Abstract

Abstract:

【Objective】 This study aimed to clarify how varying nitrogen application rates and amounts of drip irrigation after sowing influence productivity and resource efficiency in a maize-soybean strip intercropping system, offering a theoretical framework for improving water-nitrogen management in the Huang-Huai-Hai area. 【Method】 From 2023 to 2024, a three-factor orthogonal experimental design was conducted, featuring three cultivation methods: maize alone (M), soybean alone (S), and maize-soybean strip intercropping (MS). The nitrogen levels tested were 120 kg·hm^-2 (N1), 180 kg·hm^-2 (N2), and 240 kg·hm^-2 (N3), while post-sowing irrigation was applied at 0 mm (I1), 30 mm (I2), and 60 mm (I3). This study systematically analyzed the impacts of these planting patterns on leaf area dynamics, yield, water use characteristics, and economic benefits of water and nitrogen regulation. 【Result】 The leaf area index (LAI) for both maize and soybean reached its maximum around 90 days after sowing, following a sine function trend (goodness-of-fit R²>0.967). The MS method notably enhanced maize LAI but reduced soybean LAI. Soybean was particularly responsive to water availability; the lack of post-sowing irrigation (I1) led to a significant decrease in LAI for both S and MS soybean by 13.25%-25.00% and 17.73%-24.48%, respectively, at 30 days after sowing. The most effective intercropping treatment (MSN1I2: low nitrogen at 120 kg·hm^-2+30 mm irrigation) yielded 9 063-9 088 kg·hm^-2. Although this yield was 3.48%-4.11% less than the highest yield from maize monoculture (MN2I3: 180 kg·hm^-2 N+60 mm irrigation), its land equivalent ratio (LER) remained above 1 (1.02-1.26), highlighting the benefits of intensified land use. In comparison to maize monoculture, the strip intercropping system enhanced soil water retention in the 0-40 cm plough layer by 1.20%-8.64%. On average, the trip intercropping system improved economic returns by 4.11%-8.04% and 49.62%-63.28% compared with maize and soybean monocultures, respectively, with the MSN1I2 treatment yielding the highest benefit of 23 638 yuan·hm^-2. This treatment (MSN1I2) showed a synergistic improvement in water and nitrogen efficiency, with an irrigation water productivity of 3.06 kg·m^-3. 【Conclusion】 In the maize-soybean strip intercropping system, lowering nitrogen application to 120 kg·hm^-2 along with 30 mm of post-sowing drip irrigation (MSN1I2) could optimize canopy structure, maintain high and stable yields, enhance economic returns, and improve water and nitrogen efficiency. This approach offered the valuable technical guidance for regional initiatives aimed at reducing nitrogen and enhancing efficiency.
