紅掌喜陰還是喜陽 紅掌是喜陰植物還是喜陽植物

紅掌是喜陰植物,但如果長期養(yǎng)護(hù)在陰暗處,會(huì)導(dǎo)致植株生長發(fā)育不良,因此平時(shí)應(yīng)將紅掌放置在散射光照處,但是要避免陽光直射,以免植株被曬傷。紅掌喜溫暖,最適宜的生長溫度為21~32℃,所能忍受的最高溫為35℃,可忍受的低溫為14℃,溫度過低或過高都會(huì)導(dǎo)致植株枯萎發(fā)黃。

  紅掌的生長習(xí)性

  光照:紅掌喜光,如果光照太少,在光合作用的影響下植株所產(chǎn)生的同化物也很少,當(dāng)光照過強(qiáng)時(shí),植株的部分葉片就會(huì)變暖,有可能造成葉片變色、灼傷或焦枯現(xiàn)象,夏季光照強(qiáng)烈時(shí),需采取適當(dāng)?shù)恼陉幋胧?/p>

  水分:紅掌在生長期間需要較多的水分,但在冬季即使溫室的氣溫較高也不宜過多降溫保濕,因?yàn)橐归g植株葉片過濕反而降低其御寒能力,使其容易凍傷,不利于安全越冬。

  肥料:紅掌根部施肥比葉面追肥效果要好得多,液肥施用要掌握定期定量的原則,秋季一般3~4天為一個(gè)周期,夏季可2天澆肥水一次,秋季一般5-7天澆肥水一次。
