秃杉第1代无性系种子园营建技术研究

Study on the Establishing and Managing Techniques of the First Generation of Taiwania flousiana Gaussen Clone Seed Orchard

总结了德化葛坑国有林场2009年营建的秃杉第1代无性系种子园的营建技术,并于2012年5月对建园效果进行调查分析。结果表明:砧木保存率为89.4%,嫁接保存率为86.9%,嫁接植株的正冠率为82.3%;2010年嫁接的植株平均树高、地径和冠幅分别为1.2 m、3.1 cm、0.8 m,最优株树高1.8 m、胸径1.6 cm、冠幅1.3 m。

The first generation of Taiwania flousiana Gaussen clone seed orchard was established at Gekeng Forest Farm,Dehua,Fujian Province in 2009.The effect of seed orchard was investigated in May,2012.The results showed that the preserved rate of rootstocks reached 89.4%;the preserved rate of grafted trees attained 86.9%;the straight crown rate of grafted trees attained 82.3%;the mean height,ground-diameter and crown width of trees grafted in 2010 was 1.2m,3.1 cm,and 0.8m,and the height,DBH and crown width of the best tree were 1.8m,1.6 cm,and 1.3m.
