对4种林型林冠下和一种皆伐迹地进行去死活地被物、去死活地被物并去根系盘结层、盖塑料布、盖铁丝网等人工播种试验,通过比较得出发芽出苗情况为“去掉死活地被物出苗最高峰的日期,比去灌木处理早4d,比对照处理早15d.赤杨落叶松林型当采用去除植被枯落物并用盖塑料布处理时,有极好的出苗现象(出苗率达53.0%),其他林型的同类处理出苗也良好.试验证明,落叶松的更新除种源外,种床条件十分重要,死活地被层使落叶松种子芽成苗率甚低;动物危害也相当严重;有的试验在除去地被物以后出现了日灼危害,需进一步研究.
Four kinds of forest under canopy and a deforestation land to go live quilt, to live quilt and to the root panicle layer, covered with plastic sheeting, covered barbed wire and other artificial sowing experiments by comparing the germination of the emergence of the situation as ”The date of removal of the peak of life and death was earlier than the treatment of shrubs for 4 days, 15 days earlier than the control treatment." Red-leafed Larix forest species have excellent emergence when used to remove vegetation litter and cover with plastic sheeting Phenomenon (emergence rate of 53.0%), similar to other forest types of emergence is also good.Experiments show that, in addition to the regeneration of larches, the seedbed conditions are very important, so that the layers of live and die larch seedling seedling rate is very Low; animal hazards are quite serious; some trials in the removal of the floor after the occurrence of sunburn damage, further research is needed.
