摘要
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。
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.
