【摘要】 [目的]人工调控早银桂的花期。[方法]利用桂花对温湿度的敏感性,以早银桂为材料进行低温加湿室内催花试验,通过调控温湿度的手段促使早银桂提前开花。[结果]经过低温加湿的早银桂比露天自然条件下的早银桂花期提前了10 d左右。[结论]低温加湿的方法可以促使早银桂提前开花。更多还原

【Abstract】 [Objective]To artificial regulate the florescence of Osmanthus fragrans ‘Zao Yingui’.[Method]Using the sensitivity of O. fragrans to temperature and humidity, O.fragrans ‘Zao Yingui’ was used as the test material to carry out the flower forcing test with low temperature and humidification.[Result]Under the low temperature and humidification, the O.fragrans ‘Zao Yingui’ flowering period was about 10 days earlier than that under the open natural conditions. [Conclusion]The low temperature and humidification can promote O.fragrans ‘Zao Yingui’ to blossom ahead of time.更多还原
