摘要
以8 a橡胶林下定植1 a以后的铁力木和格木作为观测对象,对两个树种分别在3月、6月、9月、12月进行4次树高观测.结果发现两个树种树高的生长高峰期都是在6月～9月,此期间树高生长量最大,铁力木平均树高生长量为14.97 cm,格木平均树高生长量为34.65m,铁力木和格木生长表现最好的栽培模式为铁力木＋格木＋望天树.
Taking annual Mesuaferrea and Erythrophleumfordii trees planted under 8 years old rubber for- est as the observation object, four times of investigation were made on the tree height of two tree species in March, June, September and December. The results showed that the peak height growth of the two species appeared from June to September,and as for the largest amount of height growth,the average tree height growth of Mesua ferrea was 14. 97 cm, and the average tree height growth of Erythrophleum fordii was 34. 65 cm. In addition, the best cultivation model was found to be Mesua ferrea ＋ Erythrophleum fordii ＋ parashorea cathayensis.
