环江县华山林场多树种造林试验

通过对环江县华山林场的桉树（Eucalyptus）、马尾松（Pinus massoniana）、湿地松（P.elliottii）、枫香（Liquidambar formosana）、香椿（Toona sinensis）、荷木（Schimaspp.）、五角枫（Acermono maxim）、白克木（Symingtonia populnea）、红花木莲（Rhodoleia championii）等9个树种进行造林对比试验研究,结果表明：桉树生长最快,适合进行短期轮伐经营;马尾松和湿地松表现良好,6年还处在生长旺盛期;枫香、香椿、荷木生长状况一般;五角枫的生长速度较慢,不宜作为速生用材树种,可作为观赏树种进行种植;白克木和红花木莲对环江县环境适应性较差,成活率及保存率均较低。

Experiment of Multi-species Afforestation in Huashan Forest Farm of Huanjiang County

The comparative experiment of multi-species afforestation which included Eucalyptus,Pinus massoniana,P.elliottii,Liquidambar formosana,Toona sinensis,Schima spp.,Acermono maxim,Symingtonia populnea,Rhodoleia championii was conducted in huashan forest farm of huanjiang county.The results showed that the tree species of the highest growth rate was Eucalyptus which was suitable for short rotation and Pinus massoniana and P.elliottii behaved well which could maintain high growth for six years.The state of Liquidambar formosana,Toona sinensis and Schima spp.was common,and the growth rate of Acermono maxim was low which was not suitable for fast-growing species and could be cultivated as ornamental species.The environmental adaptability of Symingtonia populnea and Rhodoleia championii was poor,of which the survival rate and retentional rate were low.
