Abstract: The forest culture of 1-year plantation of Taxus chinensis var. mairei in different grades with different treatments was studied. The results showed that the tree height and diameter reached their growth peaks and the first height growing-peak was higher than the second while the first diameter growing-peak was lower than the second; classⅠseedlings had a better result than class Ⅱ; the survival rate and growth of seedlings treated with basal dressing were higher than those of seedlings without basal dressing; the optimum growth temperature of seedling was 23~30℃. Based on the analysis of variance, the regressive equations between the height and diameter, branch number were also built.

Key words: Taxus chinensis var. mairei, increment, survival rate, analysis of variance
