发展旱作农业节水工程技术,高效利用有限水资源,对于保障粮食作物稳产高产具有长远和现实的双重意义。阐述旱作农业工程节水技术的内涵,介绍目前应用较为普遍的少免耕覆盖机械化技术、农田耕作蓄水保墒技术、秸秆粉碎还田技术、节水灌溉技术、水改旱技术5种技术内容,为旱作农业工程技术推广提供借鉴。
The development of dry farming water-saving engineering technology, efficient use of limited water resources, to ensure stable and high yield of food crops has long-term and realistic dual significance. Describe the connotation of water saving technology for dry farming agriculture, and introduce the five kinds of technical contents of less-tillage mechanization technology, farming tillage and soil moisture conservation technology, straw crushing and returning to field technology, water-saving irrigation technology and water-to-drought technology, , To provide reference for popularizing agricultural engineering technology.
