分析研究两系杂交水稻两优培九在气候迥异的不同年型间生育期与产量的温光效应规律。结果表明 :其生育期长短主要受积温 (>0℃ )所控制 ,在中国扬州地区其全生育期为 1 60d左右 ,约需积温为 3 880℃ ;产量因播期、年份不同而呈极显著差异 ,且存在互作效应 ;两优培九在扬州地区安排在 4月下旬至 5月上旬种植 ,有利于高产、稳产。
Analysis of the effects of temperature and light on the growth and yield of two-line hybrid rice “Liangyoupeijiu” in different climates with different climates. The results showed that the length of its growth period was mainly controlled by accumulated temperature (> 0 ℃). The full growth period was about 60 days in Yangzhou, China, and the accumulated temperature was about 3 880 ℃. The yield was very significant due to different sowing dates and years Differences, and there is an interaction effect; Liangyou Peijiu arrangements in Yangzhou in late April to early May planting, is conducive to high yield and stable yield.
