实行西部经济大开发 ,水资源是制约的首要因素。要改善西部农业生产条件 ,加快生态环境建设 ,促进国民经济的发展 ,就必须在分析水资源利用现状的基础上 ,研究提出西部旱作农业抗旱节水的调控技术与途径 :加强水资源管理 ,建设节水型农业 ,从水资源时空调节角度出发 ,通过工程调水实现区域调节 ,建设库窑实行年季调节 ,拦蓄径流集雨补灌 ,充分利用自然降水 ,防止水土流失 ,增加覆盖防止蒸发 ,合理耕作促进根系深扎 ,最大限度地提高旱农区的水分利用率和利用效率 ,是西部旱作农业的根本出路。
In carrying out the large-scale economic development in the western region, water resources are the primary factor restricting it. To improve the conditions of agricultural production in western China, speed up the construction of ecological environment and promote the development of national economy, we must study and propose the regulation and control techniques and ways of drought-resistant and water-saving in dry farming in Western China based on the analysis of the present situation of water resources utilization: to strengthen the management of water resources, The construction of water-saving agriculture, water and land from the point of view of space-time regulation, through the project to achieve regional regulation of water transfer, construction of kiln implementation of the annual adjustment, intercept rain catchment catchment irrigation, full use of natural precipitation, prevent soil erosion, increase coverage to prevent evaporation, Reasonable farming to promote deep roots, to maximize the water use efficiency and utilization efficiency of dry farming areas, the western dry farming is the fundamental way out.
