摘　　要：对影响大花蕙兰开花的5个主要因素———光照、温度、浇水、施肥和留芽模式进行了研究,结果表明:5月至10月中旬用50%遮阳网遮光,有利于大花蕙兰的生长发育,可促进花芽的形成;7—9月在海拔900 m的山区进行催花越夏栽培,为大花蕙兰的生长提供了一个凉爽的气候条件,使其花芽的形成和生长得以顺利进行;6月上中旬给予10～15 d的干旱处理,使兰株处于严重缺水状态,有益于大花蕙兰的花芽分化;5月底增加磷钾肥比例,减少追施氮肥,有利于花芽的分化和生长;成龄苗在上年10—11月留芽,可使假鳞茎得到充分发育,提高大花蕙兰的开花率。The effect on five main factors of Cymbidium hybridum flower, light, temperature,irrigation, fertilization, and patterns of reserved buds were studied. The result showed： sunlight was blinded by 50% sunshading net from May to the middle ten days of October, it favoured the growth of Cymbidium hybridum and to promote the formation of flower bud; Cymbidium hybridum was cultured in hilly area of an elevation of 900 metres, to provide the cool weather condition, and to enable the formation and growth of flower bud to advance smoothly; Cymbidium hybridum was not irrigated for 10 - 15 days during the first-middle twenty days of June, to cause the plant lacking-water, and to benefit differentiation of flower bud; The ratio of phosphorus and potash fertilizer was multiplied and the ratio of nitrogenous fertilizer was decreased during the last ten days of May,to benefit differentiation and growth of flower bud; The bud of mature plant was reserved during last-year October to November, to enable the bulb of Cymbidium hybridum to develop fully and to raise the flower ratio of Cymbidium hybridum.
