| Abstract: | This paper reports the result of a four year research on growth response of young Larix kaempferi plantations to fertilization.The growth response of Larix kaemperi was significant to the application of NPK.The increments growth of tree height,basal diameter and crown width of the treatment plots were higher than that of the check plots.Though it was no remarkable in the first year of planting ,the effects of fertilization was clear in the second year and last to the forth year.There was no obvious difference between various NPK level treatments. |
