Benefit：
Soil application: Before sowing, spread 20-50 kg of zinc sulfate per hectare. At sowing, strip application of 5-10 kg ZnO per hectare to promote crop root uptake. Zinc fertilizer seed/root treatment: 2.2-4.4 kg ZnO/ton seed coating, or 2-4% ZnSO4 solution on seedling roots or potato seed pieces to meet early crop needs for zinc. Foliar spraying: 3 and 5 weeks after seedling emergence, spray 100 liters per hectare of ZnSO4.7H 2O solution (1 kg ZnSO₄·7H₂O + 1 kg (ammonium nitrate + urea) + 100 ml surface sorbent/100 liters or 1-2% ZnO suspension) Concentrated application of zinc enrichment in seedbeds: Before sowing, spread 20-30 kg of zinc (ZnS or ZnO) per hectare. New methods of zinc fertilizer production: Add zinc fertilizer or coated zinc fertilizer to the compound fertilizer granulation process; acidic compound fertilizer to promote zinc fertilizer effectiveness and crop uptake irrigation fertilization: Mix zinc fertilizer and acidic NPK fertilizer into irrigation water to promote uniform distribution and homogeneous mixing of zinc fertilizer and improve zinc effectiveness and crop uptake in dry soil.
