摘要
于 1995年在乐昌林场引种米老排并进行生长调查和分析 ,试验结果表明 :米老排适宜在阳光充足的阳坡和较肥沃的立地上生长。 7.5年生米老排人工林平均树高达 11.15m ,平均胸径 11.71cm ,最大胸径达 18.80cm ,平均单株材积 0 .0 5 0 4m3,平均蓄积量 82 .4 1m3/hm2 ,年生长量达 10 .99m3/hm2 ,生长量与原产地相近。林地腐殖质层增厚、变松。米老排引种取得良好效果 ,适宜在广东北部林区大面积推广种植。
Mytilaria laosensis was introduced to Lecheng Forest Farm in 1995, and the investigation of young plantations was conducted at 6.5 and 7.5 years old.
