摘　　要：研究以三系杂交中稻组合农香优676为试验材料,采用裂区试验设计,密度为主区,基本苗为副区,对农香优676润湿育秧移栽的最适密度和基本苗进行了探讨。结果表明:农香优移栽密度为16.7 cm×26.7 cm,基本苗为每蔸插2粒谷秧时,综合表现最好,实际产量最高。Taking Nong - Xiangyou 676 as test material, using the split plot experiment design. The main plot was denstity, the split plot was basic seedings . There were three levels for transplanting denstity and basic seedings per hill, they were 16.7 cm ×20 cm, 16. 7 cm ×26.7 cm, 16.7 cm × 33.3 cm and one, two, three seedlings per hill respectively. The results showed the comprehensive performance were the best and the actual yield was the highest under the denstity and basic seedling per hill were 16.7 cm x 26.7 cm and two seedlings.
