Investigation on Survival Rate and Growth of Three Precious Tree Species

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.
