文章针对天津市水资源短缺,特别是春季冬小麦生长季可用水源少及生产中氮肥施用量较大的现状,运用节水、省肥、高产、简化“四统一”栽培技术体系原理,在天津地区研究制定了冬小麦节水省肥高产简化栽培技术,在实践中取得良好效果,有适度低投入、高效高产出的特点。该技术提出了品种选择原则、产量目标和灌溉、施肥的指标,有较强的实用性,可在天津地区轻壤和中壤土质麦田大面积推广。
In this paper, aiming at the shortage of water resources in Tianjin, especially the shortage of available water in the growing season of winter wheat and the large amount of nitrogen fertilizer used in production, the paper uses the principle of water saving, fertilization, high yield and simplification of “four unified” Tianjin region developed a winter wheat water-saving fertilizer high-yielding and simplified cultivation techniques, and achieved good results in practice, with moderately low input, high efficiency and high output characteristics. The technology put forward the principle of variety selection, yield target and index of irrigation and fertilization. It has strong practicability and can be widely popularized in light soil and medium loamy wheat field in Tianjin.
