摘要
在华安县西陂国有林场分别对从马来西亚、越南、厦门、福州四种不同的海红豆种源进行海红豆在福建地区的引种驯化实验,结果表明:马来西亚种源海红豆幼树的树高最高,平均树高为151.5 cm,其最大树高达到220 cm.厦门种源海红豆幼树的平均树高比马来西亚种源海红豆的低出46 cm,厦门种源海红豆的最大树高也仅有165 cm,平均地径年生长量最低,平均冠幅也最小,幼树的长势相对最差.以树高为优良单株的选择指标,越南种源海红豆的优选率为20%,福州、马来西亚和厦门的优选率相同,为28%.由此可见,马来西亚种源海红豆幼树生长初期的生长表现明显优于厦门种源的,比较适合在福建地区栽培.福州、越南种源海红豆在福建地区也有一定的引种栽培价值.
Choose four different Adenanthera pavonina from Malaysia, Vietnam, xiamen and fuzhou,planting on Xipo state-owned forest farm of Huaan County for the Adenanthera pavonina domesticated experiment in fujian re- gion,and the results showed that： （2）In the four provenance which are selected,Malaysia among the Adenanthera pavonina of sapling tree height is highest, the average tree height of 151.5 cm, the trees up to 220 cm high. Adenanthera pavonina average tree height of Xiamen provenance is low 46cm than Malaysia,the highest tree only 165 cm,and Xiamen Adenanthera pavonina＇s average annual growth in diameter, average crown breadth and apling growth are all the worst.Taking the tree height as a selection criteria of superior individual,the preferred rate of Vietnam provenance Adenanthera pavonina is 20%, and xiamen, fuzhou, Malaysia preferred rate is the same, at 28%.Obviously,Malaysia provenance Adenanthera pavonina in the early growth performance was obviously better than that of xiamen provenances, which is suitable for cultivation in fujian area.Fuzhou and Vietnam provenance Adenanthera pavonina also has a good value of introduction and cultivation in fujian area.
