摘　　要：通过对盐丰47、辽盐166不同插秧密度的对比试验,结果表明:大石桥地区盐丰47、辽盐166品种以30.0cm×(20.0～23.1)cm的插秧密度较好,可节省秧苗30%～50%、增收12～42元/667m2。The comparison experiment of transplanting density in rice varieties, Yanfeng 47 and Liaoyan 166, was conducted. The results showed that the favorable density for Yanfeng 47 and Liaoyan 166 was 30.0 cm ×（20.0- 23.1）cm in Dashiqiao area, which could save seedlings by 30-50% and increase benefits by 12-42 yuan RMB per 667 m^2.
