摘要
1991年在东川市进行银合欢Leucaenaleucocephala薪炭林的营造技术及经营措施的研究。银合欢林分经过32个月的生长,于1994年4月10日,对试验进行了全面的调查,通过对调查数据统计分析后得出结果:1.银合欢在东川市河谷地区生长良好。采用营养袋苗造林,60cm×60cm的撩壕整地,2m×1m的造林密度,成活率可达96%以上。2.将银合欢作为薪炭林来经营,具有生长快,产柴量高,燃烧值高等特点。试验还证明,短期轮伐,保留伐桩10cm,用锯子平锯处理的,保留伐桩100cm,用刀斜砍处理的,效果最好。建议适宜营造银合欢的地区将银合欢林作为薪炭林来经营,可提高单位面积产量。采用短期采伐,对保留的伐桩加施追肥效果更好。
A study on the silvicultural techniques and management measuresof Leucaena leucocephala fuelwood plantations has been made since 1 99 1.The standof Leucaena leucocephala was investigated in an all-round way on April 10,1 994 whenthe stand was 32 months old The data collected from this investigation have been studiedwith statistical analyses,and the resuIts show as follows:1.Established in the river valleyareas of Dongchuan,the Leucaena leucocephala plantations grow very well with a surviv-al rate over 96 % after being planted by means of pot cuItivation of seedlings and landpreparation with fosses of 60 cm by 60 cm,and with a density of 2 m by 1 m. 2.As oneof the species for fuelwood plantations,Leucaena leucocephala is characterized os a fastgrowing species which produces high yield fuelwood with high calorific value. Inaddition,the best effects have also come out of the experiment on short-term rotationswith 1 0-cm-high stumps treated with saws and 1 00-cm-high stumps treated with chop-pers.
