Method for promoting renewal of artificial forest

The invention discloses a method for promoting renewal of an artificial forest. The method comprises the following steps: removing litters on a renewal promoting forest land, and exposing a part of the ground of the forest land; sowing forest tree seeds on the exposed ground. According to the method, the natural renewal grade, the renewal density and the sowing germination rate of the artificial forest can be remarkably improved, tests prove that the renewal density of the method can reach up to 8633.33 strains * hm , the seed germination rate can reach 1.79%, and all of these are achieved under ditch-shaped treatment. Compared with existing artificial afforestation, the best litter removing mode, namely ditch-shaped treatment, promotes renewal of the forest, and has the advantages that the workload and renewal cost are greatly reduced. 本发明公开一种促进人工林更新的方法，包括如下步骤：对促更林地上的枯落物进行清理，裸露出部分林地地面；在裸露地面上播撒林间林木种子。本发明能够显著提升人工林的天然更新等级、更新密度和播种发芽率，试验证明，本发明方法更新密度最高可达到8633.33株·hm-2，种子发芽率可达到1.79％，均是在沟状处理下实现的。最佳枯落物清理方式--沟状处理
