木麻黄优良无性系引进与更新造林效果初步分析

为了丰富和增加海岸带防护林体系建设的新材料,引进木麻黄新无性系进行育苗与更新造林试验,结果表明:9个参试的木麻黄无性系造林成活率均达到95.9%以上;现有保存率也均达到95.5%以上,说明新引进的木麻黄无性系都比较适宜新的生态环境。试验还表明,木麻黄无性系之间最主要的胸径、树高生长量处于快速成长水平,真正的竞争才开始,有待进一步观察研究。

Effect of Introduction and Reforestation for Superior Clones of Casuarina equisetifolia

In order to enrich and increase new materials of coastal shelter forests system and introduce Casuarina equisetifolia clones,experiments of seedling-raising and regeneration were conducted.The results show that survival ratio of 9 clones of Casuarina equisetifolia tested in the trails all reach above 95.9%.Existing preservation ratio also reach above 95.5%.It illustrate that Casuarina equisetifolia clones newly introduced are suitable for new eco-environment.Experiments show that growth of main DBH and tree height among Casuarina equisetifolia clones is in fast-growing level.Real competition is just beginning.Further research and observation are expected.
