When purchasing irrigation equipment, how to select center pivot vs drip irrigation by agronomy?
• For contiguous corn/wheat ≥20 ha, prefer center pivot; coverage radius up to 400 m.
• For orchards, greenhouse vegetables, and high water-saving plots, choose drip with uniformity ≥90%.
• Center pivot requires sprinkler flow CV ≤5% and end pressure ≥0.15 MPa.
• Drip needs filtration; with high sand, use sand + disc two-stage filters.
• Match local evaporation and peak crop water demand to size system design flow.
