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hm^2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 varieties 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 research 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.
