摘　　要：[目的]探讨迟熟中粳新品种宁粳7号在安徽滁州地区的栽培特性和技术。[方法]以宁粳7号为材料,从不同播期试验、机插秧不同播量试验、机插秧不同密度试验、播量和密度交互试验等方面进行研究。[结果]宁粳7号6月份播种,产量降低显著,机插秧播种量75、100 g/盘时产量较高;宁粳7号机插秧中播种量100 g/盘,配合移栽株距11 cm时产量最高。[结论]宁粳7号在安徽滁州地区适宜播期为4月下旬—5月下旬,机插秧移栽行距固定为30 cm时,适宜播种量为100 g/盘,移栽株距11 cm。[ Objective]To explore the high yield cultivation characters and techniques of Ningjing 7 in Chuzhou, Anhui Province. [ Method] With Ningjing 7 as the test material, the different sowing date test, different density and sowing amount tests of machine-transplanted seedling, and density and sowing amount interaction test were carried out. [Result] When Ningjing 7 was seeded in June, the yield was reduced signifi-cantly. When the sowing amount was 75 and 100 g/dish in machine-transplanted seedling, the yield was relatively high. In addition, the yield was the highest when the sowing amount was 100 g/dish and plant spacing was 11 cm. [ Conclusion ] The suitable sowing date for Ningjing 7 in Chuzhou was from late April to late May. When the rowing space was fixed to 30 cm in machine-transplanted seedling way, the suitable sowing amount was 100 g/dish and plant spacing for transplanting was 11 cm.
