Study on the Growth of Taxus wallichiana var.mairei in Pinus massoniana Forest of Different Densities
In this paper,experiments were made on planting of Taxus wallichianavar.Maireiin Pinus massonianaforest of different densities to study the effects of mixed forest on the growth of Taxus wallichianavar.Mairei.The results showed that 3 years after the planting,the tree height,basal diameter,tree height increment,basal diameter increment and survival rate of Taxus wallichianavar.Mairei were the highest in the Pinus massonianaforest at density 0.7,followed by density 0.6 and 0.8,much better than the other densi-ties.The Taxus wallichianavar.Maireitrees planted for 3 years in the Pinus massonianaforest of 5 densities could be divided into 3 groups using cluster analysis,with Group A at density 0.7 having the highest growth rate,Group B at densities 0.6 and 0.8 having a me-dium growth rate,Group C at densities 0.4 and 0.5 having the slowest growth rate.
