菠萝一般能在砂土、砂壤土、粘壤土、砖红壤和泥炭土上种值,但重粘土不大适宜。菠萝因特别怕积水因而必须排水良好,故无论如何土层应有适当的厚度。菠萝通常需酸性土壤。无刺卡因种菠萝喜 pH5.6—6的土壤,但只要定期叶面喷施硫酸亚铁来防治缺铁病,在pH 高达7.5的土壤也能种植。其他品种,例如红西班牙种菠萝,则不大适应偏中性的土壤条件,因而只在 pH4.5—5.5的土壤上才能良好生长。

Pineapple generally can sand, sandy loam, clay loam, brick red soil and peat soil species value, but the heavy clay is not suitable. Pineapple is particularly afraid of stagnant water and therefore must be well drained, so anyway, the soil should have an appropriate thickness. Pineapples usually need acidic soil. Pineapple is a non-card because of the soil pH5.6-6, but as long as the regular foliar application of ferrous sulfate to prevent iron deficiency disease, the soil up to pH 7.5 can also be planted. Other varieties, such as the red Spanish pineapple, are less well-suited for the more neutral soil conditions and therefore grow well on soils with pH 4.5-5.5.
