| 摘要: |
| 我场栽培花梨已近3年。实践表明，花梨在我场生长表现较好，2年生平均高2.48m，平均径1.78cm。立地不同生长差异大，山坡下生长好，高2.88m，径2.29cm；中部高2.61m，径1.77c m，上部生长差，高仅1.94m，径1.29cm。坡向对生长影响小，西坡径高生长量比东坡分别大9.6%和4.1%；树冠生长状态与径高生长相似，好地生长好，反之生长差。说明，虽然造林措施相同，但立地对幼林生长影响大，因此造林时要因地制宜，要培育大径材必须用好地栽培。 |

| Abstract: |
| The trees of Dalbergia odorifera T. Chen, of high economic value, were introduced and planted from Hainan to Zhenhai Forest Farm two years ago. They generally grow well in the initial two years with mean height 2.48 m and mean diameter at breast height 1.78 cm. The growth of the tree species were controlled by site condition. They grow well in the lower parts of hills, conversely on the top. The mean height and mean diameter at breast height were 2.88m and 2.29cm in the lower parts, 2.61m and 1.77cm in the middle, and 1.94 m and 1.29 cm in the top respectively. The direction of the hills less affects the growth of the tree species. The height and diameter in the west slope was increased by 9.6% and 4.1% compared with in the north direction. The canopy development of the tree species, like the growth in height and diameter, closely correspond to the site condition. Results indicated the growth of the young trees was affected by site conditions, so it is necessary to match batter site to the species, particular for cultivating its large diameter timber. |
