湛江木麻黄无性系选择试验

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。

Selection Experiments of Casuarina equisetifolia Clones

The selection experiments with 26 clones of Casuarina equisetifolia were established on two different types of sites in Zhanjiang of Guangdong. The authors investigated and analysed for height,DBH, canopy,survival rate and resistance of clones.The results showed that clone Dongli 6, Nanshan Hybrid 2 and Nanshan 2 were better than clone A8 which commonly use.The three clones were suitable to plant in sandy laterite woodland with rich organic matter. The clone 105, Dongli 12, Dongli 6, Ping 2, Nanshan Hybid 5 and Dongli 10 were also better than clone A8, the six clones were suitable to plant in coastal sandy woodland. The clones Dongli 6 were the best one in growth performance, adaptation and resistance on two different sites.
