Arbuscular mycorrhizal hyphal networks function as proton-conducting biowires, dissipating localized acidification from nitrification faster than diffusion-limited soil buffering allows.丛枝菌根菌丝网络充当质子导电生物导线，其消散硝化所致局部酸化的能力快于土壤缓冲能力所允许的扩散速率。

It further implies that fungicide use may degrade pH resilience more severely than previously quantified—particularly during sidedress nitrogen applications.这也意味着杀菌剂使用对pH韧性的破坏程度可能远超此前量化结果——尤其在追施氮肥期间。
-
Model simulations demonstrate that hyphal conductivity thresholds exist below which nitrification acidification overwhelms biological buffering capacity.模型模拟表明，存在菌丝导电性阈值；低于该阈值时，硝化酸化将压倒生物缓冲能力。
