采用大田试验方法，以中国菠萝主栽品种‘巴厘’为试材，研究了叶面喷施柠檬酸、硫酸亚铁、硫酸亚铁＋柠檬酸、柠檬酸铁、柠檬酸铁铵对菠萝叶片总铁、活性铁、叶绿素含量及菠萝生长和产量影响，为防治菠萝叶片黄化提供依据。试验结果表明，6.67%硫酸亚铁溶液、0.2%柠檬酸溶液pH值均在2.80以下，叶面喷施酸性溶液提高了菠萝叶片活性铁、叶绿素含量，能促进菠萝生长，提高菠萝产量；柠檬酸铁在常温下难溶于水，对提高菠萝叶片活性铁、叶绿素含量及促进菠萝生长和提高产量效果不显著；柠檬酸铁铵、柠檬酸＋硫酸亚铁都能显著提高菠萝叶片全铁、活性铁及叶绿素含量，增加菠萝叶片数、D叶长度、宽度及产量，能有效防治菠萝叶片黄化。

In this work, the effects of foliar spraying of citric acid, ferrous sulfate, iron (III) citrate, ammonium ferric citrate, and ferrous sulfate + citric acid on the contents of total Fe, active iron and chlorophyll, as well as the growth and yield of pineapple were investigated. The results showed that foliar spraying of 6.67% ferrous sulfate and 0.2% citric acid solution, with pH values at below 2.80, both significantly increased the content of active iron and chlorophyll, as well promoted the growth and yield of pineapple. Iron (III) citrate was poorly solution in water at room temperature, and foliar spraying Iron(III) citrate did not significantly increased the content of active iron and chlorophyll, as well promoted the growth and yield of pineapple. Foliar spraying of ammonium ferric citrate and ferrous sulfate+citric acid significantly improved the contents of the total iron, active iron and chlorophyll in pineapple leaves, as well increased the number of leaves, the length and breadth of D leaves and yields, which effectively prevented etiolation symptom of pineapple leaves.
