营养液组分对朵丽蝶兰生长开花的影响

Effects of different nutrient solution on the growth and flowering of Doritaenopsis ‘White Castle’

采用循环潮水式Ebb&Flow灌溉系统栽培朵丽蝶兰(Doritaenopsis),以A、B、C 3种组分的营养液为试验配方,研究它们对朵丽蝶兰生长开花的影响。结果表明:3种处理对朵丽蝶兰的生长与开花均有较大影响,而C营养液处理的植株在鲜重、干重、叶面积、花梗长度、开花数量等指标上均优于A、B处理组,表明C营养液的配方最适合朵丽蝶兰的生长发育,并能有效提高朵丽蝶兰的开花品质。

In this experiment, Doritaenopsis plants were cultivated by automatically recirculating Ebb ＆ Flow irrigation system. Three different nutrient solution formulations of A, B and C were used to study their effects on the growth and flowering of the flower. The results indicated that all the three treatments affected greatly the growth and flowering of Doritaenopsis. However, the plants treated with C nutrient solution performed better than A and B treatments, indicating that C nutrient solution was the most suitable for the growth of Doritaenopsis and can improve its flowering quality effectively.
