摘　　要：为了探明江淮地区的温光资源对杂交中籼水稻的秧苗素质、生育进程、茎蘖动态、田间抗性及产量构成的影响,通过选用不同熟期不同品种的杂交中籼水稻,设置不同的播、栽期,明确江淮地区高产优质的杂交中籼水稻的适宜播期。结果表明,5月15日以后播种的品种,随着播期的推迟,品种的生育进程延后、茎蘖数减少、产量降低,所以,杂交中籼水稻在江淮地区的播期不能迟于5月15日以后,适宜播期是4月15日—5月15日。To find out how the temperature and light resources in Jinghuai Region influence the seeding quality, growth process, tillering dynamics, field resistance and yield components of medium indica hybrid rice, the authors selected and used medium indica hybrid rice with different breeds and different mature period. By planting them in different time, the authors identified the appropriate planting period of the medium indica hybrid rice with high yield and quality in Jinghuai Region. The results showed that the rice planted after May 15th, with delay of planting date, had longer growth process, fewer tillers and lower yield, so the medium indica hybrid rice shouldn＇ t be planted after May 15th in Jianghuai Region, the most appropriate planting period was from April 15th to May 15th.
