西北旱地农业研究进展及科技创新重点内容

Advances and Key Innovating Contents of Science and Technology on Dryland Agriculture in Northwest China

西北地区是我国北方旱地农业的重要组成部分,西北旱作区在保障区域粮食安全、绿色生产与生态协调中发挥着特殊的作用与贡献。基于对新时期西北旱地农业战略地位和重大需求的再认识,通过总结西北旱地农业研究取得的主要进展,提出了藏粮于地、藏粮于种、藏粮于水及藏水于技的旱地农业科技攻关思路,认为西北旱地农业科技创新攻关应强化旱地应用基础研究,集中开展旱地农业关键技术和不同应用场景旱地农业技术集成模式的科技创新工作,旨在支撑抗旱增粮科技行动,确保西北区域粮食安全。

Northwestern area is a crucial part for dry farming in northern China,dry farming area in the northwest plays important roles in ensuring regional food security,coordination between green production and ecological protection.Based on the re-understanding of the strategic position and major demands of dryland agriculture in Northwest China in the new period,this paper summarizes the research progress of dryland agriculture,thoughts of food crop production strategies based on farmland management and seeds innovation and water storage on tackling key problems in dryland agriculture are put forward.The scientific and technological innovation of dryland agriculture should strengthen the applied basic research and focus on key technologies tackling and technology integration systems for different application scenarios,so as to supporting yield increase of grain action with drought resistance and ensuring regional food security.
