摘　　要：以江苏兴化、姜堰杂交粳稻常优1号、甬优8号"百亩攻关方"与"千亩示范方"为对象,对不同产量水平田块的产量及其构成、群体物质生产与运转等方面进行了比较研究。结果表明:较之高产,超高产群体单位面积总颖花量显著增加,同时保持正常的良好结实性状;群体生育中期的高效光合生长量显著提高;抽穗后群体光合生产力亦显著增强,光合物质的输出与运转更为协调。为实现上述目标,应根据生态区、栽培方式、品种特性等制定相应的超高产精确定量栽培技术以指导实践。Grain yield and its components,dry matter production and translocation of population,etc.of different yielding levels in large-scale(6.7 hm2 and 67 hm2) demonstrative production were researched using japonica hybrid rice varieties Changyou 1 and Yongyou 8 as the materials in Xinghua and Jiangyan,Jiangsu Province.The results showed that the population of super-high yielding had more spikelets per unit area than the population of high yielding and there was no significant difference in the number of panicles,filled-grain percentage and 1 000-grain weight between them.The accumulation of dry matters of super-high yielding population was significantly more than that of high yielding population from jointing to heading,and the same as after heading stage.Quantitative cultivation techniques of super-high yielding in japonica hybrid rice were determined based on different ecological regions,different cultural ways and different cultivar features,etc.
