一、温度对切花月季开花的影响切花月季栽培最适宜的温度,白天是20—25℃晚上13—16℃,25℃以上生产和开花速度加快,30℃以上的高温和潮湿的气候下开花不良,易发生病虫害。在高温干旱的条件下,出现落叶和休眠;5℃以上低温还能继续缓慢生长和开花;5℃以下则处于休眠状态。月季从发芽到开花需要一定的积温,积温高低因品种而异,一般在700—1000℃以上。温度高,积累
First, the temperature on the flowering of cut rose Rose flowers the most suitable temperature for cultivation, the day is 20-25 ℃ at night 13-16 ℃, 25 ℃ above the production and flowering speed, 30 ℃ above the high temperature and humid climate, poor flowering , Prone to pests and diseases. In high temperature and drought conditions, there are deciduous leaves and dormancy; low temperature above 5 ℃ can continue to slow growth and flowering; below 5 ℃ in a dormant state. Rose from sprouting to flowering requires a certain amount of accumulated temperature, accumulated temperature varies by species, generally above 700-1000 ℃. High temperature, accumulation
