中文摘要：
在山地条件下,研究了水肥一体化栽培对‘神湾’菠萝植株生长,果实大小及理化品质、香气物质组成等的影响。结果表明,水肥一体化栽培的‘神湾’菠萝自然抽蕾时的青叶数、叶长、叶宽以及株高明显高于对照。水肥一体化栽培后,‘神湾’菠萝果实的果长、果径、单果鲜质量、折算单产显著增加;果实的可溶性固形物、蔗糖、可滴定酸质量分数显著提高,全糖及VC质量分数变化不明显,还原糖质量分数降低;果实中酯类香气物质总质量分数略微提高,烯类香气物质组分数减少、总质量分数略微降低。
英文摘要：
The effects of fertigation on growth, fruit quality of pineapple cultivar ＇Shenwan＇ was investigated. The results suggested that the number of green leaves, length and width of leaf, as well as height of pineapple plant at the point of naturally flower budding were significantly increased by fertigation treatment. The length, circumference and individual weight of pineapple fruits, as well as the yield were notably enhanced by fertigation treatment. Fertigation treatment also significantly increased the mass fractions of TSS, sucrose and titratable acid. Fertigation slightly affected the mass fractions of total sugar and VC of pineapple fruits, as well as declined the mass fraction of reducing sugar. The total mass fraction of ester aroma components of pineapple fruits was slightly increased. While the total mass fraction and number of alkene aroma components were slightly reduced by fertigation.
