根据月季开花与积温、日照相关性的研究,发现在诸多的环境因子中,温度是影响月季生长的重要因子。月季生长的最适温度为白天20～25℃,晚上12～16℃,30℃以上生长不良,5℃以下的低温则处休眠状态。在满足一定质的温度阶段和量的温度达到一定积温后才能促使月季开花,一般有一个阶段晚上达到14～16℃才能形成花蕾,低于10℃盲花率提高。一、积温与花期的关系:积温高低因品种而有差异,因此,控制花期应根据不同品种开花所需的积温,在确保良好的肥水条件和适宜温度的极限范围内,按当时日平均温度或设施能达到温度来推算修剪日期。如‘金奖章’开花要求积温710℃左右;‘唐娜小姐’开花要求积温765℃左右;‘白卡片’开花要求的积温在790℃左
According to the study on the correlation between flowering and accumulated temperature and sunshine, we found that among many environmental factors, temperature is an important factor affecting the growth of roses. The optimum temperature for the growth of roses is 20-25 ° C during the day, 12-16 ° C at night, poor growth above 30 ° C, and dormant at low temperatures below 5 ° C. To meet certain temperature and temperature of the amount of temperature reaches a certain accumulated temperature to promote the flowering of roses, usually a stage reached 14 ~ 16 ℃ to form flower buds, less than 10 ℃ blind flower rate increased. First, the relationship between accumulated temperature and flowering: the accumulated temperature varies with the species, therefore, flowering control should be based on different varieties of flowers required for the accumulation of temperature, to ensure good fertilizer and water conditions and temperature limits within the appropriate mean daily temperature or The facility can reach temperature to figure out the trimming date. Such as the ’Gold Medal’ flowering requires accumulated temperature 710 ℃; ’Miss Donna’ flowering requires accumulated temperature 765 ℃; ’white card’ flowering required accumulated temperature at 790 ℃ left
