黄淮海区域夏玉米生育期水分供需矛盾与抗旱种植技术研究

Study on Contradiction Between Water Requirement and Supply During Corn Growth Stage and Drought-resistant Planting Techniques in Huanghuaihai Region

通过分析黄淮海地区的水资源供需现状,阐述了夏玉米产量与降水的关系及夏玉米耗水量和耗水规律,并提出了结合中长期天气预报、秸秆覆盖和"双行交错"种植技术等措施,为解决黄淮夏玉米高产过程中水分利用等问题提出了新思路。

Based on analysis of supply and demand status of water, the relationship between yield of summer maize and precipitation, water consumption and water consumption pattern were summarized. The measures including medium and long term weather forecast, straw mulching and the technology of double interleaved row sowing, which provide new ideas for solving water utilization in the process of summer maize＇s high output in Huanghuaihai region.
