| 摘要: |
| 2004年4月~2008年3月在广西崇左市龙峡山西面中坡进行银合欢(Leucaena leucocephala(Lam.) de Wit)直播造林试验。造林面积3.33hm2,试验分不清林不整地和铲除植被并松土两种整地方法进行造林,造林4年后调查造林的成林情况、生长情况和银合欢的天然林下更新情况。调查结果表明,造林前未经清林整地的地段造林失败,而造林前铲除植被并松土地段造林取得成功,林分郁闭度达0.7,林分平均高6.0m、平均胸径4.1cm,并具有良好的天然林下更新能力,能自然形成复层异龄林。 |

| Abstract: |
| From April 2004 to March 2008,silviculture experiments of Leucaena leucocephala (Lam.) de Wit are carried out on western middle slope hills of longxiashan in Chongzuo,Guangxi by direct sowing. The total afforestation area is 3.33hm2,including non preparation sites and preparation sites with vegetation cover dearcutting and soil ploughing. Situations of stands formation, trees growth and natural regenarations of Leucaena leucocephala (Lam.) de wit in the understory are surveyed four years after the experiments. The results of inventories show that the afforestations fail in areas without site preparations. However, stands successfally develop where vegetation cover was dearcut and soil was shallowly ploughed before sowing, with 0.7 in crown closure,an average 6.0m in height,4.1cm in breast-height diameter, good natural regenarations by seed shedding and uneven-aged woodlands with multiple stories are naturally establish. |
