Changes in ARG absolute gene copies in four treatments. A, B, C and D represent the four different treatments. Treatment A only contained basal soil; treatment B had wuyiencin sprayed on the basal soil during planting; and both treatment C and treatment D were supplemented with chemical fertilizers containing NaH4Cl at 150 mg/kg DW (dry weight), Ca (H2PO4)2 at 150 mg/kg DW, and KCl at 100 mg/kg DW, with treatment C sprayed without wuyiencin during planting and treatment D sprayed with wuyiencin.
