双层降温催花技术对蝴蝶兰抽梗时期及双梗率的影响

Effect of Double-layer Cooling on the Time of Pedunculation and the Rate of Double Peduncles in Phalaenopsis

为改良蝴蝶兰生产模式,以3个品种分别为台湾阿妈、爱丽丝以及安娜的蝴蝶兰成熟植株为试验对象,以传统的单一风机湿帘降温模式为对照,研究了双层覆盖及双重降温模式对蝴蝶兰植株抽梗速度和双梗率的影响。结果表明:在双层覆盖及双重降温模式下,蝴蝶兰的抽梗速度显著加快,3个品种完成100%抽梗的时间分别为28、27和37d,分别比对照完成100%抽梗提前8、7和17d,提前抽梗对于蝴蝶兰的商业化生产具有非常重要的意义。除此之外,在试验模式下,参试植株的双梗率分别达到100%、100%、32.2%,分别比对照提高57.9%、45.1%和1 363.0%。

In order to improve the production mode of Phalaenopsis,taking three varieties of mature plants as experiment materials,which were Taiwanama,Alice and Anna,the control was the traditional mode,the effect of double-layer coverage and double-layer cooling mode on the time of pedunculation and the rate of double peduncles of Phalaenopsis were studied.The results showed that the speed of pedunculation of Phalaenopsis was accelerated significantly in the mode.The three varieties of Phalaenopsis were 100% pedunculated in 28,27 and 37 d,and were 8,7 and 17 dearlier compared with control.The earlier pedunculation is very important for the commercial production of Phalaenopsis.Besides,the rate of double peduncles of three varieties was up to 100%,100% and 32.2% under the mode,and the increased amplitude was 57.9%,45.1% and 1 363.0% than the control,respectively.
