不同灌溉方式对北方玉米产量及品质影响研究

Key Points

• The study aims to analyze the effects of different irrigation methods on maize yield and quality in northern regions.
• Comparison of traditional irrigation (flood and furrow) and water-saving irrigation (spray, drip, and subsurface drip) methods.
• Assessment of maize growth metrics including ear number per mu, grain number per ear, thousand-grain weight, and total yield per mu.
• Examination of physiological metabolism, root growth, and soil environment under varying irrigation methods.
• Water-saving irrigation, particularly subsurface drip irrigation, significantly improves maize yield and quality.
• Enhanced water resource utilization efficiency observed with water-saving methods.
• Physiological and environmental adjustments linked to irrigation methods impact maize growth outcomes.
