兰花的生长、开花、繁殖要靠多种营养来维持,这些元素缺一不可,人们把这些元素统称为肥料。养兰该用什么样的肥料,众说纷纭。有人喜欢用农家肥,有人喜爱用化肥。笔者认为,养兰还是用化肥好。在谈化肥之前,先说说农家肥。农家肥即常说的有机肥,如人粪尿、禽肥、畜肥、豆粕、花生粕、菜籽粕、棉籽粕及自己配制的烂鱼虾和绿肥等。这些肥料取材方便,价格便宜,举手即得,而且肥效很大。但农家肥有许多缺点:其一,使用前必须经过腐熟、沤制,一般腐熟2年以上才比较理想。其二,使用量不易掌握,量小不能满足花卉的生长需求,量大则容易产生肥害其三,臭味难除,污染空气。其四,农家肥所含元素不全或某些元素不足,长期使用,兰株会出现缺素症。其五,极易感染病 Orchid growth, flowering, reproduction depends on a variety of nutrients to maintain these elements are indispensable, people put these elements collectively referred to as fertilizer.
