麦若水稻旱作是采用耐旱品种，在麦收后的旱地上直播，生育期间不保持水层，充分利用自然降水，只进行几次适时浇灌的湿润栽培方法。这在半湿润地区特别是缺水的淮河流域，是种植制度的一项重要改革。其节水、增产、沃土的科学价值重大，具备大面积推广的基本条件和潜力。 Mairuo rice dry cultivation is the use of drought-tolerant varieties in the wheat after the dry land on the broadcast, does not maintain water during growth, make full use of natural precipitation, only a few timely irrigation wet cultivation methods. This is an important reform of the planting system in the semi-humid areas, especially the water-deficient Huaihe River. Its water-saving, increase production, fertile land of great scientific value, with a large area to promote the basic conditions and potential.
