<P><B>牵牛花种植技术</B></P>
<DIV>
<P>◇播种时间:买回种子后,仔细观察一下,找出“胚”的部位,其大小约1mm左右,呈白色,这里是根萌生的部位,所以一定要看清楚。将种子放入盛水的杯子,再用筷子搅拌一下,如果有浮在上面的种子,用筷子碰触一下,使其下沉。如果始终浮在上面,即是不好的种子,就算播种下去也无法发芽,可将这些坏种子丢弃。牵牛花的种皮十分坚硬,如果直接播种的话,可能要长达10-30天才能发芽,因此为了提早发芽或发芽整齐,就得将种子浸于温水内,24小时后就可以看到种子都胀得鼓鼓的,此时即可开始播种。浸水后仍不膨胀的种子,可能是因为过于结实饱满,因此可将种皮轻轻划破,以利吸水发芽,不过值得注意的是,不要伤及胚的部位。
◇栽培场所:牵牛花是相当强健的植物,对环境的适应能力也很强,只要日照充足及通风良好的场所均能生长。栽培场所至少需要6-8小时的日光照射,才能开出美丽花朵,但仅有西晒日光的地方不适宜。
◇花期管理:开花期间最好仍然能够接受日照,并保持土壤湿度。开花后若不想留种,应及早将残花剪去。
◇浇水要点:最好避免直接浇冷水,因为冷水会使土壤温度下降,而影响根部发育,使生长变差。最好预先储存经阳光晒过的水。避免在晚间浇水,因为很容易造成花苗的徒长,而影响日后的开花。
◇施肥要点:牵牛花是好肥植物,虽然它耐贫瘠,但是充分的养料往往可以使牵牛花长的更好。定植后,每隔15天施一次。</P></DIV>
