“度·日”催花法,是一种催花新技术。“度”即温度单位,代表温度,“日”即天数。当确定催花温度后,可用它预算出催花期(天数);也可在一定限期内,用它计算出催花所需温度。该催花技术是根据积温原理,用“度·时”(“时”即小时)计算法进行试验才取得成功的。为简化起见,从1990年起改用“度·日”计算法,同样显示了它的可行性。特别是在1993年水养朱顶红的催花中,又经过了高难度的验证。 “Degree · day” reminder flower method, is a new technique of reminding flowers. “Degree” is the temperature unit, on behalf of the temperature, “day” that is the number of days. When determining the temperature after the flower, it can be used to estimate the flowering period (days); also within a certain period of time, use it to calculate the required temperature forcing flower. The flower-promotion technique is based on the principle of accumulated temperature and is tested successfully with the “degree-hour” (“hour”) hour calculation method. For the sake of simplification, switching to the “degree · day” method from 1990 onwards has also shown its feasibility. Especially in the hydroponic aphrodisiac flowers in 1993, and after a difficult test.
