油杉系松科油杉属(Keteleeria Carr)树种。在广西境内天然分布广泛,是抗逆性强、生长较快和用途较广的优良用材树种之一。据调查,广西有7个油杉物种。目前,生产上较普遍引种栽培的有:矩鳞油杉(K. oblongaCheng et. L. K. Fu)、江南油杉(K. cyclolepisFlous)、油杉(K. fortunei(Mrr. )Carr. )和云南油杉(K. evelyniana Mast. )等四个种。自1979年以来,我们在油杉物种造林对比试验方面做了一些工作,并取得了显著的效果,现将试验的初步结果整理如下,供参考。一、基本情况
Oleaceae is a species of Keteleeria Carr. Widely distributed in Guangxi natural distribution, is strong resistance, rapid growth and wide use of one of the fine timber. According to the survey, there are 7 species of oleander in Guangxi. At present, the production is more commonly introduced and cultivated are: K. oblongaCheng et. LK Fu, konjac (K. cyclolepisFlous), K. fortunei (Mr fort.) Carr.) And Yunnan oil Fir (K. evelyniana Mast.) And other four species. Since 1979, we have done some work on afforestation comparative experiments of Olea europaeus and have achieved remarkable results. The preliminary results of the experiments are summarized below for reference. First, the basic situation
