山茶花(Camellia japonica)的花芽分化始于6～7月份,花期在12月至翌年4月间,其中大部分品种的花期在3月份左右。目前,在我国控制山茶花花期的目的,主要是促使山茶花于国庆节期间开放。由于花期提前较多,催花技术难度较大。国内促使山茶花提前开放的方法,通常是用低浓度赤霉素溶液(500～1000ppm)从7月下旬开始,3天一次,连续滴蕾处理,直至国庆前开花时止。这种方法虽对一些品种有效,但处理重复次数繁多,费工、费时、费
Camellia japonica flower bud differentiation began in June to July, flowering in December to the following April, most of which flowering in March or so. At present, the purpose of controlling the flowering period of camellia in our country is mainly to promote the opening of camellia during the National Day. As flowering in advance more, reminder flower technology more difficult. Domestic promotion of camellia early opening method, usually with low concentrations of gibberellin solution (500 ~ 1000ppm) from the beginning of late July, 3 days, a continuous drip bud treatment, until the National Day before the flowering. Although this method is effective for some varieties, but the processing repeated numerous, labor-intensive, time-consuming, fee
