蒙古栎天然林大径材定向培育技术模式

对蒙古栎（幼龄林和中龄林分别开展了水肥耦合、密度+施肥、密度+修枝和密度+施肥+修枝等技术集成实验，建立蒙古栎大径材定向培育集成技术。确定进入中龄林阶段，采用林分密度调控和施肥集成技术，通过合理的密度调控和施肥（1300株·ha-1+200 g N·株-1·a-1）措施，林木胸径年生长量显著提高。

Integrated technology experiments including water-fertilizer coupling, density + fertilization, density + pruning, and density + fertilization + pruning were separately conducted for young and middle-aged stands of Quercus mongolica, to develop integrated technologies for targeted cultivation of large-diameter Quercus mongolica timber. It was confirmed that for stands at the middle-aged stage, adopting integrated stand density regulation and fertilization measures, specifically rational density regulation combined with fertilization at 1300 trees·ha⁻¹ + 200 g N·tree⁻¹·a⁻¹, can significantly increase the annual diameter at breast height (DBH) growth of the trees.
