摘要
在云南省云南沉香主要栽植区的6个不同试验点,对3a生云南沉香幼林树高、地径、保存率等进行了观测研究。结果表明:不同试验点云南沉香树高、地径生长量差异显著,保存率无差异;生长量呈现由低海拔向高海拔、由南向北、由砖红壤向红壤、赤红壤过渡递减趋势;在勐养镇试验点生长最好,在思茅整碗生长最差;在景洪及普洱地区应优先选择低海拔、热量高、砖红壤的地域栽植。
Tree height, diameter and preservation rate of three years old young forest of Aquilaria yunnanensis in six experimental plots were observed. The results showed: i) there was significant difference in tree height and diameter and no difference in preservation rate; ii) the growth was best in the experimental land of Mengyang ,and the Zhengwan of Simao was the worst; iii)the growth performed declining trend from south to north, from low altitude to high altitude and from laterite to red earth with lateritic red soil; iv) Aquilaria yunnanensis should be planted in Jinghong and Pu'er areas with low altitude, high heat and laterite soil.
