在海南省琼海县进行了不同林龄、不同采伐方式对大叶相思萌芽更新影响的研究，同时比较了保留不同萌条数量的萌芽林生长表现，结果表明：（１）林龄对伐桩萌芽率没有显著影响，但对伐桩存活率及萌条的径、高生长影响显著或极显著。林龄越大，萌芽更新效果越差；（２）皆伐和隔行采伐对大叶相思伐桩的萌芽率、萌条数量和存活率均无显著影响，但对萌条的径、高生长影响极显著。试验证明对大叶相思林分施以隔行采伐通过萌芽更新建立复层林分是可行的；（３）保留不同数量萌条对萌芽林早期（１．５年生）的径、高生长有极显著影响，但对后期（４．５年生）的生长影响不显著。每棵植株伐桩保留４根萌条的萌芽林生物产量最高，更新效果最好。
In Qionghai County of Hainan Province, the effects of different ages and different harvesting methods on the regeneration of sprouts of Acacia macrostachya were studied, and the growth performance of sprouting forests with different numbers of sprouts was compared. The results showed that: (1) There was no significant effect on the germination rate, but significant or very significant effect on the survival rate of stumps and diameter and height growth of sprout. (2) Clear-cut and interlaced cutting had no significant effect on the sprouting rate, the number of sprouting and the survival rate of Acacia crassicarpa. However, the effect of spruce on diameter and height growth significant. Experiments show that it is feasible to establish interlacing cutting through intercropping with alternate cutting of Acacia crassicarpa. (3) The retention of different numbers of adventitious buds has a very significant effect on the diameter and height growth of early stage (1.5 years) germinating forest , But had no significant effect on the growth of later stage (4.5 years old). The sprouting forest with 4 sprouts retained per plant stump had the highest biological yield and the best regeneration effect.
