조림 묘령에 따른 고로쇠나무 조림목의 생장 및 수관경쟁 특성

This s tudy was conducted to understand the e ffect o f the seedling ag e of Acer pictum subsp. mono on the growth and crown competition in plantation. The tree height, diameter at breast height and crown area were significantly higher in the 3-year-old plantation than in the 1-year-old plantation. The H/D ratio decreased as the planting seedling age increased, and it was found that diameter growth was induced compared to height growth. It was interpreted that the total annual growth of trees by plantation sites showed a significant difference according to the planting seedling age, which influenced the diameter growth. The Crown Competition Index (CCF) and the Crown Competition Rate (CCR), which can evaluate the degree of crown competition in the plantation stand, also showed the same tendency such as tree height, diameter at breast height, and annual ring growth. In conclusion, planting of 3-year-old seedling is expected to b e advantag eous in terms of the g rowth of A. pictum subsp. mono, and the results of this study are expected to be used in management decisions such as the timing and amount of sap collection in plantation.
