节水抗旱稻在湖南的发展前景与策略

Development Prospect and Strategies of Water-Saving and Drought-Resistance Rice in Hunan

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。国内多家育种单位培育的一系列节水抗旱稻品种,但湖南省内尚未有育成品种或栽培技术研究。为此,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,即:加强节水抗旱稻新品种引进筛选,加强节水抗旱稻新品种选育,加强节水抗旱稻种植技术研究与推广。

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. A series of water-saving and drought-resistant rice varieties were cultivated by the domestic breeding units. But there is no relative report on bred varieties and cultivation techniques in Hunan Province. It was proposed that breed and introduce water-saving and drought-resistance rice varieties suited to Hunan conditions, research and generalize the relevant cultivation technology to improve farmer＇s benefits.
