摘　　要：度尾文旦柚裂果成为制约产业发展的关键因素,为探讨不同矿质元素对度尾文旦柚裂果的影响,开展糖醇钙镁硼锌等矿质元素肥料喷施对比试验。结果表明,经5个喷施处理的2个时期,度尾文旦柚的果实裂果率和大口径裂果比例均低于对照,其中糖醇钙镁硼锌处理的最低,裂果程度较轻。在度尾文旦柚生产上,建议在果实挂果期尤其是果实膨大期喷施钙镁硼以及高钾水溶性叶面肥,以减少裂果的发生。Fruit cracking of pomelo‘Duweiwendan’is one of the key factors restricting industrial development.In order to explore effects of different mineral elements on fruit cracking of pomelo‘Duweiwendan’,comparison test of spraying sugar alcohol calcium,magnesium,boron and zinc was conducted.The results showed that fruit cracking ratio and proportion of fruit with large-area cracking treated by five spraying treatment in two periods were lower than that of control.When spraying sugar alcohol calcium,magnesium,boron and zinc,fruit cracking ratio was the lowest and there was low level of fruit cracking.It is proposed that sugar alcohol calcium,magnesium,boron and zinc and f water-soluble foliar fertilizer containing high concentration of potassium should be sprayed in fruiting period,especially fruit expanding period for reducing fruit cracking.
