摘要
在农业现代化进程快速推进、水资源供需矛盾日益突出的背景下,水稻田间管理模式面临着向自动化、机械化及节水节肥方向转型的发展要求。为适应现代农业发展需求,水稻旱作栽培技术已得到规模化推广应用。针对目前水稻旱作栽培配套田间管理技术不成熟、水肥管理模式粗放、自动化程度低等问题,通过田间试验对水稻旱作田间水肥药管理技术开展研究,形成一种适用于水稻旱作滴灌水肥一体化管理模式。结果表明,水稻产量7 261.50 kg/hm~2,全生育期灌水12 750 m~3/hm~2,虽与水田栽培用水量和产量相当,但滴灌水肥一体化技术有效提高田间管理机械化程度和水肥利用效率,符合现代农业发展需求。
With agricultural modernization rapid advancement and increasingly prominent contradiction between water resources supply and demand,rice field management mode is facing transitioning development requirements to automation,mechanization,and water and fertilizer saving.To meet modern agriculture development needs,rice dryland cultivation technology has been promoted and ap-plied on a large scale.Aiming at immature field management technology,extensive water and fertilizer management mode,and low automation degree and other problems in current rice dryland cultivation technology.Research on rice dryland cultivation water,fertil-izer and pesticide management technology was carried out through field experiments to form a drip irrigation and integration of water and fertilizer technology management model suitable for rice dryland cultivation.Results showed that dryland rice yield was 7261.50 kg/hm2,irrigation water in whole growth period was 12750 m3/hm2,which was equivalent to paddy field cultivation water consumption and yield.However,drip irrigation and integration of water andfertilizer technology effectively improved field management mechanization degree and water and fertilizer utilization rate,which met modern agriculture development needs.
