这句话有语法错误吗：The result of the 6-year field trial show that the average yield is in the order Con treatment 85 Mg ha-1 ≥ Opt treatment 83 Mg ha-1 Min treatment 66 Mg ha-1 Fig 1

这句话有一个语法错误。应该是 "The result of the 6-year field trial shows that the average yield is in the order of Con treatment (8.5 Mg ha-1) ≥ Opt treatment (8.3 Mg ha-1) > Min treatment (6.6 Mg ha-1) (Fig. 1)."，其中 "show" 要用单数形式。
