【摘要】 通过对 7年生巨尾桉不同造林密度生长量、生物量分析 ,结合目标培育径阶所确定的理论适宜株数的研究 ,结果表明 ,在闽南山地Ⅲ级立地条件下 ,营造桉树短周期工业原料林适宜造林密度为 1 2 5 0～ 1 798株·hm-2 ,采用该密度造林不但可以培育市场畅销的规格材且生长量较高 ,可取得较好的经济效益更多还原

【Abstract】 The results reveal that under the conditions of the third-class sites in the Southern Fujian mountain areas,the suitable planting density is 1250～1798 trees/hm 2 for building eucalyptus short-cycle industrial raw material forests; and adopting the present density to conduct afforestation may culture the best-selling dimension lumber with higher growth and may obtain better economic benefits.更多还原
