| 摘 要： | 通过对木麻黄老林带分别采取不同采伐宽度种植木麻黄优良无性系以及建立多树种混交配置更新,结果表明:10m×10m、20m×20m及30m×30m采伐带宽度更新木麻黄无性系粤701生长显著差异,以30m×30m采伐宽度更新,林木生长最佳。木麻黄与厚荚相思、厚荚相思与湿地松单行混交,有不同程度上的种间矛盾,林分生长不太稳定,因此不宜采用行间混交。木麻黄与厚荚相思、刚果12号桉、湿地松以及厚荚相思与湿地松采用多行(带状)混交,其更新效果普遍较好,两者之间竞相生长,种间关系比较协调。多行混交不仅可以避免树种之间挤压,而且整个林分形成多层次空间结构,从而形成防护林树种的多样性和较好的景观。

| Abstract: | Adopting different felling breadth,superior Casuarina equisetioflia clones were planted on the old shelerbelt of Casuarina equisetioflia and mixing of multispecies .Results showed regeneration of Casuarina equisetioflia clones(Yue 701) with the felling breadth of 10m×10m,20m×20m,30m×30m had significant differences.Regeneration by the felling breadth of 30m×30m,the forest trees grew best. Mixture by single line of Casuarina equisetioflia and Acacia crassicarpa,Acacia crassicarpa and slash pine had contradictory of species in varying degree.It was not stable in growth of stand,so it was not suitable to adopt mixture by lines.Mixed by lines (strips) of Casuarina equisetioflia with Acacia crassicarpa,Eucalyptus 12 ABL,slash pine and Acacia crassicarpa with slash pine had the better regeneration effect.Relation of the two species was coordinate. Mixed by lines not only can avoid squeeze of species ,but also form the space structures of administrative levels , thus formed the diversity of protection forest species and better landscape. |
