摘要
根据连续七年对再生稻的生态条件进行的系统研究，结合四川省１９８９～１９９２年生产统计资料和四川省气象局的地面气候资料，探讨了品种、头季稻播种期、头季稻收后３０天积温、温湿度、光照以及海拔高度对再生芽萌发、再生稻齐穗以及产量的影响。提出了再生稻的生态值，据此生态值确定了其适应区域。
According to 7 year's continuous studies on the ecological conditions of ratooning rice, the production area in 1989 1992 in Sichuan Province and the climate information provided by Sichusn Meteorological Bureau, the influence of variety, sowing date of the first crop, 30 day's accumulated temperature after first crop harvesting, temperature and humidity, irradiation and altitude on the germination of regenerated bud, heading stage and yield of ratooning rice were discussed. Ecological index for planting ratooning rice was put forward and suitable zones for ratooning rice planting were worked out.
