| 摘 要： | 采用大田试验方法，研究了玄武岩发育而成酸性土壤上叶面喷施七水硫酸镁、一水硫酸亚铁、七水硫酸锌对菠萝生长和产量影响，为在此类土壤上种植的菠萝施用中微量元素提供依据。试验结果表明：与对照(喷清水)相比，喷施硫酸亚铁显著提高了菠萝叶片长度、宽度、叶片数及叶片中叶绿素含量，提高幅度分别为9.1%、14.9%、15.9%、62.6%，且显著提高菠萝产量、单果重和商品果率，提高幅度分别为11.8%、11.5%、7.7%；叶面喷施硫酸镁显著提高叶片叶绿素含量，但对菠萝叶片长度、宽度、叶片数和产量没有显著影响；叶面喷施硫酸锌对菠萝生长和产量都没有显著影响。

| Abstract: | Based on experiment of field-cultivating on basaltic acid soil the growth and yield of pineapple were tested by foliar spraying MgSO4·7H2O, FeSO4·H2O, ZnSO4·7H2O, respectively, so as to provide the basis for applying trace elements on the pineapple in basaltic acid soil. The results showed that compared with the control (foliar spraying water), foliar spraying FeSO4·H2O significantly increased length, breadth, numbers and chlorophyll content of pineapple leaves by 9.1%, 14.9%, 15.9%, 62.6%, respectively; and foliar spraying MgSO4·7H2O significantly increased chlorophyll content of pineapple leaves, but did not significantly increased length, breadth, numbers of those and pineapple yield, and foliar spraying ZnSO4·7H2O did not significantly increased the growth and yield of pineapple. |
