摘要： 以南粳9108为试验材料，在印刷播种和常规播种方式下，探讨不同栽插密度对毯苗机插水稻产量及其光合物质生产特征的影响。结果表明，与常规播种相比，印刷播种方式下水稻增产1.9%~6.3%，差异显著；长生育期、大群体颖花量和高干物质积累量是印刷播种方式水稻增产的重要途径；适当降低栽插密度可使印刷播种方式毯苗机插水稻获得高产，行株距30.0 cm×13.0 cm是印刷播种方式水稻获得高产的较优配置。

Abstract: The effects of different sowing method and planting density on the yield and photosynthetic production of machine transplanting rice were studied, using Nangeng 9108 as material. The results showed that, compared with conventional sowing method, the yield of printing-sowing method was increased by 1.9%~6.3% significantly, which depended on the long growth period, great amount of spikelets in population and higher accumulation of dry matter. The suitable low planting density was easier to acquire higher yield under printing-sowing method with machine transplanting, and the best plant spacing was 30.0 cm ×13.0 cm.
