摘要:
研究以广东省郁南林场大东坑工区内 51 年生灰木莲 Manglietia conifera 为研究对象，对灰木莲树高、胸径、材积、树干通直度、侧枝生长习性等指标进行调查和分析。结果表明：51 年生灰木莲生长良好，胸径平均为 44.28 cm，最大为 79.60 cm，树高平均为 20.79 m，最高为 27.00 m，单株材积平均为 1.48 m3，最高为 3.65 m3。可见，灰木莲引种在广东郁南适应性强，能够生长良好，具有生长速度快，树干通直，自然整枝好等特点，是该地区可以推广种植和培育大径材的优良树种。

Abstract:
In order to study the Manglietia conifera tree growth in Yunan of Guangdong, we investigated 51 years old M. conifera trees in Yunan Forest Farm, we studied and collected the data of tree height, DBH, volume, trunk straightness and growth habits of lateral branches. The results showed that 51 years old M. conifera trees grow well. The average DBH of M. conifera trees was 44.28 cm, and the maximums value was 79.60 cm. The average height of the tree was 20.79 m, and the maximum value was 27.00 m. The average volume was 1.48 m3,and the maximum volume was 3.65 m3 . M. conifera that were introduced to Yunan of Guangdong have strong adaptability and can grow well for a long term. It has the characteristics of fast growth, straight trunk and good natural pruning. It is an excellent potential tree species for planting and cultivating large-diameter timber in Yunan of Guangdong.
