掌握好人工授粉技术,种南瓜大丰收不成问题

南瓜属于雌雄同株异花植物,南瓜自然授粉主要靠蜜蜂等昆虫帮助完成,现在很多花友是阳台种植昆虫活动少,就要人工授粉了。

南瓜人工授粉很简单,下面图解南瓜授粉步骤。南瓜的是雌雄同株,每株苗上有雌、雄花两种花,当然只有雌、雄花传粉受精后,雌花才能结果,先来认识一下南瓜的雌花和雄花,以免授粉的时候搞错了。

图解南瓜如何授粉

左上边是南瓜雄花下边是南瓜雌花。

剥去雄花的花瓣,将雄花的花蕊在雌花的蕊柱上轻轻涂抹,使花粉粒粘附在柱头上,就完成了授粉的过程。

注意:如果不是在开花当天授粉的话,雄花就会失去授粉的功能。如种植西瓜或蜜瓜,也可以采取以上授粉方法。

授粉成功雌花底部的瓜就会变得更绿,日渐长大。

若授粉失败,雌花底部的瓜就变黄,不久后就会自动掉落。

人工授粉最好选在上午,此时是雌、雄蕊生长最旺盛的时段,授精率高,生命力强。

在自然界中,雄花完成传粉受精作用就脱落了。雄花又俗称“谎花”,就是因为光开花不结果。
