摘　　要：以15 a生的适生区橡胶林下定植了1.5 a以后的5个热带珍贵用材树种铁力木、格木、羯布罗香、望天树、海南黄花梨作为观测对象,对5个树种分别在2016年2月、4月、6月、8月、12月和2017年2月进行地径和树高观测其生长量。结果发现5个树种地径生长量高峰期基本为为每年的6月~8月;树高生长量高峰期基本为每年10月~12月,其中海南黄花梨的树高生长高峰期在2月—4月,羯布罗香的树高生长高峰期在12月~2月期间。A total of five tropical and precious timber species aged 1.5 were planted under the rubber plantation aged 15 and the ground diameter and height of the five species were observed in February, Apill, June, August, December 2016, and February 2017. The results showed that the peak growth period of ground diameter was basically between June and August each year. The peak growth period of tree height was basically between October and December each year, and the peak growth period of tree height of Dalbergia odorifera was between February and April, Dipterocarpus turbinatusGaertn tree height growth peak occurred during December and February period.
