| Abstract: | A study was conducted to determine the effect of varied additional fertilizing treatmens of N fertilizer on growth of Larix olgensis sowing seedlings with split-plot experiment design.Results show that fertilization times and amount of N fertilizer significantly affected the height growth of and basal diameter growth of sowing seedlings.Five applications with an interval of 11 days had a significant effect on height growth of seedlings.For fertilizing amount,application of 36.3 g·m-2 N stimulated the growth of basal diameter apparently.However,the fertilization efficiency of 36.3 g·m-2 N supply relevant to seedling height growth and basal diameter was lower than that of 13.7 g·m-2 N supply and the control. |
