不同种源海红豆生长比较分析及优良材料初步选择

Study on Growing Difference in Adenanthera pavonina L. of different Provenances in Fujian province and Fine Material Preliminary Selection

2009年在西陂林场开展了海红豆种源试验调查,结果表明:参试的3个种源造林1a生长表现差异显著,以缅甸种源生长表现最佳,平均树高达到125.6cm;其次是台湾种源,平均树高达到124.73cm。种源中各单株的生长表现差异明显,以树高生长为主要指标,在缅甸种源中初步选出9号、25号、13号、11号、5号等5个优良单株,树高生长达到1.55～1.80m,比总体平均值增加了23%～43%;在南宁种源中,初步选出24号、4号、23号、15号、13号、12号、8号等7个优良单株,树高生长达1.30～1.50m,比总体平均值增加了22%～41%;在台湾种源中,初步选出25号、21号、20号、19号、8号、22号、18号等7个优良单株,1生树高生长达1.60～1.75m,比各单株总体平均值增加了28%～40%。海红豆生长(树高、胸径、冠幅)一整年不间断,是速生丰产林的优良树种,5～10月份生长比较快,10月份以后生长相对缓慢。

The three provenances about Adenanthera pavonina L. of Myanmar,Nanning and Taiwan were studied in Xipi national forest farm of Fujian Hua＇an in 2009. The results are as follows. The year growth of the three provenances about Adenanthera pavonina L.showed significant difference,and the provenance of Myanmar were growing best,the average tree height of which was 125.6cm; The provenance of Taiwan was second,the average tree height of which was 124.73cm. In each provenance,the plant＇s growth differences were significant. With height growth as the main indicator,the trees of 9,25,13,11,5 were excellent plant trees about the provenance of Myanmar,and the tree height was 1.55~1.80m that was higher than the overall average by 23%~43%; About the provenance of Nanning,the trees of 24,4,23,15,13,12,8 were excellent plant trees,and the tree height was 1.30~1.50m that was higher than the overall average by 22%~41%; About the provenance of Taiwan,the trees of 25,21,20,19,8,22,18 were excellent plant trees,and the tree height was 1.60~1.75m that was higher than the overall average by 28%~40%. The tree height,diameter and average crown of Adenanthera pavonina L. were increasing throughout the year without interruption,which were growing fast from May to October and slowly after October,and Adenanthera pavonina L.is an excellent fast growing forest tree species.
