摘　　要：草木灰是传统多效物料,能防治农林病虫害、克服连作障碍,但其作用原理远非明了。以文献调研为主,辅以甘肃天水草木灰民间使用经验,总结分析草木灰传统知识,指出草木灰主要结构成分为生物炭,其防治农林病虫害、克服连作障碍的原理在于其强大的吸附性能,还可能与其碳纳米颗粒和孔隙纳米结构有关。作为草木灰的换代物料,生物炭将在实现双碳目标中大有作为。Plant ash is a traditional multi-effect material,which can control agricultural and forestry pests and overcome the obstacles of continuous cropping,but its mechanism is far from clear.Based on the literature research and supplemented by the folk use experience of plant ash in Tianshui,Gansu province,the traditional knowledge of plant ash was summarized and analyzed.It was pointed out that the main structural component of plant ash was biochar,and the principle of its prevention and control of agricultural and forestry diseases and insect pests and overcoming the obstacles of continuous cultivation lies in its strong adsorption performance,which may also be related to its carbon nanoparticles and pore nanostructures.As a replacement material for plant ash,biochar will play a great role in achieving the goal of double carbon.
