摘要： 以东农428和龙稻5号为试验材料，对不同栽培模式下东北粳稻光合物质生产特征进行研究。结果表明，适宜垄距下采用高光效栽培模式，水稻的干物质积累、运转及叶面积、光合势等物质生产和光合生产特征明显优于其他栽培模式，其成熟期群体干物质量和产量比常规栽培分别高1.75~2.51 t/hm2和2.66~3.78 kg/30 m2。同为高光效栽培模式，（20+40） cm×15 cm的垄距处理其成熟期群体干物质量和产量明显高于（20+50） cm×15 cm的垄距处理，分别高2.00~2.67 t/hm2和2.91~4.95 kg/30 m2，说明行距超出适宜范围其群体干物质积累反而下降，不利于水稻高产群体的形成。

Abstract: Dongnong 428 and Longdao5 were used as test materials to research the characteristics of photosynthesis and matter production of japonica rice in Northeast China under different cultivation mode. The results showed that, under the appropriate ridge distance, the material production and photosynthetic characteristics of high-light-efficiency cultivation mode such as the dry matter accumulation, transportation, leaf area, photosynthetic potential were better than those of other cultivation modes, and the group dry weight and yield at the maturing stage were 1.75~2.51 t/hm2 and 2.66~3.78 kg/30 m2 higher than conventional cultivation. The group dry matter weight and yield of （20+40） cm×15 cm ridge distance treatment were significantly higher than those of （20+50） cm×15 cm ridge distance treatment under high-light-efficiency cultivation mode, increased by 2.00~2.67 t/hm2 and 2.91~4.95 kg/30 m2 respectively. It suggested that accumulation of group dry matter would decrease when the ridge distance was beyond the suitable range, and not conducive to the final formation of high yield population of rice.
