摘要
为实现林地的快速恢复和重建,满足生态环境的需求,矮林作业是森林经营的重要方式。在林木矮林作业中,萌芽更新是首要的一步,它对植株后期生物量积累和经济产量的影响至关重要。伐桩方式、采伐季节和强度、激素和养分4个因素是影响林木矮林萌芽更新的主要因素,需根据树种的不同生物学特性选择合适的萌芽更新技术来保障林地的质量。该研究对森林的恢复和重建、林木的培育和人工林的开发利用提供了重要的指导。
In order to realize the rapid restoration and reconstruction of forest land and meet the needs of ecological environment,coppice forest operation is an important way of forest management.Budding regeneration is the first step in the operation of dwarf forest,which is very important to the accumulation of biomass and economic yield in the later stage of plant.Four factors of cutting pile mode,cutting season and intensity,hormone and nutrient are the main factors affecting the germination renewal of coppice forest.It is necessary to select the appropriate germination regeneration technology according to the different biological characteristics of tree species to ensure the quality of forest land.This study provides important guidance for forest restoration and reconstruction,forest cultivation and plantation development and utilization.
