摘要
在有限水资源下实现张杂谷等杂交谷子节水高产及水资源的合理利用,可为我国粮食安全及农业的可持续发展做出贡献。从谷子及杂交种的抗旱节水特点、水分利用特性、现阶段以地膜覆盖为主的节水技术以及节水机理3个方面阐述了当前研究进展。并根据张杂谷等杂交种生产特点和区域特性,提出谷子以及张杂谷等杂交种未来提高水分利用效率的问题和研究重点。主要包括旱区雨水高效利用、半干旱区调亏灌溉、高水效品种以及综合节水研究等。为谷子以及杂交种发展和种植区域扩大提供参考。
Under the limited water resources, realization of water-saving high-yield of hybrid millet and the rational use of water resources can contribute to food security and the sustainable development of agriculture. This paper describes the current research progress from three aspects, respectively, including the drought resistance and water saving characteristics, the water saving technology and mechanism with the main way of plastic mulching of the millet and hybrid millet. According to the characteristics and regional features of the millet and hybrid millet Zhang or the other hybrid cultivar, this paper puts forward the problems and the research key of improving water use efficiency for millet and hybrid millet Zhang in the future, including the high rainwater use efficient in arid, the regulated deficit irrigation in semi arid areas, high water efficiency variety and the integrated study on water saving. It will provide reference for millet and hybrid millet development and the expansion of planting area.
