摘要

节水抗旱稻以较强的耐旱性、丰产性，对轻简栽培和机械化生产的适应性，成为棉田改种和水资源不足稻田的高效种植选择。在湖南省的需求面积至少在40万hm2以上，并呈逐步扩展之势。该文提出了选育和引进适应湖南省栽培的节水抗旱稻品种、研究推广配套的栽培技术规范，提高农民种植效益的技术策略。%Water-saving and drought-resistance upland rice has become a preferable choice for cotton farmlands ready for changing crops or paddy fields with water in short, because simplified and mechanical cultivation can be applied for the rice vari-eties of drought resistance and high yield. At present, it has been applied with an area of 400 000 hm2 in Hunan Province and the area continues growing. The re-search bred and introduced the relevant cultivation technology standard applicable to local water-saving and drought-resistance rice varieties in order to improve farmer's benefits.
