摘要
旱地农业建设是我国农业生产的重要方面 ,通过对我国旱地农业战略地位和主要特征的分析 ,从持续发展角度 ,提出了旱地农业建设的技术路线 ,总结分析了旱地农业建设的技术途径。指出我国旱地农业建设应以降水的高效利用为中心 ,提高降水利用率、降水生产潜力开发利用率和水分利用效率 。
The dryland farming construction is an important part in china's agriculture. Based on analyzing the strategic position and major chracteristic of dryland farming in China, the paper gives out the technology line. From the idea of sustainable development, the technological system and the approaches of dryland farming construction is analyzed. The paper pointed out that the center of daryland farming construction lies in highly efficient use of rainwater. The technological approaches must be toward raising use rate of rainfall, exploitation use rate of rainfall potential productivity and water use efficiency. The technology of rainwater harvesting as supply irrigation can be expanded, but should also be studied deeply.
