摘  要:
长期以来,油杉属树种,只开发利用而未人工造林,资源濒于枯竭。国内仅少数植物园引种作观察或观赏,国外也仅英、美、意等国零星引种于公园庭院,尚无系统的作为用材树种造林的研究。广西林业科学研究所从1957年开始油杉人工引种驯化试验,在完成广西油杉属物种资源调查和采种育苗试验基础上,对油杉属中的4个主要树种进行造林试验,至1989年止,已推广造林700ha,并总结了一整套人工造林的技术措施。一、试验内容自1978年以来,先后在全区设试验点8个,试验林80多公顷,进行了造林地选择、物种比较、密度、混交造林、抚育等试验,各试点的试验内容有所不同。1989年5月至9月对各点的试验林及推广林进行了全面的调查、总结。

摘  要:
Based on a series of plantation experiments with Keteteeria tree speciesfrom 1978 to 1989, which studied site selection, species comparision, density,mixed forest and tending, as well as artificial plantation growth, a set ofartificial reproduction techniques and measures for Keteleeria tree species hadbeen sumed up. Up to now, the trees have been planted more than 600ha inGuang Xi. The average height of 9-11-years-old trees is 7.66m, and theaverage diameter at breast height is 9, 91cm, growing stock volume 81.9m~3/ha.The benefits of artificial reproducting Keteleeria tree species are striking, therefore which provides a main kind of forestation tree species for south China.
