Carbon deposition in soil rhizosphere following amendments with compost and its soluble fractions, as evaluated by combined soil-plant rhizobox and reporter gene systems.

本研究测定了玉米（Zea mays L.）根系在施用堆肥及其可溶组分土壤中释放的有机碳。根箱系统中，上层土壤与根系通过尼龙膜与下层根际土壤分隔；处理仅施加于上层，下层用发光生物传感器测定根系释放的生物可利用有机碳（根际沉积）。根箱–植物系统分别施用堆肥（COM）、堆肥水提物（TEA）以及从堆肥溶解有机质（DOM）中分离的疏水组分（H...
