一、人工授粉的必要鹤望兰的花构造较为特殊:在蓝色的花舌(侧生的2枚花瓣靠合而成)中,雄蕊被紧密地包裹在小船般的舌囊中,而雌蕊柱头却突出在花舌外。由于雄蕊被隔绝封闭,导致鹤望兰在自花或异花授粉上的困难。在其原产地(南非),鹤望兰靠一种特定的蜂鸟传粉,我国栽培的只能靠人工授粉。
First, the artificial pollination necessary Strelitzia flower structure is more special: in the blue flower tongue (side of the two petals together), the stamens are tightly wrapped in the boat-like capsule, while the pistil Stigma but prominent in the tongue. Because stamens are isolated and closed, it leads to the difficulty of the Strelitzia reginae on self-pollination or cross-pollination. In its country of origin (South Africa), Strelitzia reginae is pollinated by a particular hummingbird, which can only be cultivated by artificial pollination.
