南方红豆杉等3 种珍贵树种不同造林试验

Investigation on Survival Rate and Growth of Three Precious Tree Species

  • 摘要: 2013 年3 月,将1 年生南方红豆杉Taxus chinensis var. mairei,浙江楠Phoebe chekiangensis 和闽楠P.bournei无纺布袋苗种植于浙江省缙云县,进行村道路旁种植、杉木Cunninghamia lanceolata 采伐迹地造林和马尾松Pinusmassoniana 林下补植3 种造林方式的比较试验。2013 年10 月和2015 年2 月的调查结果表明,南方红豆杉当年成活率和3 a 保存率间没有明显的差异,但以迹地造林的平均地径和平均树高生长最低;浙江楠的当年存活率、3 a保存率以及平均地径和平均树高生长均是迹地造林最低,林下补植最高;闽楠当年存活率和3 a 保存率间没有明显的差异,但是3 a 保存率以及平均地径和平均树高生长均以迹地造林最低,路旁种植最高。试验结果表明,3 种珍贵树种均不适合迹地造林。

     

    Abstract: Plantation of 3 precious tree species like Taxus chinensis var. mairei, Phoebe chekiangensis and P. Bournei in March 2013 with their1-year container seedlings at roadside of village, cutting blank of Cunninghamia lanceolata and filling-up of Pinus massoniana stand. Investigationswere conducted in October 2013 and February 2014 on survival rate in the current year and conservation rate of 3-year tested tree species. The resultsshowed that survival and conservation rate of T.chinensis var. mairei had no obvious differences among different places, but average ground diameterand height growth of seedlings at cutting blank was the lowest. The survival and conservation rate, mean ground diameter and height growth of P.chekiangensis were the lowest in cutting blank, the highest in filling-up stand. The survival and conservation rate of P. Bournei had no obviousdifferences among different places, but conservation rate, mean ground diameter and height growth was the lowest at cutting blank, the highest atfilling-up stand. The investigation resulted that the tested three tree species were not suitable for afforestation at cutting blank, and P. Bournei was notsuitable for filling-up stand.
