container seedlings in2013, and ground diameter growth in 2014, but afforestation with bare-root seedling had lower cost. The experiment demonstrated that bare-rootseedlings had about 3 months for recovering, when good water management could increase survival rate of seedlings. The annual growth cycle of T.yunnanensis seedling could be divided into 3 stages, and the best time for bare-root seedling afforestation was March and April.
