旱作农业就是在难以供水的旱地,通过发挥人的主观能动性,应用综合配套技术,挖掘自然降水利用率的生产潜力,实现旱作稳产高产的农业生产活动。选用推广抗旱品种,是发展旱作农业的前提,调整旱地作物结构和产业结构,是顺天时应地力,趋利避害发展旱作农业的关键;培肥改土,以肥调水是旱作基本农田地力建设的重点;秸秆还田是培肥改土的重要途径,以集径流蓄水抗旱栽培为主的技术,可对旱作农区有限降
Dry farming is the dry land that is difficult to supply water. By exerting subjective initiative of human beings and applying integrated supporting technologies, the productive potential of natural rainfall utilization can be tapured to realize the stable and high-yielding agricultural production in dry farming. The selection and promotion of drought-resistant varieties is the prerequisite for the development of dry farming. Adjusting the crop structure and industrial structure of dry land is the key to improving soil fertility while avoiding disadvantages and developing soil-saving agriculture. The key point of soil fertility construction of basic farmland is that straw returning is an important way to cultivate soil and improve soil fertility,
