水稻旱种是水稻抗旱播种,节省用水的一种栽培方法。随着商品经济的发展和城乡人民生活水平日益提高,广大群众对细粮的需求越来越迫切。除积极大力发展灌溉种植水稻外,在灌水条件不足或缺水地方,因地制宜地积极发展水稻旱种,是节省灌溉用水,提高灌溉效益,促进粗改细,合理调整种植业结构,扩大水稻种植面积,发展水稻生产的有效措施。由于水稻旱种多数是将水稻种子直接播种在旱田里,主要靠土壤水分、天然降雨和人工辅助旱灌。因此其所用的品种大部是耐旱性强的一些水稻 Cultivation of rice is drought-resistant rice planting, water conservation, a cultivation method. With the development of commodity economy and the increasingly high standard of living of urban and rural people, the demand of the broad masses for fine grains has become more and more urgent. In addition to active and vigorous development of irrigated rice cultivation, in poor irrigation conditions or lack of water, local conditions and actively develop dry cultivation of rice is to save irrigation water, improve irrigation efficiency, promote coarse and fine, rational adjustment of planting structure, expand rice acreage , The development of effective measures for rice production. As the majority of rice dry cultivation is the direct sowing of rice seeds in the dry land, mainly by soil moisture, natural rainfall and artificial irrigation. Therefore, most of the varieties used are some rice with strong drought tolerance
