对高产与超高产水稻产地的环境因子、生长发育、物质积累、产量形成等因素进行比较研究，超高产水稻在有效穗数、穗粒数和千粒重、ＬＡＩ高值持续时间、干物质积累总量等方面优于高产水稻。７～９月份超高产水稻所处环境的太阳辐射总量、最高温分别比高产环境高２５．７％和２１．３％。形成大穗、多穗的遗传力小，其决定时期无光温明显差异，因而改变栽培管理措施来增加高产水稻的有效穗粒数和穗粒数至超高产水平是客观可行的。粒重形成的遗传力较大，选用千粒重较高的品种可以弥补高产水稻所处环境下８、９月份光温的略微不足。笔者认为：第一，在５、６月份采取适当措施增加有效穗和延长穗分化时期以利形成大穗；第二，在８、９月份采取营养调控等措施延长高产水稻ＬＡＩ高值持续期，增加其干物质积累量，有可能使高产水稻产量上升到超高产水平
The factors such as environmental factors, growth and development, material accumulation and yield formation of high and super-high yielding paddy producing areas were comparatively studied. The results showed that there were significant differences in the number of panicles per panicle, the number of grains per panicle and 1000-grain weight, the duration of high value of LAI, And so on than the high yielding rice. From July to September, the total solar radiation of super high-yielding rice was 25.7% and 21.3% higher than the high-yielding environment respectively. It is feasible to change the cultivation management measures to increase the effective grains per spike and the number of grains per spike to the level of super high yield in high yielding rice. The heritability of grain weight formation is larger, and the selection of varieties with higher 1000-grain weight can make up for the slight deficiency of light temperature in August and September under the environment of high yielding rice. In the author’s opinion, first, take appropriate measures in May and June to increase the effective panicle and extend the panicle differentiation period to facilitate the formation of large panicle; secondly, adopt the nutrition regulation and other measures in August and September to extend the high-value duration of LAI in high- Increasing the accumulation of dry matter may increase the yield of high-yielding rice to the level of super-high yield
