摘　　要：:1 998年早、晚季 ,在广州测算了两系法杂交水稻强优组合培矮 6 4S/E32、培矮 6 4S/931 1、粤杂 1 2 2和常规优质高产品种粤香占和高产品种特三矮 2号的光能利用率。结果显示 :早季稻的平均光能利用率为 0 .996 %±0 .0 5 9% ,晚季稻为 0 .843%± 0 .0 2 9% ;早季以培矮 6 4S/E32光能利用率最高 ,达 1 .0 6 2 % ,晚季以培矮 6 4S/931 1最高 ,为 0 .877%。Utilization ratio of solar energy for the two line hybrid rice combinations Pei'ai 64S/E32, Pei'ai 64S/9311, Yueza 122 and conventional varieties Yuexiangzhan, Tesan'ai 2 was investigated in both the early and late cropping seasons in 1998 in Guangzhou. The results showed that the average utilization ratios of solar energy in both the early and late cropping seasons were 0.996%±0.059% and 0.843%±0.029%, respectively. Pei'ai 64S/E32 had the highest utilization ratio of solar energy (1.062%) in the early cropping season, while Pei'ai 64S/9311 had the highest utilization ratio of 0.877 % in the late cropping season.
