每当盛夏来临,色型俱佳的现代月季,不论花色、花型、花瓣数,花朵大小和生长势都较春、秋逊色,是令人颇感遗憾的问题。要解决月季度夏问题,应以它的生长习性来分析成因。初春,当温度回升(6～8℃)时芽点萌动。(如在此时期内受到寒流冷风的侵袭,轻者发生大量雄条,重者发生抽条死芽现象)发育的最适温度:白天18～25℃,夜晚10～15℃,相对湿度75～80％,大约经6～7周开花。春秋季节由于昼夜温差和光照强度适宜,使枝条发育充实,花头发育完美。在保证4～5个小时有效光照时即可发育。在10个小时以上的光照时仍可
Whenever Midsummer is approaching, modern Chinese rose, regardless of color, flower pattern, number of petals, flower size and growth potential, is more regrettable than spring or autumn. To solve the problem of the summer moon, it should be its growth habits to analyze the causes. In early spring, when the temperature rises (6 ~ 8 ℃) bud germination. (Such as during this period by cold and cold invasion, the light a large number of male sterility, severe occurrence of sprouting die bud) the optimum temperature for development: during the day 18 ~ 25 ℃, night 10 ~ 15 ℃, relative humidity 75 ~ 80%, about 6 ~ 7 weeks after flowering. Spring and autumn season due to temperature difference between day and night and light intensity appropriate, so that branch development enrichment, perfect flower development. In 4 to 5 hours to ensure effective light when the development. In more than 10 hours of light can still be
