摘　　要：引自泰国的小瘤龙脑香经１３年的栽培观测表明，该树种在引种地生长迅速，超过原产地部分地区；开花结果正常，用种子已繁育出一批新植株；对其落叶量和林下土壤养分的测定表明，该树种具有保持水土、改良土壤的作用。本文还就小瘤龙脑香的利用价值、造林的环境条件要求以及国外种植情况及其经济效益等方面，分析了该树种在我国热带地区大面积发展的可行性。Diptercarpits tuberculatus was introd uced from Thailand into Xishuang-banna，Yunnan Province in 1980.Thirteen-year cultivation showed that the plants grewfastar than in some areas of their native habitat．The flowering and fruiting of the plantswere normal．A group of seedlings were grown by seeds. The determination of fallenleaf amount and undersoil nutrient showed that the plant might serve as a species forconservation of soil and water as well as amelioration of soil.The feasibility of largescale development of D. tuberculatus in tropical area of China is also evaluated in regardto the utilization value of the species, environmental requirements of afforestation andthe conditions of its external cultivation and economic benefit as well.
