摘要
对巨尾桉、尾叶桉 3种株行距配置造林试验研究表明 ,在同为 16 6 5株·hm-2 造林密度的情况下 ,不同株行距配置对林分生长、抗逆性、林内光照强度、林下凋落物及林地土壤肥力的影响有所差异。闽南山地造林采用 2m× 3m或 1 5m× 4m的配置并按“品”字型排列植穴所形成的营养空间较为合理 ,有利于林分生长和地力维持 ;而 1m× 6m的配置 ,表现出风折木多、林下植被旺盛、枯枝落叶量少、土壤养分含量少及林分生产力低等特点。
The experimental studies on Eucalyptus grandis × E.urophylla and E.urophylla afforestation with three types of plant and row spacing arrangement reveal that under the same situation of afforestation density of 1665 trees per hm,the effects of the different plant and row spacing arrangement on the stand,growth,resistance,intensity of illumination inside the stands,deciduous things under the stands and forest soil fertility are somewhat different.Adopting the afforestation arrangement of 2m×3m or 1.5m×4m in mountain areas of South Fujian is advantageous to the stand growth and soil fertility maintenance whereas the arrangement of 1m×6m causes the following defects:many wind-breakage trees,vigorous vegetation under the stands,few dry branches and fallen leaves,few soil nutrients and low stand productivity.
