This study was carried out to investigate the influence of shading pretreatment and planting density on the periodic needle growth in fresh and dry weight.
1) The fresh and dry weight growth of needles per seedling increased with light intensity and decreased with increase of planting density. The best growth of needles in fresh weight and dry weight appeared during the period from May to June. 2) The contribution rates to the growth of fresh and dry weight of needles  were 1.9% and 5.1% in light intensity, 3.6% and 3.2% in planting density and 83.7% and 75.6% in growth period, respectively. 3) For the three factors, i.e. shading, planting density and growth period, all the interactions between any two factors, and among the three factors in the fresh and dry weight growth of needles per plant were significant.
Key words: shading, planting density, growth period, fresh weight, dry weight, needle
