【Abstract】 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.更多还原
