衰败毛竹林恢复期经营技术措施研究

Studying on management techniques for degenerated forest of Phyllostachys edulis during recovering stage

对衰败毛竹林恢复期经营技术措施进行探讨,分析了强化留笋养竹、不同抚育方式、不同施肥方式对衰败毛竹低产林的改造效果。试验结果表明:衰败毛竹低产林恢复期强化留笋养竹、化学除草是良好的抚育方法,施肥方式应以伐桩施肥为主,调整竹林结构是衰败毛竹林恢复产量的可靠保证。

In this article, the management technologies in recovering stage of degenerated forest of Phyllostachys edulis were probed, the recovering efficiencies of degenerated bamboo forest by bamboo shoot reservation, different cultivating ways and fertilization methods were analyzed. The results showed that for the recovery of Phyllostachys edulis, it needs to preserve the bamboo shoots for promoting the growth of bamboo plants, remove weeds by chemical reagents, and the main fertilization manner was applying fertilizer to bamboo residual holes when the stumps were removed. The construction of degenerated Phyllostachys edulis forest should be adjusted in order to regain the stable yield of Phyllostachys edulis.
