摘　　要：对出现缺镁症的台湾青枣树进行镁肥试验,结果表明:土壤施肥和叶面喷施硫酸镁均能提高台湾青枣叶片光合色素含量和叶片氮、磷、钙养分含量。单株施镁量200～400g,叶片镁含量最高,株施400g时达到最大值,叶片中叶绿素a、叶绿素b、总叶绿素和类胡萝卜素含量分别比对照提高22.14%、34.38%、25.31%、17.86%,并能促进叶片中氮、磷、钙、镁含量的均衡提高。The trail has been conducted with the added Mg fertilizer in lacked Mg jujube orchard.The result shows that the Magnesium sulfate can rise the content of photosynthetic pigment, nitrogen, phosphorus and calcium of the leaf. The magnesium content ia higher at dosage of 200-400g/tree, the tiptop is at 400g/tree.The content of chlorophyll A, chlorophyll B, total chlorophyll and carotenoids are higher of 22,14%, 34.38%, 25.31% and 17.86% than the control tree, respectively.
