CK-OT, control fertilizer with optimal temperature (OT); CK-HT, control fertilizer with high-temperature stress (HTS); Mg-OT, Mg with OT; Mg-HT, and Mg with HTS. Means were compared using Duncan’s multiple-comparison tests. Different lowercase letters after data in the same column indicate significant variations within the same year at P < 0.05.
