摘要
为了确定黑木相思Acacia melanoxylon在肇庆市等粤西地区的适宜种植海拔,文章以黑木相思无性系SR17为研究材料,在广东省西江林场开展110~410 m海拔种植对比试验。在黑木相思0.5年生和1年生时测定了树高、地径、冠幅等生长指标,结果表明海拔350~360和400~410 m两个处理的树高、地径和冠幅生长达到最大,说明黑木相思在肇庆地区最适宜的种植海拔为350~410 m。
In order to determine the suitable planting altitude of Acacia melanoxylon in Zhaoqing and other western Guangdong areas, the study took A. melanoxylon clone SR17 as the research material and carried out a comparative planting experiment at different altitudes in Xijiang Forest Farm of Guangdong province. The growth and quality indexes of tree height, ground diameter and crown width were measured twice at 0.5 and 1 year old.The results showed that the growth of tree height, ground diameter and crown width reached the maximum at 350-360 m and 400-410 m above sea level, indicating that the most suitable planting altitude of A.melanoxylon in Zhaoqing was 350-410 m. West Guangdong is the main cultivation area of A. melanoxylon, and A.melanoxylon requires relatively strict altitude and temperature. Therefore, the determination of its suitable planting altitude has important guiding significance for the efficient cultivation and promotion of A. melanoxylon.
