摘要
为改变沿海地区造林树种单一状况,确保防护林生态系统稳定性,1992年在福建东山县赤山林场开展木麻黄大叶相思混交林和木麻黄纯林对比试验,研究结果表明,混交林中木麻黄保存率、树高、胸径生长量均大大超过木麻黄纯林;混交林防护效益明显大于木麻黄纯林;混交林林地土壤肥力高,改土效果显著。
In order to change the single situation of plantation species in the costal area and ensure the stability of ecological system of protective forest,the experiment of mixed forest of Casuarina and Acacia auriculaeformis compared with the pure forest of Casuarina was carried out in 1992.The results showed that the preserved rate, the growth increment of height and diameter of mixed forest were superior to the pure of Casuarina;the protective benefits of mixed forest were obviously larger than that of the pure of Casuarina;the soil fertility in the mixed forest was apparently improved.
