为探讨淮安市不同类型粳稻品种机插标准化育秧技术，以淮稻11号和甬优2640为材料，研究了播种量对机插粳稻秧苗素质和大田栽插质量的影响。结果表明，常规粳稻在120~130 g/盘、杂交粳稻在80~90 g/盘的播种量（干种）下，所育秧苗素质较好，不仅秧苗成毯效果佳，且大田的移栽质量更高。

In order to promote the technology of cultivating the standardized seedlings with mechanized transplanting rice in huai’an, the effects of sowing rate on seedling quality and transplanting quality of machine transplanting japonica rice were studied in this study, using Huaidao 11 and Yongyou 2640 as materials. The results showed that the seedling quality and transplanting quality were better, with conventional japonica rice seeding rate between 120 g to 130 g/plate and hybrid japonica rice seeding rate between 80 g to 90 g/plate.
