摘　　要：试验研究“新红花 1号”和“新红花 2号”光温指数对其生育期及产量的影响结果表明 ,出苗～分枝日数与光温指数呈负相关 ,与生育期呈正相关。生育期与光温指数、密度呈反相关。产量与光温指数密切相关 ,光温指数为 14 0～ 150时相对产量为 90 %以上。光温指数与出苗日期呈良好正相关 ,最佳出苗日期为 4月 6～ 2 7日 ,种植密度为 16.5万株 /hm2 时其相应生育期 10 8～ 12 5d ,种植密度为 3 0万株 /hm2 时则生育期为 93～ 110d。The effects of reasonable sunshine-hour and temperatu re index on the duration period and output of “New safflower 1” and “New safflo wer 2” are studied in this paper.The results show that the major influences of emergence of seedlings are temperature and soil humidity;number of days of seedl ings～ramification and index of reasonable sunshine-hour and temperature are ne gative correlative;number of days of seedlings～ramification and duration period are positive correlative;duration period and index of reasonable sunshine-ho ur and temperature,density are negative correlative.Output and index of reasonable sunshine-hour and temperature are closely correlative, the relative output is more than 90% when index of reasonable sunshine-hour and temperature is in 140 ～150.Number of days of emergence of seedlings and index of reasonable sunshine -hour and temperature are in good correlation in Xinhe and Fuhai,the optimum em ergence of seedling date is on 6～27 April.Its homologous duration period is 108 ～125 days when the density is 165 thousand zhu/hm 2 and is 93～110 days when t he density is 300 thousand zhu/hm 2.
