摘　　要：2006—2011年,对双季超级稻的高产形成规律及配套栽培技术进行了系统研究。研究表明,在保证穗数的基础上提高每穗粒数和结实率、增加中后期的养分吸收和物质生产是双季超级稻高产的关键,与之相对应的高产栽培策略是前期早发、中期壮秆和后期强源。阐述双季超级稻早蘖壮秆强源高产栽培技术体系的内涵,从够苗期、生育前期叶片含氮率和叶色差、一次枝梗分化期大茎蘖数、衰老频度和抽穗后SPAD值下降幅度等方面,提出早蘖壮秆强源的相应群体指标;从移栽叶龄、密度、肥料运筹和水分管理等方面,提出明确的技术指标。实践证明,双季超级稻早蘖壮秆强源高产栽培技术具有高产稳产和提高肥料利用率的显著效果。The laws of yield formantion and the cultivation techniques for double super rice were studied from 2006 to 2011. The results showed that the key for double super rice to obtain high yield is enhancing spikelets number per panicle and seed setting rate based on a suitable panicle number and adding the mass accumulation and the nutrition uptake of the late growth stage. The corresponding high yielding cultivation strategy is promoting an early growth and quick tillering in early stage, getting a strong stalk in middle stage and for- mation a high intensity source in late stage. On this basis, the connotation of the framework ＇ Zaonie, Zhuanggan and Qiangyuan＇ of double cropping super rice was defined, the diagnostic indicators of rice population such as the seedling age of getting enough tillers, nitrogen contents and eolour difference of the leaves in early growth stage, big tillers number in primary launch initiationstage, senescent frequency, decline rate of the SPAD in leaves after heading were put planting, density, fertilizer application, tion technique ＇ Zaonie, zhuanggan and forward, the technical indicators such as optimum leaf age for transwater management were presented. Practice has proved, the cultiva- Qiangyuan ＇ of double cropping super rice were benefit for obtaining a high and stable yield and increasing the fertilizer use efficiency.
