近年来,由于生态环境破坏的日益严重,以及人们对古树的保护不力,再加上古树的“年事已高”,所以出现了不同程度的毁坏,甚至死亡。为了使这些“历史老人”能恢复昔日容颜,本文提出古树的生物学复壮技术,对天水的古树进行彻底整修复壮,再现往日绿荫。 一、生物学复壮技术方法 In recent years, due to the increasingly serious damage to the ecological environment and the poor protection of ancient trees, as well as the “old age” of ancient trees, there have been various degrees of destruction and even death. In order to enable these “historical elders” to restore their former looks, this paper presents the biological rejuvenation techniques of the ancient trees, thoroughly reconstructing and rejuvenating the ancient trees of Tianshui and reappearing past greenery. First, the biological rejuvenation techniques
