我省地处干旱地区,雨量稀少,干旱次数频繁,群众有三年一小旱、五年一中旱、十年一大旱的说法。面对干旱,当以兴修水利、扩大农田灌溉面积为要。但我省水利资源有限,年降水只有300～500毫米,地面水、地下水资源奇缺,目前开发几达最大限度,潜力是不大的。因此发展我省农业的根本途径,就在于采取针对性措施,因地制宜地实行旱作农业。我 The province is located in arid areas, rainfall is scarce, frequent droughts, the masses have a small drought in three years, a drought in five years, a drought in ten years. In the face of drought, it is necessary to expand water conservancy and expand irrigated farmland. However, our province has limited water conservancy resources, annual rainfall is only 300 ~ 500 mm, surface water, groundwater resources are scarce, the current development of up to a maximum of up to potential is not large. Therefore, the fundamental way to develop agriculture in our province lies in adopting pertinent measures and implementing dry farming in line with local conditions. I
