红花光温指数对其生育期及产量的影响研究

lndex 0f reasonable sunshine-hour and temperature and its effect on growth period and output of Safflower

  • 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140~150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6~27日,种植密度为16.5万株/hm2时其相应生育期108-125d,种植密度为30万株/hm2时则生育期为93~ll0d。

     

    Abstract: The effects of reasonable sunshine-hour and temperature index on the duration period and output of“New safflower 1”and “New safflower 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 seedlings~ramification and index of reasonable sunshinehour and temperature are negative correlative;number of days of seedlings~ramification and duration period are positive corre1ative:duration period and index of reasonable sunshine-hour and temperature,density are negative correlative.Output and index of reasonable sunshine-hour and temperature are closely corelative,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 corelation in Xinhe and Fuhai,the optimum emergence of seedling date is on 6~27 April.Its homologous duration period is 108~125 days when the density is 165 thousand zhu/hm2 and is 93~110 days when the density is 300 thousand zhu/hm2
