夏菊的成花因素和二次开花的特性,早已为人所知。但夏菊可以多次开花的特性,人们却不一定了解。我们杭州花圃经过5年(1992～1997年)的栽培,发现夏黄一号品种不仅可二次开花,还能多次开花,具有非常突出的连续开花特性,是切花夏菊中一枝新秀,值得进一步研究和开发。夏菊的成花对光周期要求不严,属中性反应,但对温度要求很高,只要积温够了,就可开花。在保护地常规种植情况下,最早现蕾期在3月中上旬,盛花期在4月上中旬。尾花结束后,接着短截处理,又可孕育二次花。全部生育期只有短短的3个月,这是夏黄一号最省工、省时、供花早的一个特点。尤其值得指出的是,在短截
The flower formation factor and the secondary flowering characteristics of the summer flower have long been known. However, the characteristics of flowers can bloom many times, people do not necessarily understand. After 5 years (1992 ~ 1997) cultivation in our flower garden in Hangzhou, we found that the Xiahuang No.1 variety not only can be used for secondary flowering but also for many times. It has the outstanding continuous flowering characteristics and is a rookie among the cut flowers. It deserves further study And development. The flower of summer chrysanthemum on the light cycle of lax requirements, is a neutral reaction, but the temperature is very high, as long as the temperature is enough, you can flowering. In the protected areas of conventional planting, the earliest budding period in early March, full bloom in mid-April. After the end flower, then short cut, but also secondary flower. All the growth period of only a short period of 3 months, this is the summer on the 1st most labor-saving, time-saving, early flower for a feature. Especially worth noting is that in the short cut
