为探索一种具有降镉效应的南荻炭基土壤调理剂以缓解湖南省稻田镉污染现状,并为洞庭湖区南荻资源的利用提供新途径。试验以深两优5814为材料,将南荻炭与五种镉钝化剂按L25(5~6)正交表进行复配,通过模拟镉污染土壤盆栽试验,研究各复配因素施用对水稻镉含量的影响,进而确定南荻炭基降镉土壤调理剂的最佳配伍。结果表明:南荻炭与五种镉钝化剂互作可显著降低(P

This study was designed to explore the interaction effects of Miscanthus lutarioriparius-derived biochar with five cadmium(Cd) passivators on rice Cd content and yield. Based on the results, it was expected to determine their optimum application rates and develop a M. lutarioriparius biochar-based soil conditioner. The L25(5~6)orthogonal test was firstly used to determine the experimental treatments and then 25 treatments with three replications were conducted in a pot trial. Results showed that the interaction of the six tested factors could b...
