2022年11月23日 · These results demonstrate that the optimized irrigation quota (540 mm) can effectively improve the growth, yield, and WUE of drip irrigation maize in northwest China. Meanwhile, it can provide a theoretical reference and data support for the optimal amount of irrigation for drip irrigation maize in Xinjiang China. 1. Introduction.

2024年5月31日 · To investigate the effects of regulated deficit irrigation (RDI) at different growth stages on maize yield and WP, a 4-year field experiment was conducted on spring maize under film drip irrigation from 2016 to 2019 in an arid region of northwest China. RDI significantly reduced plant height, leaf area index (LAI) and dry matter accumulation (DM).

2025年1月8日 · Under the 1.5 °C (3 °C) warming scenario, this approach involves increasing irrigation water withdrawals for maize by 62% (67%) and reducing it for soybean by 65% (58%), while increasing...

2023年5月24日 · A 7-year field study from 2015 to 2021 evaluated the effects of drip irrigation (DI, 540 mm) or conventional border irrigation method (BI, 720 mm) on maize growth, water use efficiency (WUE)...

4 天之前 · Maize was irrigated with a central pivot when the soil water content was below 50% of the field capacity. The estimation of the available water derived from the difference between gravimetric moisture at field capacity (0.32 g water g soil − 1 ) and gravimetric moisture at permanent wilting point (0.16 g water g soil − 1 ) (Batallanez 1972 ).

2024年8月1日 · Over-input of nitrogen (N) fertilizer coupled with flood irrigation resulted in low N and water productivity and serious NO3--N leaching in maize fields in the North China Plain (NCP). Drip-fertigation can enhance water-N use efficiency by precisely regulating water and N fertilizer application.

2 天之前 · In this field experiment with maize, the Zhengdan 958 variety was sown on the day of year (DOY) 170 in 2023. At the early growth stages of the maize, irrigation was precisely controlled to maintain similar soil moisture conditions across all the experimental plots, thus ensuring consistent initial growth conditions.

2023年1月28日 · Increasing water-use efficiency by optimizing planting density and irrigation regimes in maize is crucial for food security under limited water resources.

2023年7月26日 · Subsurface drip irrigation (SDI) system combined with nitrogen management under conservation agriculture-based (CA) maize-wheat system (MWS) effects on crop yields, irrigation water...

2024年1月20日 · Application of nitrogen rates of 250 kg ha −1 under irrigated conditions is the best choice to increase grain yield, improve nitrogen use efficiency, and ensure safe and efficient production in maize. The rapid increase in population has led …
