江西地处中亚热带 ,有丰富的树种资源 ,但真正用于人工造林的阔叶树种很少。通过对在吉安双江林场及德兴潭埠林业站的 9个优良阔叶树种的栽培试验结果分析 ,提出在江西重点推荐造林的阔叶树种为 :南酸枣、鹅掌楸、山杜英及蓝果树。还讨论了造林密度对阔叶树幼林生长的影响 ,认为造林密度 2m× 2m有利于林分的前期生长 ,但从造林成本及抚育等方面来考虑 ,以 2 .5m× 3m及 3m× 3m为宜
Jiangxi is located in the subtropical zone, rich in tree resources, but the real hardwood for afforestation rarely. Based on the analysis of the cultivation results of nine excellent broad-leaved tree species in Shuangjiang Forest Farm in Ji’An and Dexingtan Bu’er Forestry Station, it is proposed that the broad-leaved tree species recommended for afforestation in Jiangxi Province are as follows: Zizyphus jujuba, Liriodendron chinense, Du Fuying and blue fruit tree. The effect of planting density on the growth of young broadleaved young trees was also discussed. The planting density of 2m × 2m was beneficial to the early growth of the stand. Considering the afforestation cost and raising, the suitable planting density was 2.5m × 3m and 3m × 3m
