秋季养分回收是草地多年生植物保存和高效利用养分的关键机制。放牧对植物养分回收的影响可能改变根系养分储存,进一步影响植物在翌年春季的返青生长。多数研究关注于放牧草地植物养分回收和保存,而其对植物在翌年春季返青生长的影响研究则较少。本研究以半干旱草原多年生优势禾草——大针茅(Stipa grandis)为模式植物,具体评估了4种季节性放牧管理下(不放牧、春季放牧、夏季放牧和秋季放牧)大针茅植株水平的养分回收特征(养分回收度、回收效率和回收通量)、根系养分动态,以及翌年植物返青状况,旨在探究植物养分回收、根系养分储存和翌年返青生长对不同季节放牧的响应。研究结果显示,(i)大针茅氮回收效率为51%–66%、磷回收效率为58%–80%,养分回收通量在秋季放牧下最低,在春季放牧下最高。(ii)大针茅根系养分储存特征在夏季放牧下显著降低,在春季放牧下轻微下降,而在秋季放牧下则无变化。(iii)翌年春季大针茅返青生长状况在早春放牧下最佳,在秋季放牧下最差,这一现象主要受土壤水分的影响,而与根系养分储存无关。本研究为深入了解植物养分循环过程,建立草原保护和合理放牧管理制度提供了理论依据。
