在广东省湛江市2个不同类型的立地上进行木麻黄无性系选择试验,调查分析树高、胸径、冠幅、保存率和抗逆性。结果表明:湛江市林业科学研究所的东里6、南山杂2和南山2无性系优于对照,适于在有机质丰富的沙质砖红壤立地造林。东海林场的105、东里12、东里6、平2、南山杂5和东里10无性系优于对照,适于在沿海滨海沙土立地造林。在不同造林地表现均优的只有东里6,其生长表现最好,适应范围最广,抗逆性较强。
The clonal selection test of Casuarina equisetifolia was carried out on two different types of stands in Zhanjiang, Guangdong Province. The tree height, DBH, crown width, preservation rate and stress resistance were investigated. The results showed that the clones of Dongli 6, Nanshanza 2 and Nanshan 2 in Zhanjiang Institute of Forestry were better than the control, which was suitable for site afforestation in the sandy soil with abundant organic matter. Donghai Forest Farm 105, Dongli 12, Dongli 6, Ping 2, Nanshanza 5 and Dongli 10 clones were better than the control, suitable for coastal planting in coastal littorality. Only the Dongli 6, which has the best performance in different afforestation areas, has the best growth performance, widest adaptability and strong resistance.
