兰花冬季养护的注意事项

柠檬加盐
2017-05-25
随着空气温度逐渐降低,对室内盆兰水分供应甚为重要,应酌量多浇水,但同时还要注意浇水保湿,如果湿度过低可喷雾,以保证兰花有足够的湿度,防止兰叶枯尖。兰株经过夏季生长后,盆内养分消耗殆尽,所以在入冬前要重视施肥。方法是根施有机肥,每10天1次;叶面喷施氮肥,也是10天1次;二者可交替进行。根施有机肥的同时,可适量掺拌磷钾肥,以利于促蕾。

现在仍是软腐病、茎腐病及其他病害的易发季节,可用农用链霉素、百菌清、甲基托布津等杀虫剂轮流喷雾。阳光可增强兰草抵抗病虫害、抗御严寒的能力,所以在现阶段让兰草应该多''晒''太阳。

对于夏秋季开花的剑兰等兰花品种,花后应及时剪去花枝并补充养分,以壮兰株,同时对兰叶进行整理,剪去病叶、枯叶。
