1、光照:紅掌是喜光照植物,光照時間越長,紅掌的顏色就更鮮艷,反之則會變得暗淡發綠,注意避免強光直射,會灼傷葉片。2、土壤:選擇疏松、透氣、營養豐富的微酸性土壤最佳。3、養分:紅掌在正常生長期間,要注意每隔半月施一次液肥,開花之前需每隔一周噴一次磷酸二氫鉀,促進開花,使其花色鮮紅。

  紅掌的介紹

  紅掌是天南星科多年生常綠草本植物,葉自基部生出,綠色,革質,全緣,長圓狀心形或卵心形,葉柄細長,佛焰苞平出,卵心形,革質并有蠟質光澤,橙紅色或猩紅色。

  紅掌在不同生長發育階段對水分要求不同,幼苗期由于植株根系弱小,在基質中分布較淺,不耐干旱,栽后應每天噴2-3次水,開花期應適當減少澆水,增施磷、鉀肥,以促開花。

  紅掌生長對溫度的要求主要取決于其它的氣候條件,陰天溫度需18~20℃,晴天,溫度需20~28℃,在寒冷的冬季,當室內晝夜氣溫低于15℃時,要進行加溫。
