柚木(Tectona grandis.L.f.)原产印度、缅甸、泰国和印度尼西亚,在老挝的东北部也有天然分布,是东南亚的主要造林树种。我国引种柚木已有较长的历史,广东、广西、云南、台湾均有引种,云南有百年的大树。我省的福州、厦门、漳州等地也有引种,1961年我场也曾引种过柚木。要发展速生丰产的柚木林,目前主要存在现有种源对造林地要求过高,限制了柚木发展的问题。为此,进行种源试验,以寻找适生的(尤其是耐土壤脊薄、粘实、PH 值低)的柚木
Teak (Tectona grandis.L.f.) Native India, Myanmar, Thailand and Indonesia, also has a natural distribution in the northeast of Laos, is the main afforestation species in Southeast Asia. The introduction of teak in our country has a long history, with introduction in Guangdong, Guangxi, Yunnan and Taiwan, and a hundred-year-old tree in Yunnan. Fuzhou, Xiamen, Zhangzhou and other places also introduced in our province. In 1961, we also introduced teak. To develop fast-growing and high-yielding teak forests, there are mainly existing provenances that require too much for afforestation and restrict the development of teak. For this purpose, provenance tests were conducted to find suitable teak plants (especially those with low soil resistance, low pH value)
