摘　　要：在分析国内外旱地农业研究最新进展的基础上 ,就我国半干旱地区旱地农业技术发展趋向进行了论述 ,认为保护性耕作、有限灌溉、遗传改良、化学调控是今后我国旱农技术研究与发展的几个重要方面 ,并对此提出了若干看法与建议。The developmental tendency of dry land farming technologies in the semiarid area of China was evaluated based on the analysis of current progresses of dry land farming researches both in China and worldwide. It was emphasized that conservation tillage, limited irrigation, genetic modification and chemical contol were the important aspects for the dry land farming research and development in the future. Some viewpoints and suggestions were proposed in this paper.
