综述了近年有关中国超级杂交水稻的栽培特性和生态适应性的研究结果.指出目前已育成的超级杂交水稻在中国南方多种生态区域作-季稻栽培,产量可达12 t/hm2,生育期130～150 d,颖花量5.5～6.0万/m2,叶面积指数9～10,株高100～110 cm,分蘖力偏强,表现出足穗大穗、源库协调、耐肥抗倒的潜在高产优势.通过对超级杂交水稻的生长发育、光合生产及其分配、分蘖及其成穗、根系生长及其活力、适宜种植区域及其栽培期、超高产途径与技术体系等方面的研究,初步明确了单本稀植、增施氮肥条件下产量形成的生理基础、栽培环境和农艺调控技术.为了充分发挥超级杂交水稻的高产潜力,有必要对其足穗大穗与高结实率相...

This paper is an attempet to summarize the results of high yielding cultivation researches on super hybrid rice in recent years and point out the single rice culture of China super hybrid rice under different ecological conditions in the south of China. China super hybrid rice has the yield 12 t/hm~2, growth duration 130-150d, spikelet number 5.5×10~4-6.0×10~4/m~2,LAI 9-10, plant height 100-110 cm and stronger tillering ability, which shows the potential yield heterosis with adequate panicle number, large panicles, good coordination between s...
