摘　　要：探求能满足高产、优质、高效、生态、安全五个方面综合要求的,先进的、适用的水稻精确定量栽培是水稻栽培科学技术发展的方向,是水稻科学栽培的创新发展。详述了水稻叶龄模式、水稻高产群体质量指标、水稻高产优质群体培育的总途径和分阶段的诊断的定量指标。从播栽期、培育壮秧、合理基本苗、行株距、施肥、水分等方面进行了水稻栽培技术的精确定量。实践证明,水稻精确定量栽培理论与技术体系,具有广泛的指导作用和适用价值。It is the developmental orientation of rice culturing science and technology and the creative development of rice cultivation to explore advanced and suitable precise and quantitative rice cultivation which also meets the five comprehensive requirements, i.e. high yield, fine quality, high efficiency, ecology and security. The authors stated clearly rice leaf age model, rice high-yielding population quality index, general approach to form high-yielding and good quality rice population and quantitative standards for diagnose by stage. The precise quantification of rice cultivation techniques was made in terms of sowing date, sturdy seedling nurturing, rational transplanting seedling number, hill space in row and between-row space, fertilization and water management. Practice proves that rice precise and quantitative cultivation theory and technique system have a wide directing effect and applicable value.
