【摘要】 对蓝西、蜜糖、百万金币、红猫、巴黎文心和蜘蛛文心共6个品种的文心兰采用不同的光照、温度、施肥配比和植物生长调节剂处理,发现最适于花芽萌发的光照强度为19000lx,温度条件为(日温～夜温)28～17℃,施肥配比为N:P:K=10:30:20,同时满足这些条件进行催花,蜜糖、百万金币和巴黎文心的抽花率可达70%以上,蓝西、红猫分别为55%和66%。蜘蛛文心的花芽分化必须经过较低温处理,经(日温～夜温)25～15℃处理60d,抽花率达到72.3%。6-BA处理对参试文心兰的抽花率未见明显影响。更多还原

【Abstract】 In this research ,six varieties Oncidium(langxi、honeysugar、milliongolds、redcat、paris oncidium and spider oncidium)were tested by using difference illumination、temperature、fertilization proportionment and plant growth regulator, optimum illumination intension for flower buds’s bourgeon is 19000lx, optimum temperature(day temperature～night temperature) 28～17℃, the optimum proportionment of fertileization:N:P:K= 10:30:20, hasten blossom in this condition, honey sugar、milliongolds and paris Oncidium’s flower rate can achieve 70% above, langxi is 55% and redcat can achieve 66%.The buds’ differentiation of spider Oncidi-um must be treated by low temperature, after 60 days by using the treatment of 25～15℃(day night), flower buds rate can achieve 72.3%.In this paper, 6-BA has no obvious effect on the flower buds rate.更多还原
