刺槐(Robinia pseudoacaeia)是我省太山区主要造林树种之一,现有大面积成林,这对改善生态环境、保持水土、涵养水源、解决民用材及烧材等起到了一定作用。但是,近几年由于严重地季节性干旱,致使山地刺槐人工林大面积出现过早地衰退,枯梢严重,树干回缩,树皮发黑,木材内腐,林相残破。因此研究探讨这种残、疏刺槐林适宜的更新技术,以继续发挥其多种生态与经济效益就成了亟待解决的问题。于是我们在
Robinia pseudoacaeia is one of the main afforestation species in the mountainous area of our province. It has large-scale afforestation. It plays a certain role in improving the ecological environment, maintaining water and soil, conserving water sources, solving civil timber and burning wood. However, due to the severe seasonal drought in recent years, the large area of mountain acacia plantation has been decayed prematurely, with serious shoots, retracted trunk, black bark, decayed wood and broken forest. Therefore, it is an urgent issue to study and explore the suitable updating technology of this residue and sparse Huai Lin in order to continue to exert its various ecological and economic benefits. So we are here
